Re: Imagining the tenth dimension
 

My friend once told me that you, in theory, can travel in time..
He did try to explain how too, but naturally I didn't really understand.

Interesting. Nevertheless 99.9999% of humanity doesn't even really get along positively with their 4 dimensions, so...

saw this many years ago. even posted it here more than ½ a year ago.

I think you are wrong on this, and I think you are wrong about the power issue. For 2 reasons. Its all theoretical anyway and I'll allow you to disprove travel to the past, once you can prove travel into the future. Typical of most scientists and self proclaimed geeks (of which I am one!) If we cant do, or even prove something, it's because we weren't powerful enough, hence your comment on "not enough power" :D

Read Fabric of the Cosmos, and you'll think differently;)

And Archi, the basic principle is that you can't travel back past when you first open the wormhole. If you open the wormhole, you could miss where you're trying to hit, and end up somewhere else, and you can travel back in time to where you started out, or after, but not before when you create the wormhole.

This thread makes me wiggle and giggle.

If I throw a rock threw the hole will it hit someone?

Re: Imagining the tenth dimension
 

I wasn't disagreeing with your post Mudra, I was just giving an example of why "going back in time" like in Back to the Future never really struck me as realistic. However, only being able to return to the point where you first opened the wormhole seems much more plausible.

Have you seen that movie Primer? It's a twisty, convoluted film that makes you think, and uses a similar concept. Definitely worth checking out.

Talk to the guy Colbert always has on his show, what's his name...? The black guy. Well anyway, he describes wormholes and yes einstein proved that they are therotically a possibility. If you ever read the book 2001: A Space Oddysey, it is fiction. But the aspect of traveling through a worm hole like he does in the book is grounded in scientific theories. We know worm holes exist, that is fact, it's just a matter of if we can exploit them to travel through them. The problem with a worm hole is that by approaching the speed of light, you get heavier and more dense, to the point where you can't be that dense, and thus you can't make it through, it's all very mumbo jumbo, but I believe sometime we'll do it. Let's just hope we dont end up in the middle of some cluster fuck of a star
