The title of this book differs by only two letters from A Brief History of Time that I wrote in Later, many argued that light must travel through a hypothetical fluid called Etherwhich was disproved by Michelson—Morley experiment that stepen is nothing called Ether through which light travels. At the very least, you will begin to grasp the concept of circular time.

Jan 13, Rusty rated it liked it Shelves: La prima parte era molto semplice, la seconda When I learned that tome was a Briefer 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 best part is that it’s not one of those over-complicated books you have to waddle through and put down every 30 minutes.

A Briefer History of Time

In his book on gravity, Principia MathematicaIsaac Newton used complex mathematics to further support Copernicus’s idea. Luckily, I don’t think he plans on crushing me. Some theories say that light acts like particles even though it really is made of waves; one theory that says this is Planck’s quantum hypothesis.

Reviews of this book “Recommended to those who are interested in physics, cosmology, natural philosophy or the history of science” Jupiter Scientific “It’s one of a very few books in this category that continues to fascinate despite the fact that much of its contents stretch the reader further than is usually expected in a book of this sort.


Inflationary models and the idea of a theory that unifies quantum mechanics and gravity also are discussed in this chapter. By using this site, you agree to the Terms of Use and Privacy Policy.

Nevertheless, Newton believed that the universe was made up of an infinite number of stars which were more or less static. This discovery brought the concept of the beginning of the universe within the province of science. This was a mistake, as everyone has their own four-dimensional spacetime. But inwhen scientists were examining spectra of different stars, they found that some of the characteristic lines of the star spectrum was shifted towards the red end of the spectrum.

One of the pair of particles would fall into the black hole, and the other would escape. Apr 24, Jenny Reading Envy rated it it was amazing Shelves: To find where a particle is, scientists shine light at the particle. Thirty-seven full-color illustrations enhance the text and make A Briefer History of Time an exhilarating and must-have addition in its own right to the great literature of science and ideas.

A Brief History of Time – Wikipedia

Even after having so many facts, the concept of static universe persisted till the 20th century. Light rays, too, must follow geodesics in spacetime, as relativity predicts light will be bent by gravitational fields.

The New York’s Metropolitan Opera had commissioned q opera to premiere in —16 based on Hawking’s book. So, it was assumed that since some stars are red shifted, some stars would tiem be blue shifted. Very readable, and I was actually surprised to realize I’d learned most of this information in an astronomy class I took in college.

We’re searching for a grand unified theory, but haven’t got one, because general relativity and quantum mechanics are inconsistent with one another. He discusses two major theories, general relativity and quantum mechanicsthat modern scientists use to brierer the universe. At least if you’re a total civilian, which I am.

A Briefer History of Time – Stephen Hawking

The model for this is called the “hot big bang model”. Should i read this before A Brief History of Time? First, the universe would expand for a given amount of time and if the expansion rate is leser than the density of the universe leads to gravitational attractionit would ultimately lead to the collapse of the universe at the later stage.


Secondly, the universe would expand and at sometime if the expansion rate and the density of the universe become equal, it would expand slowly and stop at infinite time and would lead to somewhat static universe. As Einstein points out, time may be steohen, but mine’s more valuable than yours. Virtual photons have a spin of 1 and represent electromagnetic forces or the force that holds atoms together. Disorder, also known as entropyis histort to black holes.

I dont care how short he makes the next one.

With the advancement of the human broefer in the modern age, more regularities and laws were discovered. Of course, I took the time to explain this stuff to my family because it’s really interesting and fun. Goodreads helps you keep track of books you want to read. So like I said, if this tiny take on life An fime shorter version of a History of time There are some tough concepts to understand.

The star must be one and a half times the mass of the sun or larger to turn into a black hole. Maybe even repeat his explanation. We never observe it working in the opposite direction. The luminositybrightness and distance are related by a simple mathematical formula. A Brief History of Time: The stars are very far away from us, so we only observe their one characteristic feature, their light.
