This video has nice visuals from Science Loop. Many have wondered about how did the entire Universe start. Watch the time lapse of Entire Universe with cool visuals. The entire timeline of the universe (13.8 B Years) is explained here. Watch the descriptions from the Big-Bang to the Present. See primordial clouds and our sun. See the supernova explosion and the formation of the black-hole. See how the universe goes from collision to formation. See the Rise of life. It is interesting Extream Animation, VFX, SFX. Headphones can be used for a better experience. Subtitles are available.
As many people know, The Big Bang Theory says that our universe was born about 13.7 billion years ago in a massive expansion that blew space up like a gigantic balloon. Almost all cosmologists and theoretical physicists endorse this fascinating theory. There seems to be convincing evidence supporting this idea.
The universe took shape in an amazing way.
Cosmologists think that there are 4 forces that rule the universe:
1) gravity
2) electromagnetism
3) weak nuclear forces
4) strong nuclear forces
Cosmologists suspect that these 4 forces were unified into a single force at the universe's birth. They were squished together because of the extreme temperatures and densities involved. Things certainly changed as the universe expanded and cooled. Around the time of inflation, the strong force likely became separated. At about 10 trillionths of a second after the Big Bang, the electromagnetic and weak forces became distinct, also.
Just after inflation, the universe was probably filled with a hot and dense plasma. But by around 1 microsecond, it had cooled enough to allow the first protons and neutrons to form (researchers think). In the first 3 minutes after the Big Bang, these protons and neutrons began fusing together, forming deuterium (also known as heavy hydrogen). Deuterium atoms then joined up with each other, forming helium-4.
Yes, all this sounds very complicated. Over time, stars gravitated together to form galaxies. This lead to more and more large-scale structure in the universe. Planets coalesced around some newly forming stars (including our own sun). It seems that 3.8 billion years ago, life took root on Earth.

ReplyDeleteThanks, Science Loop, for a cool video about the entire universe. Most people think that the universe began with an explosion of space itself - "the Big Bang." Starting from very high density and temperature, space expanded and the universe cooled. The simplest elements formed. Amazingly, gravity gradually drew matter together to form the first stars and the first galaxies.
