The Big Bang
What Scientist Think The Big Bang Might of Looked Like.
The Big Bang is a theory that scientists thought that created the universe. Scientists believe it happened about 13 billion years ago, with every last bit of energy crammed into a speck. The extremely tight point exploded with a force that was unimaginable. The Big Bang was like no explosion you might ever witness in your lifetime. The Big Bang did not expand through anything, scientists believe that the Big Bang created and stretched space itself causing the universe to expand. In the first few minutes of the explosion the universe was billions and billions of degrees hotter than anywhere in the universe today. Before the atoms and particles could create anything, they had to cool down because they were far too hot to create planets and stars. Rapid cooling allowed matter to form in the universe. About 1 billion years after the explosion, gravity caused atoms to gather into a big cloud of gas and dust. There have been some questioning because of the Big Bang: Will the universe continue expanding? Or will gravity stop the expansion and we go back in time back to the speck that we started as? Scientists still don’t know the answer to these questions, but some experiments with the accelerator studies at CERN may offer some clues later on.
