Everything happened after the big bang.
The big bang theory has nothing to do with the formation of planets.
It all started with the Big Bang. All the matter created from the Big Bang eventually formed planets and every thing else. From the moment matter was created during the Big Bang the matter was expanding and moving really fast. So eventually all the planets and stars and galaxies that were formed started to spin around each other from the velocity that was created.
It started with the big bang. This created the stars and planets
Probably several tens to hundreds of millions of years following the Big bang. Afterwards, planets formed around stars and became a permanent feature of the Universe.
No elements were formed in the big bang. After quite some time, hydrogen began to form, and it is the main constituent of stars. The main by-product of nuclear fusion in stars is helium.
well there is a fact that you need to know here , the big bang formed the whole universe we observe nowadays and as the great astronaut carl sagan said " what happened before the big bang is not affected with what happened after the big bang " so we might never know .
Neptune came from the big bang like the rest of the planets it was formed by all of the gasses that were let off when the big bang happened.
Without the Big Bang there would be NOTHING. The entire Universe - including space, and apparently even time! - is the result of the Big Bang.
There was a big bang.. then space came with lovely stars but there was no planets.. when alot of rocks formed together another big bang had come and made.. EARTH!
If the big-bang theory is true, the stars, planets, and other universal bodies were progressively formed, so there were much less stars than we have today, and the fomation of new stars is compensated by the death of others.
Hmph. The Big Bang theory did not form the sun. The big bang formed the elements hydrogen, then hydrogen began to create helium. Then stars were formed out of these two elements and that is how our sun was created.
Scientists "speculate" that the Big Bang created antimatter, but it was destroyed when coming into contact with stars, planets, and other matter.
