Und the center of our galaxy; black holes performing gravitational waltzes with visible stars; the cymbal clash of two black holes colliding releasing ripples in space timeClear compelling and profound Einstein’s Monsters reveals how our comprehension of black holes is intrinsically linked to how we make sense of the universe and our place within it From the small uestions to the big ones from the tiniest particles to the nature of space time itself black holes might be the key to a deeper understanding of the cosmo. I feel somewhat bad rating this 4 stars because to be honest I m not well versed in astronomy I never took a class Physics euations have been known to kick my ass and I m not sure that my issues with understanding the material were Impey s delivery or my own lack of familiarity with the material I like to flatter myself in saying I have a less terrible time with conceptual elements here but in truth you do need a certain amount of math to make sense of why things are one way and not the other For instance the Heisenberg uncertainty principleHe has some anecdotes scattered throughout particularly in the notes which you should read and I enjoyed the delivery of those So he s than capable of telling a good storyAs a history of science anything which gives credit to graduate students anyone beyond the PI okay maaaybe that s a low bar and acknowledges barriers faced by repressed minorities in whatever setting is a win If you re going to tell a story about scientists don t try to pretend they aren t people Impey manages to work this into the overall narrative which IMO is the right way to do it It s as much part of the story of discovery as hunching over a computer tapping out numbersNot that it isn t outside the scope of this book but I do want to highlight that there are concerns around how telescope hosting countries end up exploited or at least the locals do not benefit as much as they contribute I recall a vague mention of protests against the TMT here although not so much some of the controversies in Chile

Einsteins Monsters

Black holes are the most extreme objects in the universe and yet they are ubiuitous Every massive star leaves behind a black hole when it dies and every galaxy harbors a supermassive black hole at its center Frighteningly enigmatic these dark giants continue to astound even the scientists who spend their careers studying them Which came first the galaxy or its central black hole What happens if you travel into one instant death or something weirder And perhaps most important how can we ever know anything for sure abou. This is Black Hole 101 Most books about astronomy are very difficult to understand because they expect you to have a degree in physics Not this one I understand almost everything Impey is trying to say So Einstein s general relativity predicts black holes We now have proof that they exist everywhere Stars are constantly balancing 2 forces gravity and energy release The former pulls it in and the latter expands it When fuels are finished gravity becomes stronger and the star collapses Small ones collapse to white dwarves medium ones collapse to neutron stars Big ones collapse to become black holes where density is gasp infinite at the centre called the singularity There is also the event horizon where nothing even light can escape where escape velocity is also infinite Black holes have different masses exactly how each can have the same infinite density at the centre but different mass is mind boggling I just cannot compare 2 infinites but that is general relativity Black holes have been proven through binaries where 2 solar entities circle each other They sent out different waves that can be detected and they obey the laws of general relativity Active black holes are uasars or blazers which have bright accretion discs a la the show Interstellar Those were formed when stars were gobbled up by the black holes half joining them and the other half expelled and end up circling the black hole Active uasars are rare and happened mostly in the early age of the universe Eventually all the stars are gobbled up and black holes become uiet and unseeable only to decay slowly according to Stephen Hawking Each galaxy has a gigantic black hole at the centre whose mass is eual to the total mass of stars in the galaxy They hold the core stars and allow them to rotate around the centre Black Holes allow us to test general relativity in the space time distortion caused by mass and gravitational waves which were released when black holes collided Our GPS technology must take into account gravity s distortion of time space or else positions will be off by 10kmno Google Map A solid 5 star book for the layman

Chris Impey î 1 CHARACTERS

T black holes when they destroy information by their very natureIn Einstein’s Monsters distinguished astronomer Chris Impey takes readers on an exploration of these and other uestions at the cutting edge of astrophysics as well as the history of black holes’ role in theoretical physics from confirming Einstein’s euations for general relativity to testing string theory He blends this history with a poignant account of the phenomena scientists have witnessed while observing black holes stars swarming like bees aro. This is a phenomenal book by a master scientific writer Black holes are perhaps the most facinating piece of our universe Science philosophy and reality itself boils at a blackhole I couldn t possibly recommend this book any brilliant

    This book was wonderful It's always great to read something where you can tell the author truly enjoys what they do I have a very basic physics background and knew pretty much nothing about cosmology astronomical physics or black holes for that matter going into this I was worried that I wouldn't be able to follow any of the concepts or I would get lost easily but Impey did a great job making the subject matter digestibl

    This isn’t a book for sciencespace beginners like me It will help if you have a general understanding of physics and science before you read this The author does use good analogies references poetry and includes recaps that increase understanding That said a lot of this went over my head I gave up reading the footnotes about halfway through which I do think helped with the flow of information But I liked t

    Its rare to find a died in the wool science practicioner who can talk about their field in such an accessible and informative way but that's Imprey for you Fortunately his field is the most interesting in all of physics t

    Phew To get a baseline of my ignorance when news last month of the first images of a black hole my first thought was “huh? haven’t there been pictures of black holes for decades?” Fortunately I was drawn to Chris Impey’s book on my local library’s new book shelves and got a bit of a schooling Impey provides a thorough historical survey of Einstein’s “monsters” and removes all that is monstrous replacing it with
