Hi Pat, Gasp, wheeze, gulp. Here is the complete filtered collection of text changes from the Roadmap Team. They are ordered by page number (except for the collection of ornamental quotes at the end of this file), so you should be able just to plow through from start to finish. This incorporates filtered versions of all change suggestions sent by White (Oct 3,5,6,8,11) Lester (Oct 6) Cominsky (Oct 6) Kniffen (Oct 6) Flanagan (Oct 6) Hertz (Oct 6, 7, 10) Kahn (Oct 7) Dermer (Oct 7) plus myself. Sterl Note: page numbers refer to the BE-Roadmap-Rev01.pdf file (at http://www.its.caltech.edu/~esp/seus/BE-Roadmap-Rev01.pdf ) I've tried to give enough of the originals in "replace" instructions that a general search will find 'em, but don't guarantee uniqueness -please check page #'s against -Rev01 pdf file! p. 1 Fonts in white sidebar are not uniform (at least in pdf) " 's greatest" and "ments show that we" look funny. p. 3 In Preface, replace paragraphs 2 and 3 ("Many science objectives... hard choices") by three new paragraphs: " This roadmap is about the future of the SEU theme. Many science objectives encompassed by the SEU theme have been given high priority by the science community through working groups, roadmap teams, and strategic planning processes. This roadmap draws upon broad community input, including the specific recommendations of recent consensus reports of the National Academy of Sciences such as {\em Astronomy and Astrophysics in the New Millennium} (2001) and {\em Connecting Quarks with the Cosmos} (2002). Many of the communities' science priorities could be realized within the next 25 years. This roadmap recognizes that, within the resources available, not all of these science objectives can be undertaken immediately. Constructing a roadmap clearly entails making hard choices. In this roadmap, the science objectives for SEU are presented and prioritized. The research programs and space missions required to address the science objectives are identified. The roadmap lays out a path that begins at the completion of the present program and leads to the future. " In final paragraph of Preface DELETE final phrase "the Research and Analysis...critical factors." so Preface ends "...and develop future ones." p. 5 Question 2 "What happens to space, time..." seems to be in a smaller font than questions 1 and 3. They should all be same size. p. 6 Replace "... fascinate the news media, ... and the American public." by "... fascinate the American public and compel the attention of the news media and the entertainment industry." p. 7 Roman type for "Preface....3" and "From the Big Bang to Black Holes....5" entries. Replace "RFAs" in both Part I by (....10) and Part II (....58) by "Research Focus Areas", or if that doesn't fit, by "Focus Areas". delete self-evident "Contents......7" line delete "Beyond Einstein....11" line under Chapter 1. delete "Beyond Einstein....43" line under Chapter 3. Consider adding a bit of text color, and help separate parts, by putting "Part I. Beyond Einstein...9" in the color of its sidebar, "Part II. Cycles of Matter and Energy...57" in the (now different I hope) color of its sidebar, and on p. 8, "Part III. Supporting the Roadmap...79" in the color of its sidebar. p. 8 Rename Chapter 10 "External Factors" (also in the actual chapter on p. 87!). Delete "Appendix A.....91" Replace "A.1" by "Appendix A" Split/Replace: "A.2" by "Appendix B Acronyms" and by "Appendix C Glossary of Terms" Replace "A.3" by "Appendix D" Replace "A.4" by "Appendix E" p. 10 Replace "Objectives and RFAs" by "Objectives and Research Focus Areas" - put labels in front of the numbers, i.e. Objective 1. Find out ... Research Focus Area 1. Search for ... Research Focus Area 2. Determine the ... Objective 2. Observe how ... etc The box starting "Beyond Einstein is a bold attack..." should be elegantly and prominently laid out. It is supposed to be a sort of frontispiece. p. 11 Remove the section title "Beyond Einstein". In "What powered the Big Bang?" section: in first paragraph Replace "NASA's MAP spacecraft" by "NASA's Microwave Anisotropy Probe (MAP)" Append "in the first place" to end of "all-important wrinkles", to read "...all-important wrinkles in the first place?" in second paragraph replace "as well as the simple," by "as well as the simplest:" in third paragraph replace "Measurements by a mission of the" by "Measurements by missions of the" Caption on the figure "Boomerang CMB Map" should be "BOOMERanG and its map of the cosmic microwave background." p. 12 In box replace caption "The COBE four-year sky map. Wrinkles in the radiation relic of the Big Bang discovered by NASA s COBE satellite in 1992." by "The map of the sky's cosmic microwave background (CMB) resulting from a four-year observation by NASA's Cosmic Background Explorer (COBE) satellite. In 1992 COBE first discovered these wrinkles in the relic radiation from the Big Bang." In "What happens to space..." section: