A Briefer History of Time

Time joined space as the fourth dimension. The uncertainty principle disproved the idea of a theory that was deterministic, or something that would predict everything in the future.

This was found not to be true by Newton's laws of gravity. One prediction that Einstein's theory makes is that time will go by slower when something is near huge masses. Only very large stars, called super-giants, are big enough to become a black hole. By the twentieth century, Edwin Hubble discovered that galaxies are moving away from each other, meaning that at one time they were all in one place.

Weak nuclear forces are the forces that cause radioactivityor when matter emits energy. The temperature of the universe cooled and the things inside the universe began to clump together.

He also thought that the sun and stars went around the Earth. Black holes are the central focus of the next chapter. When the universe was first beginning, it was infinitely hot. For example, if the universe formed and then collapsed quickly, there would not be enough time for life to form.

A great discovery of the twentieth century is that all matter is made up of only a few microscopic constituents and that only four fundamental forces control everything. Hawking explains the theory of the Big Bang which proposes that all matter was once compacted into a small area.

To find where a particle is, scientists shine light at the particle. If a universe expanded too quickly, it would become almost empty. For example, a particle of spin 0 looks the same from every direction. The idea of many universes is called the many-worlds interpretation. As is often quoted in the religious books — Seek, and Ye shall find.

Hawking's gift to the reading world was to spell out the same big and hugely puzzling questions, in words that ended with a note of hope. Since black holes had, inonly a hypothetical existence, and since the making of the universe was, and still is, a subject of pure speculation, it was an extraordinary achievement.

Since there is no such thing as a limitless microscope, we go as far in as we can and then theorize on why things behave as they do. At some point it exploded and the universe as we know it was created and time was started. First, he starts to look out into space.

Hawking also talks about light. The basic building blocks are quarks and leptons.

A Brief History of Time

The area of the event horizon of a black hole gets bigger whenever something falls into the black hole. Hawking realized that the event horizon of a black hole could only get bigger, not smaller. If the mass of a star is less than the Chandrasekhar limit, it will not turn into a black hole; instead, it will turn into a different, smaller type of star.

A Brief History of Time: From the Big Bang to Black Holes is a popular-science book on cosmology (the study of the universe) by British physicist Stephen Hawking. It was first published in Hawking wrote the book for nonspecialist readers with no prior knowledge of scientific theories/5(K).

So the one thing I learned from A Brief History of Time: From the Big Bang to Black Holes is that in any event, depending on what perspective you take, one must understand that our perspective is just that: ours.

Dr. Hawking points out that there are many others. Stephen Hawking’s popularization of modern cosmology, A Brief History of Time: From the Big Bang to Black Holes, made publishing history (and the Guinness Book of Records) when it remained on.
