During the first trillion-trillion-trillionth of a second, matter and antimatter flickered in and out of existence. The fate of the universe hung precariously in the balance, it might grow, or it might collapse back into nothingness. Suddenly it ballooned to enormous size (after all, we are here), in what cosmologists call the inflationary epoch, bringing the first true particles of matter — the quarks — into existence. Within a millionth of a second the rapid swelling ceased, and the quarks began to be confined to protons, neutrons and electrons. The universe continued to expand and cool, but now at a more stately pace. Already the universe was vastly larger than what we are able to observe today. Within a few more minutes, protons and neutrons combined into the first atomic nuclei — hydrogen and helium — but still the universe was too hot for the nuclei to shag electrons and make atoms. Not until 300,000 years after the beginning did the first atoms appear.
Irregularities in the gassy universe of hydrogen and helium were accentuated by gravity. Within a billion years after the beginning, the first stars and galaxies were born. There were not yet any Earthlike planets orbiting the stars of the earliest galaxies, because there were not yet significant quantities of the heavy elements (these would be cooked up later in stars). Nor had the Sun yet been born. But within a few billion years, the universe had begun to look familiar on the largest scale.

okay lets say that big bang was a little dot that was swirling around and exploded. You all have heard of conservation of angular momentum.
ReplyDeleteSo if the universe started with a spinning little dot that spun clockwise and then exploded. Shouldnt evrything spin the same way? so why is Uranus,Venus and possibly pluto rotating backwards?Plus 8 of 91 moons spinning backwards?
Where does it say that the dot was swirling or spinning? Also, it may be very difficult to understand for you but the fact is that the universe is not the same as our solar system! The planets of our solar system did not form in the big bang. They formed about 5 billion years ago from the accretion of swirling dust and debris after the formation of the central sun. This has nothing to do with the big bang.
ReplyDeleteThe way the planets move have nothing to do with the Big Bang. But the fact that they exist certainly does have everything to do with it.
ReplyDeleteI don't understand how all matter including galaxies which take up large amounts of space came from an infinitely small dot which took up no space without the creation of new matter being included from an outside source