in first paragraph Replace "ripples they make in spacetime." by "waves of distortion they make in spacetime." in second paragraph p. 12 (last line) -13 replace "...throughout the Universe, detailing the conversion..." by "....throughout the Universe. These sounds will detail the conversion..." p. 13 In Feynman quote box, citation replace "From NAS CPU Report" by "{\em From Quarks to Cosmos}, report of the Committee on the Physics of the Universe" Sidebar text "When we talk about...our ears hear" should end with a period "." Replace "The detection of gravitational waves will..." by "The measurements of gravitational waves will..." p. 14 Delete first paragraph under "The Beyond Einstein Program" ("Two facility-class missions, Constellation... edge of a black hole"). Replace by "The program has three major elements that work together towards the visions of directly observing the birth of the Universe and directly imaging matter near the edge of a black hole. The cornerstones of the program are two Einstein Great Observatories, Constellation-X and LISA. These will provide dramatic new ways to answer questions about Black Holes, the Big Bang and Dark Energy. The second element is a focused line of moderate-sized Einstein probes, each dedicated to the study of a specific deep question. The third element is a supporting program of forward-looking technology development, theoretical studies and education and public outreach. Alone, no single mission can solve the profound questions that confront us. Together, the three elements will enable us to grasp these questions, prove the technology to enable the vision missions, and inspire the next generation of scientists and engineers." After "Einstein Great Observatories" section heading, add new paragraph: "While these two missions are focused on specific observational goals, the capabilities they provide are so dramatically new that they will also provide a broad science return that will impact all areas of astrophysics, as have Hubble Space Telescope and the Chandra X-ray Observatory before them." In paragraph starting "The Laser Intererometer Space Antenna (LISA)..." put those words in bold face to create a pseudo-subsection header. In paragraph beginning "LISA will probe space and time", replace "around black holes, the ripping noise..." by "around black holes, and the ripping noise..." and replace "singularities, and possibly even whispers..." by "singularities. It may even hear whispers..." After paragraph ending "LISA will plot...under extrememe conditions." add a new paragraph: "LISA measurements of merging black holes will provide a new yardstick with which to measure the Universe and constrain the nature of Dark Energy. LISA will also measure waves from black holes in the first structures of the Universe to collapse. It will measure thousands of binary stars in our Galaxy, yielding new insights into the formation and evolution of stars." In paragraph starting "The Constellation-X mission will consist...", put the words "The Constellation-X mission" in bold face, and replace "collecting area" by "sensitivity", and replace "other planned missions." by "other planned missions for X-ray spectroscopy." replace "instrumented with detectors covering" by "instrumented to cover" After paragraph ending "Current instruments...to freeze the motion." add a new paragraph: "Constellation-X will dramatically increase our ability to obtain high resolution X-ray spectroscopy of faint X-ray sources. This will enable us to constrain the nature of Dark Matter and Dark Energy by observing their effects on the formation of clusters of galaxies. These measurements, and those by the Dark Energy Probe, LISA and the Inflation Probe, will each constrain different possible properties of Dark Energy, and together lead to its understanding. Constellation-X's high resolution spectra will provide fresh diagnostics of the speed, density, temperature and composition of gas in galaxies and exotic stars throughout the Universe, allowing new studies of their nature and evolution." Replace "Together, LISA and Constellation-X...centers of galaxies." by "To understand the origin and nature of the giant black holes in the centers of galaxies requires both LISA and Constellation-X, working together to cover all four of these processes." p. 14 bottom - p. 15 top replace "missions will allow NASA to address those" by "missions will address those" p. 15 Figure should be larger -either run across full page (covering sidebar) (or, less desirably) consider using full page and running it landscape. In sidebar starting "Gravitational waves are vibrations...." replace "have been dancing" by "have been hurtling" Move this sidebar to p. 16 (more precisely: it should be on page section titled "The Ultimate Vision") [the sidebar on p. 16 should swap with it to p. 15 -see p. 16 entry below] Move the "How did black hole form and grow?... reveal how giant black holes formed" (ends on p. 