    I only read a few pages because the author despite being a professor of astrophysics doesn't sound very scientific at all I abandoned the book on page 7 when he says The burden of proof now falls on the pessimists meaning those who don't believe there are advanced civilizations out there are the ones who have to prove they don't exist Uh hello? Any neurons firing up there? The burden of proof always lies with those making an assertion that something exists not on those who don't believe it without proofHe also says that our history of life on Earth shows that we are not the first Um OK where exactly is that shown? With what scientific method? And two paragraphs later he admits that science has proven no such thing and yet he makes these grandiose claims and expects us to just swallow them? What are we in church? I am of the mind that there is probably life out there intelligent life too but untilunless we have proof we cannot say that there is or accept someone's assertion that there is scientist or not Until there is proof it's mostly just wishful thinking I find it hard to believe that we're the only life when there are billions of galaxies teaming with stars and planets but that is not proof that there are advanced alien civilizations If the rest of this book is like the first few pages then I think Adam Frank probably needs to revisit Science 101 Perhaps if I continued reading I would find that it gets better but I have absolutely no reason to think Adam Frank will be different in the rest of the book when he's anti scientific in the beginning I would have a very hard time putting any credence in his words

    Adam Frank assumes the mantle of famous Astrobiologists and exoplanet thinkers like Carl Sagan and Frank Drake in considering where the human project fits in the greater cosmos covering the history of Astrobiology which really came into its own in the age of nuclear winters and moon shots and growing environmental awareness Frank covers where studies of Venus and Mars by probes elucidated issues we face on Earth and how the Exoplanet discoveries of the 1990s put some numbers to the Drake euation with the discovery of so many exoplanets and many that seem to be rocky worlds in their star's habitable zone The author shares how our understanding of Martian dust storms gave us insights to nuclear winter and changed the game in regards to cold war policy with nuclear weapons How Venus's runaway greenhouse effect added to our own climate change theories How the exoplanet revolution made us think our civilization's prospects as we become a major player on our planet's systems The message is that as we grow powerful like the magician's apprentice we have to figure a way forward in our civilizations climate crisis bottleneck and figure a way forward for ourselves It is not to save the planet the planet will hardly notice if we leave the stage but to save ourselves and guarantee our future Definitely a book for big thinkers

    Take everything you think you know about aliens and throw it out Light of the Stars is a brilliant and fascinating look into the world of astrobiology and its implications for Earth’s future Using a combination of science history and narrative Frank illuminates how humans as an intelligent civilization are driving the course of Earth’s evolutionary fate He asserts that we are most likely not the only intelligent civilization to have existed in the cosmos and by taking this concept seriously we can begin to understand our full impact on our planet He illustrates how we can learn from other planets and other universes throughout time and literally space to broaden our understanding of what it is like to be an intelligent civilization in the driver’s seat Frank’s ability to take complex scientific theory and break it down into palatable portions is a gift Light of the Stars is indeed brilliant both in substance and execution


  4. Lauren Lauren says:

    In Light of the Stars Frank surveys the last decades' leap into space and exo planet discovery as well as the burgeoning field of astrobiology It is a fascinating read both for its history and its futurism This book would also be a great textbook for an astrophysics class accessible and comprehensive in scopeI recently read The Sixth Extinction An Unnatural History and that served as a great companion piece to this looking at earth's changes shifts over the millenia and then this book putting Earth into context amongst all the other systems and galaxies

    98th book for 2018I can't work out why this got so many five star reviews You'd think from the title and description it would be interesting take on the latest findings on exoplanetary research and it's application to the environmental management of the Earth However it's nothing of the kind It's mostly a very padded rehash of old stuff Fermi's Paradox; the Drake Euation; the Venus and Mars landers Whole chapters are devoted to what could have been summarized in a matter of sentences The final part of the book talks about exoplanets and their implications to earth sciences but is very superficial This would have made a nice article somewhere but never deserved to be bloated into a book 2 stars

