He also thought that the sun and stars went around the Earth. This theory tries to explain these forces in one big unified way or theory.

A Brief History of Time Summary

Light waves have crests and troughs. The beginning of the universe is thought to have happened through something called the Big Bang.

This problem was solved when the idea of pairs of "virtual particles" was thought of. The boundary of the black hole is called the event horizon.

Thirdly there is the cosmological arrow of time, the direction of time in which our universe is expanding and not contracting. Quarks also have three "colors": Hawking also talks about how the universe could have been. Share via Email Like spacetime itself, Stephen Hawking seemed to appear from nowhere and expand rapidly to fill the publishing universe.

This small point is called a singularity. 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.

This means that when gravity affects two things, gravitons move to and from the two things. Only very large stars, called super-giants, are big enough to become a black hole. There are many problems with more than three space dimensions. Besides the force of gravity and the electromagnetic forces, there are weak and strong nuclear forces.

This means that when gravity affects two things, gravitons move to and from the two things. These waves happen in imaginary time. This idea seemed strange at first, but many people accepted it after a while.

But in astronomy and in some other situations, regularities were observed. Chapter seven contains another discovery about the universe, that it is the same in every direction. The spin of a particle shows us what a particle looks like from different directions.

The star must be one and a half times the mass of the sun or larger to turn into a black hole. He also realized that when two black holes combine, the size of the new event horizon is greater than or equal to the sum of the event horizons of the two other black holes.

Strong nuclear forces are the forces that keep the quarks in a neutron and a proton together, and keeps the protons and neutrons together in an atom. After talking about light, Hawking talks about time in Einstein's theory of relativity. So is it the greatest science book ever?

He experimentally proves it by sliding objects of different weights, and even concludes that both these object would fall at same rate and would reach the bottom at the same time, unless external force acts on them. Black holes are talked about in this chapter.

This means that when gravity affects two things, gravitons move to and from the two things. Aristotle, unlike many other people of his time, thought that the Earth was round.

Aristotle also thought that the sun and stars went around the Earth in perfect circles, because of "mystical reasons". However, scientists found a problem when they tried to say that light always traveled at the same speed.

Black holes are difficult to find because they do not let out any light. As for why humans experience these three arrows of time going in the same direction, Hawking postulates that humans have been living in the expanding phase of the universe.

The Doppler shift happens when something moves toward or away from another object.

Black holes are difficult to find because they do not let out any light. Because of the phenomenal success of A Brief History of Time, Hawking published a series of corrected, updated, and expanded editions, including a tenth-anniversary edition and an illustrated edition with more than photographs, diagrams, and computer-generated images.

They are not even consistent with each other. These ideas are about the thought that events stay in place over a period of time. Two spots that were previously one centimeter apart will now e two centimeters apart as measured along the surface of the balloon.

This idea seemed strange at first, but many people accepted it after a while. Sometimes more than one of these waves can interfere with each other - the crests and the troughs line up.