16) paragraph up just before the section beginning "What is the mysterious energy pulling the Universe apart?" [i.e. so that black holes come before dark energy as everywhere else in text] Merge into one the two paragraphs beginning "What is the mysterious energy.." and "To understand this energy, we must..." after ..."wide-field space telescope, add a new paragraph: "Independent diagnostics of the dark energy will be crucial to verify the validity of results and to increase the precision of the measurements. The Inflation Probe and LISA will provide completely independent cosmic yardsticks with which to measure the effects of dark energy, and Constellation-X will observe the first clusters of galaxies, whose evolution depends critically on dark matter and dark energy." The italicised questions that open the paragraphs of the "Einstein Probes" section, "How did the Universe begin?" "What is the mysterious energy pulling the Universe apart?" "How did black holes form and grow?" are not well separated from text. Could they be in bold italics or some other more distinctive and readable font? p. 16 add onto "perform a census of hidden black holes." to read "perform a census of hidden black holes, providing targets for Constellation-X." Truncate the sidebar text "The dark energy filling..." at "...all the billions of galaxies." Delete the rest (which is repeated word for word, easier to read, in the box on p. 25). MOVE THIS sidebar text "The dark energy filling...billions of galaxies." to the sidebar on p. 15 (more precisely, it should be on the same page with the paragraph starting "What is the mysterious energy pulling the Universe apart? is a question..." ) In "The Ultimate Vision" replace "This observatory would give us" by "The Big Bang Observer would give us..." Replace "Constellation-X will detect the spectral..." by "To explore the end of time and the edges of space, Constellation-X will measure the spectral..." and combine this paragraph with the next one starting "But there is no substitute.." Replace period at the end of that paragraph by comma, and add "revealing directly the fate of matter near a black hole." so it reads "...could take this epochal picture, revealing directly the fate of matter near a black hole." In "Technology" "The vision missions' Black Hole Image and Big Bang Observer need..." needs two commas: "The vision missions, Black Hole Image and Big Bang Observer, need..." ^ ^ Replace "extensive refinements" by "many refinements" Replace "extraordinarily stable" by "very stable" DELETE the sentence "With appropriate investment, these can be developed within a few years." This page needs a picture -e.g. of, and next to, "Technology" or "Research and Analysis" sections. p. 17 Replace second to last sentence "We will follow matter...left over from the beginning." by "We will follow matter to the very brink of black holes and detect 'particles of time' left over from the beginning of the physical Universe." p. 18 This looks like a good place for a legislated NEW BOX: Image for the box: http://www.its.caltech.edu/~esp/seus/egret_allsky.gif Text for the box: ----------------------------------------------------------------- The Gamma-Ray Large Area Space Telescope (GLAST) is the highest priority mission already under development in the Structure and Evolution of the Universe theme. This roadmap assumes its completion and scheduled launch in 2006. GLAST is an international and multi-agency (NASA and DOE) project. GLAST builds upon the success of the EGRET high-energy telescope on the Compton Gamma Ray Observatory. The Large Area Telescope on GLAST will map the sky in one day at the same flux level that EGRET could achieve in one year. With 100 times the sensitivity of EGRET and broader energy coverage, GLAST will study the processes that expel relativistic plasma and accelerate particles near the black holes believed to lurk in Active Galactic Nuclei and Gamma-Ray Bursts. It will elucidate the origin of energetic gamma-radiation from pulsars, and the accleration of cosmic rays in supernova remnants. It will help identify the many EGRET sources whose nature remains a mystery, and search the universe for gamma-ray signatures of hypothesised decaying particles of Dark Matter. ------------------------------------------------------------------ p. 19 [Sorry about rearrangements in this chapter -test market feedback has made them important; if they are confusing, please call or send drafts!] Replace "A mysterious new field generated" by "A still-mysterious form of energy generated" Move the entire section titled "The Beginning of Time" (i.e. the title and all the text from "The Universe is expanding, and abundant evidence... ...inflation field that powered the Big Bang." including the box about Penzias and Wilson on p. 20) to p. 26, and insert it after the end of the gravitational wave section (i.e. after "...quantum noise from the inflationary Universe.", just before the "Dark