A few weeks ago Hanners, Suze and I were talking about space and time <yes, we do talk about some strange things>, and Hanners mentioned that she had heard some scientist on the radio talking about how spacetime was curved. That struck me as interesting and significant idea, so it stuck in my head. Then, on this thread http://www.collarchat.com/m_3800352/tm.htm somebody asked what had happened before the Big Bang and I had this sudden crazy idea.

We know that the universe is expanding, and if you travel away from a point along a curved path, you will eventually end up where you began. So maybe, the universe expands until it curves back in on itself and collapses into the singularity thus causing a new Big Bang. That’s not my crazy idea; I’ve heard that idea before somewhere or other.

My idea is that if time is curved as well, then the universe will eventually come around to when it began as well. So what was before the Big Bang was the universe. Not a different universe, but this one. There is only one Big Bang, only one universe, happening over and over again on a loop. Sort of like a cosmic Groundhog Day

This brings up all sorts of interesting ideas and questions, like “Does it repeat itself exactly, or is it different each time?” and “Have I existed before?”

Now you know why I don’t need to do drugs. [:D]

So, what do you think about my crazy idea?