    It's all about the experiment that the universe is conducting on the planet Earth this civilization project We've made it this far It's a uestion of how long will humanity surviveThe book basically starts out with the creation of the planets in our solar system specifically Earth and goes through the harsh eons as it cools develops water develops continents life oxygen and variations that we see outside our windows in a zoo or a museum The writer then goes into how we began investigating our closest neighbors Venus and Mars and the investigations of various climatic models Eventually the uestion of other worlds and alien civilizations received focus Which in turn lead to the Drake Euation and Fermi Paradox Parts of the euation have slowly been answered over the decades We now have an idea of how many stars are in the galaxy as well as how common exo planets arePreviously it was thought that nuclear war was the last part of the Drake Euation But what if it is actually climate change and the impact humanity has on the planet? Millions of years ago the first microbes produced oxygen as a waste product Produced so much that it led to a massive extinction event which has forced what few anoxygenic phototropes to survive into the dark depths of the ocean near geothermal vents which are close to the Earth's surface at the time of their dominanceWhat if the human impact on Earth did the same? Drove the climate into conditions which made human life unsustainable? We as a civilization would become extinct the Earth would simply create another new major species and continue spinning merrily on it's wayAnd that is a major point that Frank I believe is trying to make The impact that the major species has on the planet and in order to achieve technological advances must continue to make that impact when using energy Thousands of computer models have been run with variations of population growth changes in energy sources high impact to low impact and whether the civilization develops sustainability or drives itself into extinctionAnd that part of the Drake euation is still unknown Frank can call it bio technical probability or pessimism lines on how long an exo civilization can survive but it basically comes down to whether or not our civilization experiment will survive And no one knows that answerIn the end it was not what I expected but I am glad that I got the chance to read it

    Wherever there's a book or lecture or podcast about the size of the universe count me in I'm fascinated by the subject and Light of the Stars is an excellent addition to the genre Frank writes clearly about the possibilities of technologically advanced civilizations throughout the universe how many there might be and how long they might last He writes persuasively because he includes a range of scientific inputs astrophysics astrobiology sociology evolutionary science to develop his analysis and because he's willing to distinguish scientific endeavors from speculation I can't say I'm convinced by his ideas; however I am persuaded to consider them seriously Additionally this book is about a whole lot Frank uses thinking about alien worlds ie he uses the light of the stars to give fresh insights into the evolution of the earth the evolution of civilization here and the interdependence of those evolutions He then proceeds to look at the possibilities for the future of the earth and human life His tone seems just right neither scolding about our doomed fate nor denying there's a problem He has a point of view an argument but he's not argumentative I won't replay Frank's thinking here but I will say Light of the Stars is mind bending and paradigm shifting Frank provides new ways to think about climate change and the interplay between mankind and the earth as well as what we can learn from possible alien worlds I'm no scientist so I can't confirm or rebut his thinking I can say I'm a bit wiser having read Light of the Stars and I enjoyed the journey along the way