Energy and the Accelerating Universe" section.) -i.e. the new order of sections in chapter 2 will now be *Edges of Spacetime and Black Hole Horizons *Cosmic Cacophony: Gravitational Waves *The Beginning of Time *Dark Energy and the Accelerating Universe p. 20 In box, delete "(R.K. Sachs...Zel'dovich)" Also in box, replace "In 2001, a NASA balloon flight, BOOMERanG..." by "In 2000, an NSF/NASA balloon flight, BOOMERanG..." ^ ^^^^ Also in box, Replace text at end "and dark energy density." by "and dark energy density, all indicators of the contents of the Universe." p. 21 replace "these alien regimes" by "these so-far invisible regimes" Move the sidebar quote "The most incomprehensible...Einstein" so it is next to the previous section ("The Beginning of Time") -e.g. p. 20 or 19. p. 21 In box, replace "that at its edge time stops, and nothing can escape..." by "that time stops at its horizon's edge, and nothing can avoid..." p. 22 In box, "Because E=mc^2", the E, m and c of the equation should be in italic type. Also in box, after ": its mass and spin." add new sentence "Electric charge is shorted out." Also in box, put quotation marks around "bald" in "as bald as Einstein's theory..." in text Add "The" before "Black Hole Finder Probe" to read "The Black Hole Finder Probe will survey..." and add "The" before "Black Hole Imager" to read "The Black Hole Imager will create..." In "Cosmic Cacophony:" section: replace "a new form of energy called" by "a novel form of energy called" replace "to the point that we are sure..." by "to the point that we are confident..." ^^^^^^^^^ Capitalise Watts in "watts is radiated". p. 23 in box, In last bullet, delete "where time comes to a halt" Delete the top pair of images. Move the (Chandra deep field) image out of the box to compress the text. Give this image a caption (preferably along its side, in the blue bar, or in some other way that doesn't create so much white space): "Ground-based observations of the field of X-ray sources in this 12-day exposure by the Chandra X-ray Observatory show that many of them are shrouded by dust; many others remain unidentified." In white letters in the sidebar next to this box on Chandra X-ray Observatory, insert (as much of as fits...) "Public interest in the Chandra X-ray Observatory has led to more than 850 newspaper articles and wire stories ---including 27 in the NY Times, Washington Post, and USA Today ---and more than 10 newscasts, including CNN, ABC, CBS, and NPR." HOWEVER: This (Chandra X-ray Observatory) box and its images are out of place in this section on gravitational waves. The box on p. 24 should be here instead. The Chandra X-ray Observatory box (and its new Public interest sidebar) now on p. 23 should be moved up to p. 21 (or at least somewhere next to the text of "Edges of Spacetime and Black Hole Horizons" section instead of next to the gravitational wave section). [Note: Nick White constructed a long box on GPS. If it was inserted, I think it should be deleted -the text already on GPS on p. 23 "airplanes using GPS navigation would miss their runways by miles" will suffice.] p. 24 In the box whose text starts "In 1967, the first radio pulsar" Try to make it occupy less space -e.g. widen to move into the blue bar, and run text below the (replaced by new, improved by Pat!) graph along the side. Replace the box text "prize for the discovery" by "prize for showing" At end of that box text "...rate Einstein's theory predicts." replace period by comma and add text: "...rate Einstein's theory predicts, due to gravitational waves. The gravitational waves from binary stars like this await direct detection by LISA and the Big Bang Observatory." Then move this box to p. 23 (see entry for p. 23). ADD A NEW BOX about the 2002 Nobel Prizes: possibly on this page (p. 28 next to section titled "The Einstein Great Observatories" would be another suitable location too), NEW BOX text: "The 2002 Nobel prize in physics was shared by scientists who opened two new windows on the Universe. In 1962 {\textbold Riccardo Giacconi} detected for the first time a source of X-rays outside our solar system, using a detector in the nosecone of an Aerobee rocket. He also detected the sources of X-rays that most astronomers now believe contain black holes. Giacconi constructed the first X-ray telescopes, which have provided us with completely new images of the universe. His contributions laid the foundations of X-ray astronomy. The company (AS\&E) that built these early astronomical X-ray detectors also developed high resolution Computed Tomography (CT) scanning of the human body, and is now a world leader in the X-ray inspection systems used to detect illegal substances and weapons in packages, trucks and cargo containers. Neutrinos are particles which interact only weakly with ordinary matter, so neutrino detectors must be enormous and precise. The gigantic instruments constructed by {\textbold Raymond Davis Jr.