Trent--BIGGGGGGGGGGGGGGG+BANGGGGGGGGGGGGGGGGGGGGGGGGG

The big bang is what was believed to happen in the beginning of time to start the universe. It is believed that the expansion started 13.3 to 13.9 billion years ago, and the universe is still expanding today. There was an infinite amount of density and temperature at a time in the past. All that caused a massive explosion with the universe rapidly expanding and cooling. Over time all the matter in the universe developed into groups of it and slowly molded together to form the planets and the stars.
