Quotes About Cosmos

Most stars just fuse hydrogen into helium, but larger stars can fuse helium into other elements. Still larger stars, in turn, fuse those elements into slightly bigger ones, and so on.

Probably the simplest hypothesis... is that there may be a slow process of annihilation of matter.

it tells me that consciousness is primary to the physical universe.

What opened up before me was, for lack of a better word, a space, but not our ordinary concept of space, just the pure awareness of a realm without form and void of content. And into that realm came a celestial entity, which was the emergence of the physical world. It was like the big bang, but without the boom or the blinding light. It was the birth of the physical universe. In

People and their dwellings were such a thin dust on the surface of the globe, like invisible specks of bacteria on an orange, and the feeble lights of kebab shops and supermarkets failed utterly to register on the infinities of space above.

If it weren't for God, the almighty vacuum would be too crushing to endure, but once God was with you, it was a different story.

A star is also a delicate balancing act between the force of gravity, which tends to crush the star into oblivion, and the nuclear force, which tends to blow the star apart with the force of trillions of hydrogen bombs. A star then matures and ages as it exhausts its nuclear fuel.

A quantum theory of gravity that unites it with the other forces is the Holy Grail of physics.

Since the speed of light squared (c^2) is an astronomically large number, a small amount of matter can release a vast amount of energy. Locked within the smallest particles of matter is a storehouse of energy, more than 1 million times the energy released in a chemical explosion. Matter, in some sense, can be seen as an almost inexhaustible storehouse of energy; that is, matter is condensed energy.