} and {\textbold Masatoshi Koshiba} detected neutrinos from the sun, and confirmed the prediction that the sun is powered by nuclear fusion. Koshiba's instrument also detected the neutrinos from Supernova 1987A, proving that supernovae create hot neutron stars which cool by radiating neutrinos. Davis and Koshiba created the field of neutrino astronomy. Their experiments also made the unexpected discovery that neutrinos have mass ---the neutrinos in the Universe have as much mass as all the stars! Constellation-X is the next great step in the development of X-ray astronomy blazed by Giacconi. And like the instruments of Davis and Koshiba, LISA will open for mankind a completely new window on the Universe and create the field of gravitational wave astronomy." Suitable images are at (winners faces) http://www.nobel.se/physics/laureates/2002/ Better Giacconi photo at: http://www.phys-astro.sonoma.edu/BruceMedalists/Giacconi/giacconi.jpg [Nick White can probably have someone find a more interesting picture of Giacconi with a rocket launching or a nosecone.] (Kamiokande detector -note small rubber boat with 3 people:) http://www-sk.icrr.u-tokyo.ac.jp/sk/photo/high.html Best to impress with scale is sk_01.jpg, but sk_04.jpg is also ok. (Ray Davis detector:) http://www.sns.ias.edu/~jnb/Gif/37cldetector.jpg (caption for Davis detector photo can be found beneath the image at:) http://www.sns.ias.edu/~jnb/Papers/Popular/JohnRaypictures/johnraypictures.html Swap the box on dark energy ("It was Edwin Hubble's...") with the box on p. 26 ("Many NASA missions have laid..."), or otherwise make sure the dark energy box is on a page of the "Dark Energy and the Accelerating Universe" section, which begins on p. 26) p. 25 Replace "the LIGO observatories" by "the Laser Interferometer Gravity-wave Observatory (LIGO)" after this Replace "waves from the loudest sources. The {em Beyond Einstein} flagship mission LISA will be far... wide variety of sources." by "waves from some sources of high-frequency waves. The {\em Beyond Einstein} Great Observatory LISA will operate in a broad band at much lower frequency. It will detect entirely different sources in great numbers, and with exquisite precision." Replace "LISA's strongest signals will probably be tones from very loud binary massive black holes." by "LISA's strongest signals will probably be tones from black holes spiraling into other supermassive black holes." In box starting "It was Edwin Hubble's": Replace "which confirmed that the expansion of the Universe is actually accelerating due to" by "which found the farthest supernova. This supernova gave us confidence in the measurements implying that the expansion of the Universe is accelerating due to ..." In the graphic in the box: black out the words "Supernovas dimmed by dust". The box (with "Farthest Supernova figure") should be next to the "Dark Energy and the Accelerating Universe" section on p. 26, not in the gravitational wave section. p. 26 In the box, add "The" before Hubble Space Telescope In the box, split the paragraph starting "Hubble Space Telescope" in two, and modify to read: "{\em Hubble Space Telescope} has helped to find and measure the distant super-novae that have forced us to accept the reality of dark energy. ^^^^^^^^^^^^^^ X-ray missions, including NASA's {\em Chandra} X-ray Observatory and {\em RXTE}, ESA's {\em XMM-Newton} and Japan's {\em ASCA} ^^^^^^^^^^^^^^^^^^^^^^ have discovered X-rays from matter spiraling into black holes, illustrating the potential of Constellation-X." ^^^^^^^^^^^^^ Also in the box, change "has led to the discovery of the interaction" to "has supported the discovery of the interaction" Also in the box, Delete the sentence "GLAST will study...spinning black holes." Replace it by a separate paragraph (between Swift and Astro-E2 paragraphs): "GLAST will provide more sensitivity and energy coverage than ever before for the study of high-energy emissions from particles accelerated in gamma-ray bursts and in the jets from spinning black holes in galactic nuclei." Also in the box, modify the last paragraph starting "Astro-E2 will.." to "{\em Astro-E2} will be the first to use (for bright sources) the micro-calorimeter detectors also to be used for Constellation-X. {\em ST-7} and {\em ESA's SMART-2} will provide a flight comparison of two disturbance reduction technologies competing for use on LISA." This "Many NASA missions" box on would make much better sense at the end of Chapter 1, say on page 18. Replace top line of text "studied by optical telescopes." by "studied by optical and X-ray telescopes." In the first paragraph of the section "Dark Energy and the Accelerating Universe" Replace "Is empty space really empty?" by "Is empty space really empty? Inflation models predict that it was not so in the past, and it may not be so today either." Delete "---a symbol, Lambda, with an unknown value---" Replace "The value of Lambda is set"... by "The unknown magnitude of the