Read this (or just the first page, if you want).
Parallel Universes
This is something that I've always thought was a good possibility.
Here's an overview:
The Article wrote:Overview / Multiverses
- One of the many implications of recent cosmological observations is that the concept of parallel universes is no mere metaphor. Space appears to be infinite in size. If so, then somewhere out there, everything that is possible becomes real, no matter how improbable it is. Beyond the range of our telescopes are other regions of space that are identical to ours. Those regions are a type of parallel universe. Scientists can even calculate how distant these universes are, on average.
- And that is fairly solid physics. When cosmologists consider theories that are less well established, they conclude that other universes can have entirely different properties and laws of physics. The presence of those universes would explain various strange aspects of our own. It could even answer fundamental questions about the nature of time and the comprehensibility of the physical world.
Basically, there are infinative Universes with infinative possibilities. Since there are infinative, there are Universes exactly like ours, and some with minute differences.
Thoughts? Comments?

Oh how I wish I understood high level physics.

This is cool:
The Article wrote:LEVEL IV MULTIVERSE
The ultimate type of parallel universe opens up the full realm of possibility. Universes can differ not just in location, cosmological properties or quantum state but also in the laws of physics. Existing outside of space and time, they are almost impossible to visualize; the best one can do is to think of them abstractly, as static sculptures that represent the mathematical structure of the physical laws that govern them. For example, consider a simple universe: Earth, moon and sun, obeying Newton’s laws. To an objective observer, this universe looks like a circular ring (Earth’s orbit smeared out in time) wrapped in a braid (the moon’s orbit around Earth). Other shapes embody other laws of physics (a, b, c, d). This paradigm solves various problems concerning the foundations of physics.

Most of this article is way over my head. I'm going to print it and take it in to my physics teacher.

By the way, I didn't just find this on my own. It was in yesterday's Kurzweil newsletter.

"infinative" isn't a word. "Ifinitive" refers to verbs.
"Infinte" is what you're looking for.
PS: I get pesky when discussing physics.
PPS: Just so you know, one of the ramifications of infinite universes means there are infinite universes out there EXACTLY like ours. In every way, down to where individual atoms are located. Creepy, eh?

I was reading a book on mulitverses. I should find it and finish it

Whoops. Didn't know about that little error. Thanks.
[now that I think about it, I did know that, but just didn't know about it right then]
Yeah, that is really creepy.
Another weird thing to think about is that in infinite universes where the laws of physics are completely different.
And that there are infinite universes where the only difference is that earth exists in a different a time period. If we could somehow find these universes and travel to them, we could essentially travel forward and backwards in time. There are also theories, though, that if something is changed in one universe, it has the potential to affect infinite universes [including ours]. So, the time travel paradoxes still apply. On that note, a good book is Michael Crichton's "Timeline". Very good book working on these theories.

Bye bye topic, you're over my head.

So...if there are parralell universes...does that mean that there could be another me?

Infinite yous, infinite mes.

Hmmm. Makes me wonder what "the other me" is like

There would be infinite exactly like you.
And infinite with the same slight differences.
And infinite with the same major differences.
Infinity is a mind-boggling concept.

imagine getting paid just to sit there and think up these theories? How can you be wrong?

1. The universe is explicable (it can be explained).
2. The laws of physics are the same everywhere.
3. ONLY ONE UNIVERSE!
4. Observations not experiments.
5. The universe is dynamic.
That was the first five minutes of my astronomy class. (Note: the punctuation I put is the punctuation he used.)my astro prof again wrote:There are no such thing as paralell universes. They make good science fiction, but are wrong.
Even if these parallel universes did, by some stretch of the imagination, exist we would not be able to travel there. The article claims they are beyond the range of our telescopes. The most distant thing known currently is a quasar at about 15 billion light years from us. Plus there's no way we could build a telescope that could go anywhere near the speed of light. (Btw, wormholes don't work either.)

Christa, let's be realistic... if you had the delorian from back to the future, we both know it wouldn't be that difficult!