    To date there are 528 reviews of this book and its average is only 386 stars This seems vexing considering the fact that it is probably one of the most important books to come out in 2018 My only guess is that his inclusion of his skepticism line might have muddied that waters I feel unualified to know whether the skepticism line is something I should accept As of now I am not sold However the rest of the book was top notch In fact this book is exceptional not simply for its subject matter keeping the planet habitable for humans and other oxygen greedy species but even so for the vast ground it covered when recounting the history of climate research If you don't know who Vladimir Vernadsky is that is because until now he has not really gotten his due Adam Frank brought his research front and center and showed how from the time of Vladimir Vernadsky onward  climate research earth's systems science flourished If we do not understand the history of climate research and indeed the history of our planet  a history that created the very atmosphere we depend upon for our lives than we cannot make informed decisions In fact even if we take into account everything we know which is a lot it is still difficult to know what changes we need to make and actions we need to take in order to save our planet We do not even know if it can be saved In an effort to help save it Frank and others are running computer simulations that will hopefully play a role in informing policy The programs are far from giving optimal answers There are just so many possible scenarios of how this can all play out Even if we get fairly solid answers from his latest work which is extremely important work will the politicians take it into account? Will it filter down to voters in society enough for them to take action? Who knows but these are extremely meaningful things to think about I read this book twice because it was clear that once I finished I needed to go back and take notes In Light of the Stars Adam Frank not only detailed how Earth's climate changed over time and why it matters but also provided an extradorinaiy history of climate change Frank's history reached all the way back to Carl Sagan's research on Venus if you are unfamiliar with this research this will be a real treat as well as investigation into the climate on Mars and then Frank took the reader all the way through present day and into the future of exoplanet research which will inform society even about how and why climates change Frank wrote about the ways in which we probed our in order to unlock the record or its changing climate over the past 45 billion years The incredibly detailed manner in which the history was told ensured that the average reader can answer What do we know about climate change on Earth and other planets and how do we know it? Most importantly Frank's focus is ultimately on the thermodynamic process that creates and changes climate For example is life itself something a planet uses to do work? The great biosphere scientist Vladimir Vernadsky asked this uestion The public freaked out at the mere mention from any scientist that Earth might be a living system Yet all work from later scientists working on the biosphere demonstrated that Earth does indeed regulate itself like a body does breathes like a body does and uses life the biosphere to remain active and alive In my estimation looking at the planet from this perspective that of thermodynamics is the only meaningful way to do soOne important thing this book does is give credit to the work of Lynn Margulis Just like many other scientists Margulis didn't get it all right but she was a revolutionary in what she got right Way ahead of her time strong in the face of criticism and the politics of science and because of all of that she was able to change the way we thought about evolution I was extremely happy to see that Frank didn't jump on the band wagon of scientist who have of late been trying to destroy her well earned reputation for her work on the theory of endosymbiosis At the same time Frank skillfully created an exceptional history of others who contributed to our knowledge especially Vernadsky as well as clear up some misconceptions left by pasts scientists such as Vernadsky Lovelock and Margulis He also made it clear why the naming of the Gaia hypothesis was so unfortunate Lovelock and Margulis would have received a lot credibility if the crystal loving hippies hadn't latched onto their Mother Gaia notions and misunderstood them so But that is what you get when you go to your neighbor William Golding who wrote Lord of the Flies for advice when naming your hypothesis  A name really can make or break an idea Renaming Gaia Earth Systems Science was surely a help Early on in the book Frank discussed the chemical composition of the atmosphere and how the climate will change if the chemical composition changes We have a wonderful blanket of greenhouse gasses to which we owe our very existence Without greenhouse gasses the planet would not have been habitable for humans at all So it's not that green house gasses are bad It's just that they have to be at just the right concentration to support fragile human life Consider oxygen Current levels of oxygen hold steady at about 21% of Earth's atmospheric composition What would happen if those gasses rose a bit higher to about 30%? The atmosphere could not support life because any old lightning bolt could set the atmosphere on fire Luckily for us life itself regulates the percent of oxygen in the atmosphere As long as we don't mess with the living things too much we can keep that percentage pretty steady The same complex regulation is present with other greenhouse gasses such as carbon or methane They need to be at trace amounts to optimally support life on the planet If too much CO is sent into the atmosphere but volcanoes or by human made factories and other human made contributions then it changes the atmospheric composition and if it changes too much it can become what is called a runaway greenhouse effect in which it is too late to bring levels back to where they need to be for life to be sustainable Calculating the euilibrium temperature of Earth is very simple math that can be done by first year undergraduate astronomy students I hope politicians read this book and learn just how simple it is to understand about how energy flows and cycles through and out of Earth If you do not understand this simple formula you should not be allowed to join in any discussion of climate change policy Of course there are many complex aspects of climate change that still need to be worked out For example other books examine the net effects of the 22 year sunspot cycle on Earth's climate These are difficult to determine But the least someone should know is how to calculate the euilibrium temperature of Earth A simple version goes sort of like this  Earth without an atmosphere would have an euilibrium temperature of zero  degrees Fahrenheit  But with an atmosphere the euilibrium temp is the climate  we experience now Change that atmosphere and the climate will change too much In order for the earths climate to remain fairly stable over time and not be in long periods of a boiling cauldron or a frozen snow mall the amount of energy that comes in from the sun needs to eual the amount of energy that is radiate it out at the right rate If too much energy is trapped inside the atmosphere by the greenhouse gases a planet will become too hot Trapping energy makes things hot Consider Venus' atmosphere which is all CO2 The COS trapped greenhouse gasses in the atmosphere creating a runaway greenhouse gas effect that resulted in an absolutely sweltering planet that cannot support life If too much energy is allowed to evaporate out and not get trapped it will make a planet too coldThis is what happened with snowball Earth The greenhouse gasses of Earth have only a spattering of CO2 If CO2 levels rise then of course too much energy gets trapped Our place in the solar system is called the Goldilocks Zone for a reason We are at just the right distance from the sun to have an atmosphere that can support earth IF we do not mess with the composition of the atmosphere too much When too much CO2 is present such as on Venus hydrogen gas is allowed to float away Volcanoes already produce a lot of CO2 There is no uestion that humans should be very careful about adding if they plan to continue depending on Earth as a home planet One good thing about the aftermath of volcanic eruptions is that water can bring much of the CO2 back underground But if humans spew CO2 into the atmosphere the hydrogen that floats away can no longer participate in making the water that sucks the CO2 underground So many climate change deniers like to pretend the science just isn't settled Most of the science is settled Basic chemistry has been settled for a very long time We know what happens when you add or subtract chemicals from a medium Different reactions happen We know that when you add CO2 to the other greenhouse gasses found in the atmosphere it helps to dissociate hydrogen from the oxygen that makes the water we need to keep us from experiencing a runaway greenhouse effect Similarly we know from studying Mars that if CO2 levels are high but there is no atmosphere the CO2 cannot be trapped It radiates out too uickly No trapped energy means cooler temps It's very basic science backed up by very basic math energy in v energy out It's not unsettledAdam Frank asked his readers to think about that for a second and reminded the reader that all of these people denying climate change seem to understand nothing about basic physics Where a rock is formed on the earth determines its shape color density  Being closer to a heat source makes up the salt further from that heat source makes it granite and even further makes it less dense rock  How hot or cold and entire planet is is merely an extension of this simple physics Depending on what you have in the atmosphere and what you have coming out of the earth it’s going to change not just rock but temperature on that rock it’s not rocket science  it’s just rock science  The best thing about Adam Frank's discussion in this book is that it follows the slogan Follow the money When you want to understand corruption of course you follow the money In Frank's case the slogan would be Follow the energy Once you do that things become very clear Frank also included a really nice section about Trade winds and Hadley Cells Our planet spins which makes wind patterns much interesting and complex Every rotating planet with an atmosphere has trade winds Warping winds can bring things like the polar vortex of 2014 His inclusion of trade winds was to show that Earth is not a special case The principles of physics laid out in this book apply to all planets If scientists know if a planet has or does not have an atmosphere spins or does not spin is close to or far from a star and so on they can make predictions The we know about other planets in the universe the we will continue to inform our knowledge of how planets work in general  In addition to including what we know about other planets Frank of course included what we know about our own He looked at how the Earth developed from a young planet to now and how organisms developed upon its surface He went through all the extinctions well covered in many books but beautifully covered in this one Most notably it is essential for humans to understand the history of cyanobacteria my very very favorite bacteria When cyanobacteria came on the scene it like all species ingested energy and created a waste product That waste was oxygen Oxygen was poisonous to everything living on Earth at that time including cyanobacteria We love their waste We take nice deep breaths of that waste In fact if we are having trouble breathing we humans often go to the hospital and breathe in the purest form of that waste Yum But make no mistake oxygen killed the vast majority of species alive at the time Those who survived did so only if they were able to find new niches like an animal gut or the hot springs of Yellowstone We humans create a lot of waste Our waste from factories farming and just about every aspect of daily living is CO2 It's poisonous to us Maybe not to whatever AI will come later Who knows But there is no uestion that the living green stuff on Earth and the vast majority of species that eat all that green stuff are poisoned by high levels of CO2 Basically we are changing the atmosphere just as cyanobacteria did We are in danger of killing most of what is currently living on our planet We can keep choosing to do that or we can make ourselves even slightly scientifically literate and make informed choices that give our species a better chance at survival

