They can be found when black holes suck in other stars. They’re interesting, but of no practical value to me and, as he points out, science has progressed so much that no one can understand it all any more.

Stephen Hawking talks about how the Aristotle theory of absolute space came to an end by the Newton’s theory that ‘rest’ and ‘motion’ can be the tkme state if an observer sees the event at rest or if he moves with the same speed as that of the event. Apr 18, Cait Poytress rated it it was amazing Shelves: Hawking wrote the book for nonspecialist readers with no prior knowledge of scientific theories. o

They believed that if an event is measured using two different clocks at different state of motion, they’ll have to agree on the same time, if clocks used are synchronized, which by now we know it isn’t. However, most scientists today are working on the theories themselves rather than asking such philosophical questions. Weak nuclear forces are the forces that cause radioactivityor when matter histkry energy.

brirfer Later, many argued that light must travel through a hypothetical fluid called Etherwhich was disproved by Michelson—Morley experiment that there is nothing called Ether through which light travels. An error in the book, or did I misunderstand anything? The end of the book, hisstory Hawking discusses the theories that scientists are currently trying to prove, started getting to be a bit above my head – in my lay opinion, I think it was a combination of Hawking getting a bit more vague and having fewer concrete facts and observations to state.

A Brief History of Time: I began watching Neil Degrasse Tyson’s Cosmos last year and it rekindled my interest in learning about physics and astronomy. The Special Theory of Relativity fo based on this, that light travels with a finite speed no matter what the speed of the observer is.

This book has been in historu T. Very readable, and I was actually surprised to realize I’d learned most of this information in an astronomy class I took in college. But in astronomy and in some other situations, regularities were observed. Logic doesn’t appear to be Hawking’s forte when it comes to seeking existential self-justification.

I palazzi vicino ai binari che, mentre noi viaggiamo stepuen treno, sembrano muoversi rispetto al panorama che invece resta fermo. Three years ago, I attempted to simplify my ideas in The Universe in a Nutshell, but I now gather that no one understood that, either.

So let’s start with Newton, who gave us the three laws of motion, which describe how bodies react to forces, and the theory of gravity. Attempts to do that have led to the occurrence of absurd infinitely massed particles or an infinitely small universe. A particle of spin 1 looks different in every direction, unless the particle is spun completely around degrees. Finally, he talks about the hawkung for a unifying theory that describes everything in the universe in a coherent manner.

The ti,e bang implied by the general theory of relativity indicates that a creator of the universe or God has the freedom to choose the origin and the laws of the universe. The example given in the book is of a double-headed arrow. My Brief History However, according to string theories, instead of the usual four space-time dimensions, the universe could have dozens of them.


Hawking thus proposes three possibilities: Thanks to the Doppler effect, we know that the universe is expanding as the light-shifts of stars veer towards the red end of the spectrum. I wanted to yell “Preach it, Mr.

Got good deal of information and understanding of theories. Unless we are sharing a mass delusion straight out of Philip K. The area of the event horizon of a black hole gets bigger whenever something falls into the black hole. The book does employ a number of complex models, diagrams, and other illustrations to detail some of the concepts it explores.

But you praise their efforts in their quest to understand it all. Quarks are very small things that make up everything we see matter. His results showed that the Universe is non-static. It’s a tiny bit shorter, more condensed, with more accessible images than those diagrams in the earlier version.

Maybe uistory repeat his explanation. After a few initial hiccups the first chapter’s historical survey of the evolution of human understanding was a touch treacly and almost lost methe book completely and remarkably succeeds at this.
