Dark Matter and Dark Energy featured heavily. This stuff makes up 27% and 68% of the universe respectively, leaving only 5% for the stuff we can see – like planets and stars. It’s this 95% of stuff we know hardly anything, or nothing about that make scientists incredibly excited. These were ‘discovered’ when Hubble showed the universe is expanding at an accelerating rate, not being retarded by the pull of gravity. Hence, some other form of energy is pushing the universe to expand it faster and faster. Maybe the next Newton or Einstein is in utero, right now, ready to unleash his or her intellect on solving the mysteries of Dark Matter and Dark Energy. Surely that’s not much of an ask – expecting answers to the misunderstood 95% of the universe. It’ll happen – to be sure.
People who believe they are ignorant of nothing have neither looked for, nor stumbled upon, the boundary between what is known and unknown in the universe.” Astronomical instruments such as telescopes have allowed us to view distant objects in space with greater clarity and detail than ever before.I used to think a lot about Dr. Tyson... but after the last chapter this book got old. He basically called anyone who hasn't dedicated their life to science "inconsiderate". That's my take. p. 157 onward, he talks about the Cosmic Perspective and various implications. It's just given as a series of facts/ideas. But I think it's pretty deep, esp since his audience is for young people. Things like, The cosmic perspective is spiritual but not religious. The Cosmic perspective requries you see the possibility of a multiverse and whatever that implies for your reality. I think if you're a fiction writer, this whole section is bawler for opening up the mind. Science is not just about seeing, it’s about measuring, preferably with something that’s not your own eyes, which are inextricably conjoined with the baggage of your brain. That baggage is more often than not a satchel of preconceived ideas, post-conceived notions, and outright bias.” The cosmic perspective shows Earth to be a mote. But it’s a precious mote and, for the moment, it’s the only home we have.”
Long before anyone knew that the universe had a beginning, before we knew that the nearest large galaxy lies two million light-years from Earth, before we knew how stars work or whether atoms exist, James Ferguson’s enthusiastic introduction to his favorite science rang true. Yet his words, apart from their eighteenth-century flourish, could have been written yesterday. this introductory guide to the mysteries of the cosmos is genuinely accessible." — Summer Reading 2017, The Sunday Times

Who can ask for better cosmic tour guides to the universe than Drs. Tyson and Goldsmith?”—Michio Kaku, author of Hyperspace and Parallel Worlds My Thoughts: I thought this was well put together, with interesting facts and visuals. My only complaints are that at times it felt a bit preachy and I wish he had gone a little more in depth/explained better on some topics. (But I suppose it is meant for “young people” so maybe I should read the adult version.) I remember reading other books written by astrophysicists, like Carl Sagan’s Cosmos, Stephen Hawking’s A Brief History of Time, Trinh Xuan Thuan’s The Secret Melody or Hubert Reeves’ Patience dans l'azur. Somehow, in each case, and probably unbeknownst to their authors, these books have a distinctive poetic flavour, a sort of lyrical flight somehow, which is best expressed in this sentence by the Scottish astronomer James Ferguson, quoted at the end of Tyson’s book: of 5 stars 2 of 5 stars 3 of 5 stars 4 of 5 stars 5 of 5 stars Astrophysics for People in a Hurry by Neil deGrasse Tyson The book offers interesting perspectives on scientific phenomena and how they relate to the broader universe, making it an invaluable resource for anyone looking to better understand the cosmos."

Meaning he was strutting his stuff in his theoretical physics world, with just his mind and something to write with – and really clever experimental physicists since have confirmed his theories such as The Theory of General Relativity and Quantum Theory. Einstein’s remarkable work has truly stood the test of time. We are stardust brought to life, then empowered by the universe to figure itself out - and we have only just begun.” The power and beauty of physical laws is that they apply everywhere, whether or not you choose to believe in them. In other words, after the laws of physics, everything else is opinion.” If you ask us, the most important chapter of this whole book – the culmination to which all other chapters build to – is the last one, “Reflections on the Cosmic Perspective.”Since as much as we know – or, as in this case, have probably predicted well enough about the universe – there’s much more that we don’t know. The style is vintage Tyson – engaging, chatty and littered with historical and linguistic anecdotes..." — Times Higher Education Aprendí que la exploración y el anhelo de saber más sobre nosotros es más importante que muchas otras cosas.
And all of it promises to be a magnificent adventure! Key Lessons from “Astrophysics for People in a Hurry” He observes, “This universality of physical laws tells us that if we land on another planet with a thriving alien civilization, they will be running on the same laws that we have discovered and tested here on Earth---even if the aliens harbor different social and political beliefs.” (Pg. 38) Later, he adds, “All measurements suggest that the known fundamental constants, and the physical laws that reference them, are neither time-dependent nor location-dependent. They’re truly constant and universal.” (Pg. 44) Sentence Summary: From the beginning of the universe to our own solar system to the possibility of alien life, Neil deGrasse Tyson explains some of the fundamentals of astrophysics in a simple way younger readers can understand. The author has a special talent for distilling complex concepts into understandable language, making the book attractive to casual readers as well as those already familiar with astrophysics." Everything you need to know about Neil deGrasse Tyson's Astrophysics for People in a Hurry, in 1 paragraph.In terms of how our planet came to life, we know that it happened through a small dot that expanded at a huge rate. Still, it took 380,000 years to have light separate from matter. 14 billion years have passed by, and stars emerged in the process, one of which is our precious Sun. Lesson 2: Helium was discovered before it was found on Earth. He admits, “we are hamstrung in this analysis by not knowing what the dark matter is in the first place. If all mass has gravity, does all gravity have mass? We don’t know. Maybe there’s nothing the matter with the matter, and it’s the gravity we don’t understand.” (Pg. 84) He continues, “We have no clue as to what [dark matter] if… But we desperately need it in our calculations to arrive at an accurate description of the universe.” (Pg. 87) He goes on, “The worst that can happen is we discover that dark matter does not consist of matter at all, but of something else. Could we be seeing the effects of forces from another dimension?... If so, this could be just one of an infinite assortment of universes that comprise the multiverse.” (Pg. 89) Astrophysics for People in a Hurry is a very readable account of the creation of the universe and how the universe works, as related by Neil deGrasse Tyson.
