I liked how they took you through the discovery of the cosmos and how we got to the point where discovering dark matter and dark energy was possible.
Que livro gostoso de ler. Panek explica da concepção da ideia de Big Bang à descoberta recente de matéria escura e energia escura. O livro é bem compreensivo e bem explicado, daqueles que expõe as perguntas e ideias que levam à formulação de uma nova teoria, além dos testes feitos depois que corroboram ela. Com uma explicação bem detalhada das descobertas de constantes.
Explicações como "segundo esta hipótese do Big Bang, o Universo ainda estaria a 1-4K de temperatura [...] confirmaram a temperatura" e outras do tipo deixam muito claro o valor das ideias cientificas, como foram formuladas e porque foram consideradas válidas. Ele deixa muito claro o processo todo de como mudamos radicalmente nosso entendimento do Universo ao longo do Século XX e porque estamos mais perdidos do que nunca – o que é muito legal. :)
Saiu em português como [b:De que é feito o Universo?|22022003|De que é feito o Universo?|Richard Panek|https://images.gr-assets.com/books/1398757622s/22022003.jpg|13076317] e recomendo demais. Ele só perdeu o Nobel de Física de 2011 para os propositores da expansão com energia escura, mas não está muito desatualizado. Li um trecho para o episódio de Fim do Universo e a melhor coisa que fiz foi resolver ouvir todo.

This is now the third or fourth book I've read on the modern history of cosmology, particle physics, etc. I keep hoping that if I read enough of them, I'll eventually catch on. Some I learned in the book (which I dearly hope are reasonably accurate, even if garbled in writing):
* Only 4% of the universe is actually observable. The rest is dark matter and dark energy.
* I had heard before that there wasn't enough observed matter in the universe to keep it from imploding (exploding?), but I hadn't realized that the reason the universe doesn't actually crash down on us is because of dark energy as well as dark matter.
* This is connected to Einstein's E=mc squared. Matter and energy are the same thing, so it's ok not to be able to observe sufficient matter (or even dark matter) so long as there's enough energy to make up the difference.
* Physicists and astronomers are extremely clever at devising experiments and observations to test theories. (Well, I guess I knew that one before, but I was reminded of it.)
* Their research conferences are apparently way more lively than the economics and policy research ones I go to.

This book reads like a detective story, and shows the race that existed to find and discover the nature of dark matter, and the phenomenon that we call dark energy. If you ever wondered about the make up of our universe, check out this book.
The Masonic fraternity recognizes there is a Grand Architect of the Universe and this work documents humanity attempts to understand what we experience and propose a multitude of theories but it seems we are only aware of about 4% of it as baryons and can only speculate about any meaning! There seems to be evidence of an unimaginable big bang beginning with astonishing heat that now has deminished to an expected about 3
degrees Kelvin temperature. Even though there may have been that singularity there is no evidence of an origin point and all locations are identical to all others! The universe appears to be expanding more rapidly with no bounds. We have no awareness of the substantial major components of this universe and likely no one will confirm it and can only speculate the architecture!

I found it rather boring, actually, and not *that* well organized. I feel like he should have focused either more on the people or more on the science or more on the competition and less on just random facts or all three of them combined. He spent a whole lot of time talking about the biography of Vera Rubin, who didn’t figure much in the actual events except for a few small times. And he randomly gave little one line descriptions of many scientists who he actually talked about more. Then little anecdotes in weird places about random people and events. It felt to me a bit like a list of names doing random stuff.
As always, though, I’m concerned that my lack of interest may actually just be due to my lack of ability to concentrate with audio books. Or maybe the narrator’s style or something, as opposed to the actual quality of the book.
The afterword was kind of cool and interesting, though. So...... there’s that.