cosmological constant is set"... In bottom paragraph, replace "But we have no theory of dark energy; anything we learn..." by "Since we have no theory of dark energy, anything we learn..." ^^^^^ ^^ p. 27 Replace "When we understand the physics of the dark... another profound question: will the Universe last forever?" by "Because dark energy seems to control the expansion of the Universe, we cannot predict the fate of the Universe without understanding the physical nature of dark energy. As we develop this understanding, we will be poised to answer the profound question: will the Universe last forever?" After "technology to study this effect." add a sentence: "Constellation-X, LISA and the Inflation Probe will provide independent constraints to verify and increase the measurement precision." p. 27 In the equation "E=mc^2", the E, m and c should be italic. last line. Replace "to resolve the event horizon of" by "to image the event horizon of" p. 28 Replace continue paragraph at top "The first element is ... development, and scientific research." by "The central element is a pair of Einstein Great Observatories, Constellation-X and LISA. These powerful facilities will blaze new paths to the questions about Black Holes, the Big Bang and Dark Energy. They will also address other central goals of contemporary astrophysics (discussed in Part II of this roadmap). The second element is a series of competitively selected Einstein probes, each focused on one of the science questions. The third element is a program of technology development, theoretical studies and education, to support the Probes and the vision missons: the Big Bang Observer and the Black Hole Imager. The program offers competitive opportunities for mission leadership, technology development, and groundbreaking scientific research, with goals that excite the public." In "The Einstein Great Observatories" section Replace "The National Academy of Sciences has recommended both missions as high priorities for this decade in its decadal survey {\em Astronomy and Astrophysics in the New Millennium.}" by "The National Academy of Sciences' decadal survey {\em Astronomy and Astrophysics in the New Millennium} developed community consensus on the most important science questions and funding priorities. It recommended both LISA and Constellation-X as high priorities for this decade." At the end of the paragraph "Constellation-X will extend... unprecedented sensitivity" add "Constellation-X will also observe the first clusters of galaxies, and be able to search for spectral features from the surfaces of neutron stars, which could finally determine the properties of matter at nuclear density." Replace "LISA will open a new window on the Universe, tuning to gravitational wave. Through this window we will observe..." by "LISA's gravitational waves offer an entirely new way to sense action in the Universe. Through them we will hear..." at bottom, replace "starting in 2010" by "starting around 2010" p. 29 In "National Priorities" box, replace "program complies" by "science program complies" In "Interagency Connections" box, at end replace period in "many of the Einstein Probes." by comma, and add "as they have in the GLAST mission." to read "many of the Einstein Probes, as they have in the GLAST mission." In "International Connections" box, at end replace "the instruments are competed" by "the instruments are competitively selected." Can the 3 boxes be spread around in a more artistic way so they aren't all in a row on one page? (e.g. put "National Priorities" box on p. 28 near the text of the "Beyond Einstein: The Program" section that starts on p. 27, put the "International Connectons" box next to the "The Einstein Great Observatories" section on p. 28, and the "Interagency Connections" box next to the "The Einstein Probes" section on pp. 28-29 in text at bottom of p. 29 Delete entire sentence: "Dark energy was discovered too...Committee (AASC)." also replace "much more expensive" by "much more ambitious" p. 30 BE Timeline figure should be larger: run it across the full page (covering the sidebar). In "Competition Strategy" box, After "President's Management Agenda." add sentence: "The scientific goals and mission metrics are clearly defined." replace "Maximal competition" by "Maximal citizen-centered competition" Delete "competed" in "This competed approach will ensure" to read "This approach will ensure" replace period at end "...approach to the missions." by comma, and append to read "...approach to the missions, promoting innovation through competition." p. 31 in "An Integrated Program" section, replace second paragraph "The measurements of speeds...parameters for the Black Hole Imager mission." by "Constellation-X will constrain the distribution of X-ray emitting matter near black holes. This an essential step, both to prove the feasibility of imaging X-ray emission close to the event horizon, and to optimize the design of the Black Hole