    What practical use is research into possible extraterrestrial live and civilizations?We need a new frame to think about our own planet and our relationship It's just false to all the evidence that we don't affect the habitability of Earth It's unhelpful providing no useful path forward to think of ourselves as a completely malign destructive forceWe need a new story to tell ourselves that correctly places us as an active force on Earth currently doing a lot of damage out of our ignorance until now but able to change direction and through use of our growing knowledge able to make different useful decisionsAdam Frank looks at both the history of our thinking and investigation of the idea of alien life up to and including the recent explosion of discovery of extrasolar planets and what that means for the likelihood that other technologically advanced civilizations at least have existed and the history of our growing understanding of our real impact on the habitability of Earth for us and our technologically advanced civilization It turns out that that history of growing understanding of the crucial factor of our contribution to global warming goes back not to the 1970s but to the latter part of the 19th centuryHe looks at how early life changed our planet to make in habitable for life like us the crucial fact that it's not Earth we need to worry about protecting but ourselves Earth and life will go one almost regardless of what we do but we might not and how even the study of certainly lifeless Venus and so far not proven to harbor life Mars have enhanced our understanding of Earth and our relationship to it Even understanding that planets at all sizes and types are fairly common in the universe and that therefore it's wildly unlikely that we're the first technological civilization to exist expands our understanding We further need to understand whether it's common possible or wildly unlikely for civilizations to survive the technological and environmental bottleneck we are currently struggling throughWe want to be a civilization that survivesIt's a fascinating book and well worth reading RecommendedI initially borrowed this book from my local library and then bought it

    Light of the Stars wasn't uite what I expected I don't remember what I did expect but I'm so glad I read it because I loved itOne element that I totally didn't expect was the discussion of climate change Specifically how a lot of our understanding of climate change has come from studying other planets as well as looking deep into our own planet's history It was unexpected but so interesting The book also largely focuses on the idea of an euation that could provide a very concrete idea about the possibility of life on other planets Normally the idea of following the creation of an euation would not interest me at all but this one is a really interesting euation Moreover Frank is a really good writer which only improves what is already an interesting topicI've seen reviews from other readers who didn't love this book because it covered a lot of information they already knew Certainly this is a book for the everyday person interested in space and aliens and it doesn't expect much background knowledge of the reader So it probably wouldn't be all that entertaining to those who already know a lot about astrophysics and the like However for me someone still testing these waters and very much a humanities student it was a very interesting book And I'll emphasise again because it's not always the case it's very well written tooSo if Light of the Stars sounds interesting to you I absolutely recommend it It's fun and interesting and informative I was engaged from start to end which is rarely the case for me with non fiction even if the topic is interesting
