What is past the Universe?
Question Date: 2007-02-27
Answer 1:

It is not really known what was here before the universe began. It is believed that the universe began about 15 BILLION years ago (a very long time ago) through a process called the "Big Bang" which says that the universe was initially compacted into a very small space and developed enough energy (heat) to "explode" causing everything to spread out. Since then the universe has expanded and become cooler, making it a livable place for us! It is also not known if there is anything BEYOND the universe or whether it goes on forever. We have not been able to test that with the technology we have today. Perhaps you will grow up to be an astronomer and help answer some of these great questions about the universe!