Imager vision mission." p. 32 At end of paragraph ending "imaging capabilities have far outrun spectroscopy." add sentence: "One third of the sources in {\em Chandra} X-ray Observatory deep fields are too faint for optical or X-ray spectroscopy and their nature remains a mystery." Change bullet "Observe broadened iron emission lines in" to "Observe relativistically broadened emission lines from" p. 33 In box on Constellation-X, "cyrogenic" should be "cryogenic" Also in that box, replace "CZT detectors" by "Cadmium-Zinc-Telluride detectors" p. 34 In box, the multiplication symbol X is too tall (on pdf anyway) (should be approximately "m-height" sans serif square X -see original pdflatex document) It appears 3 times. Also there is a funny box around the "1" after the second X. There should be a figure next to LISA section here (or p. 35) Save space for one to arrive any day now from Don Davis... p. 35 DELETE the sentence "These strategies all require... large-scale detector arrays." p. 36 In box starting "One implementation", a space is missing before the 10 in "about 10 sq. degrees" which should also be spelled out: "about 10 square degrees." In the L2 figure, how about making the figure more informative, by adding a LISA triangle along the yellow earth orbit half way along the arc between earth and L5, and adding to the box text: at the beginning add "Many of the {\em Beyond Einstein} missions require thermal control, so they must be located far from earth." then continue with existing text "The L2 point...of the Earth-Moon system." and add after this "Constellation-X and the Inflation Probe will fly near L2, like the current MAP mission. LISA's stable 5 million kilometer baselines require that its spacecraft orbit the sun in orbits trailing the Earth's." p. 37 In top paragraph replace "density component, which will be"... by "density component, first detected in 2002, and to be"... p. 38 In box, replace "(CdZnTe; CZT)" by "(Cadmium-Zinc-Telluride)". p. 39 The figure should be larger (across the full page, covering sidebar) in chart of the gravitational wave spectrum, replace the leftmost mission "PLANCK (ESA/NASA 2007)" by "INFLATION PROBE (NASA)" (keep the italic explanation "Polarization map ..." as is). Move the "quantum fluctuations in the very early Universe" up and stretch it to cover the whole width of the figure (or continue it with "..........................." all the way to the right). Shorten the LISA blue bar slightly (just a bit right of -2 on log f scale) and squeeze in a new red bar (same color as Planck and the "quantum fluctuations"), with the following underneath: "BIG BANG OBS (NASA)" and somehow indicate by spreading the "Laser tracking of drag-free proof mass in spacecraft orbiting sun" that this applies to both LISA and BIG BANG OBS. Hyphenate "interferometers" under GEO so that that bar of text can be squeezed farther right to fit under its the bar. At right of the frequency bar, after "log f" add "[Hz]" in roman type. This chart should perhaps be jazzed up by a graphic artist better than the hack who made it (me), e.g. by using better fonts and adding to the frequency/period bar a wave whose wavelength decreases to the right like the one in http://www.its.caltech.edu/~esp/seus/emspec.jpg p. 40 replace "This gas as it nears the event horizon. This will" by "This will require spectroscopically resolved imaging at the wavelengths of X-ray lines." There should be a figure next to the "Vision: A Black Hole Imager" section, for example the one on page 24 of http://www-conf.slac.stanford.edu/labastro/pdfs/D3_Begelman.pdf (just the figure, not the words) "Simulated Black Hole Imager view of an accretion disk around a black hole. Bending of light rays by the black hole makes the back side of the disk appear raised." p. 43 In sidebar, replace "African Saying" by "African Proverb" under "Lightweight, grazing..." section, replace last sentence "Several more years...design phase" by "Engineering test units of both SXT and HXT mirrors are under development: glass substrates with surfaces replicated from precision mandrels for SXT and HXT, and an alternative replicated nickel shell design for HXT." under "X-ray calorimeter" section, replace last sentence "Both have...a challenge" by "Both have made substantial progress toward the required energy resolution of 2 eV. Multiple approaches to fabrication of high-quality arrays and multiplexed readout amplifiers are under development." p. 44 The multiplication symbol after "Changes in the 5" is too big.

Several types have been demonstrated which meet the noise requirements, and lifetime and space testing are planned. Correction signals are sent to the thrusters by gravitational reference units (GRUs), which also serve as the reference mirrors for the laser measurement system. Improvements in existing GRUs (such as those flying on NASA's GRACE mission) that will extend LISA's sensitivity below 10^{-3}Hz are under development."

This was a key event. The dust absorbed light, and protected subsequent stellar nurseries from the damaging effects of ultraviolet light. The dust hides these nurseries from optical and ultraviolet instruments, but is transparent to the infrared light that the dust emits. For the farthest sources, most of this emission is shifted to wavelengths that are inaccessible from the ground. For this reason, far infrared and submillimeter telescopes in space should find these distant sources to be almost as bright as more nearby sources, making such telescopes powerful cosmological tools." p. 65 Move the last sentence of paragraph 2: "Submillimeter interferometers ... will provide." to the end of the next paragraph.

Most of the line radiation that cools collapsing gas clouds is not accessible to ground-based investments such as the Atacama Large Millimeter Array (ALMA). Crygenic single-dish space telescopes will provide direct measurements of these lines, and with new large format arrays, be vastly more effective for deep surveys. Submillimeter interferometers in space will eventually offer detailed images, complementing the huge increases in sensitivity that single-dish instruments will provide."

It would also be helpful to replace the blue-grey background of the "Visible" box with a rainbow. p. 81 In second sentence of Explorer Program section Replace "can be completed" by "can be developed" Section ends prematurely. Should continue "mandate. But we are sure they will continue to be astonishingly influential."

After "in the 1980s and 1990s." add new sentence: "Today's theoretical ideas are bolder still." This section also is truncated (at least in the pdf version) at "Ground-based observations will support gamma-ray" It should continue, and have an additional subsubsection on Archival Research: "burst studies by SWIFT, AGN observations by GLAST, black hole studies by LISA and the Black Hole Finder Probe, and LISA's white dwarf studies. The Dark Energy Probe will make use of spectroscopy by larger telescopes on the ground. \subsubsection{Archival Research} As data from previous and ongoing NASA missions mounts, so too does the value of archival research. Data mined from NASA's archives have led to a better understanding of important and interesting astrophysical phenomena. These archives are growing rapidly in both content and diversity. More sophisticated software tools would support searches spanning multiple archives, facilitating valuable scientific investigations long after an observatory has ceased operation. The proposed National Virtual Observatory would provide this capability. " p. 87 Rename chapter "Chapter 10.

Einstein's Cosmological Constant was a special form of dark energy. "Event Horizon" definition should be "The boundary of the region around a black hole from which nothing can escape." "Graviton" definition should be "The quantum particle associated with gravitational waves, which carries the gravitational force." Add to glossary before "Interferometry": "{\textbold Inflation.} Name for models of the very early Universe involving a short period of extremely rapid expansion, blowing what is now the observable Universe up from a tiny region that light could cross in that period to one that light could not cross. This process makes the Universe very smooth and flat." In "Neutron Star" definition "car" should be "core" and to avoid semantic confusion split into two sentences: "...massive star. Produced by..." "Singularity" definition should be "A place where spacetime becomes so strongly curved that the laws of Einstein's general relativity break down and quantum gravity must take over. Found inside black holes, and perhaps at the beginning of the big bang." Definition of "Z." should be "The symbol for the amount of Redshift. The ratio of ... emitted light. The most distant known galaxies and quasars have values of z=6 or greater." Paul Hertz requests the following additional Glossary entries: Dark Energy. A possible residual energy in space from which all light and matter have been removed ("vaccuum energy"). Generally predicted by Feynman's theory of virtual particles, but with undetermined strength and properties. Believed to be responsible for the accelerating expansion of the Universe. Doppler Effect. An observer receives sound and light from bodies moving away from her with lower frequency and longer wavelength (see Redshift), and from bodies moving toward her with higher frequency and shorter wavelength. The shift in frequency increases as the speed of the body increases. Quantum Mechanics. The well-tested theory of the behavior of matter on the microscopic scales of atoms and computer chips, where light waves and particles share common properties. String Theory. A theory that what we perceive as particles are actually vibrations on strings or membranes in respetively a 10 or 11-dimensional space. These theories resolve the incompatibility between general relativity and quantum mechanics, and unify them. Cosmological Constant. A term Einstein added to his equations of the general theory of relativity, but later rejected when Hubble's observations seemed to indicate it was not needed. Can be interpreted as a special form of Dark Energy. p. 97 Replace "A.3" by "Appendix D (same font as Appendix A on p. 91) Delete the "index.html" from the end of "http://chandra.harvard.edu/" Delete the "index.cfm" from the end of "http://sci.esa.int/home/planck/" p. 99 Replace "A.4" by "Appendix E" (same fonts as Appendix A on p. 99) p. 100 Add "Lynn R.
