Whuat?!

Re: Imagining the tenth dimension
 

It starts talking nonsense at the 5th dimension. :p

Re: Imagining the tenth dimension
 

I had a tiny little lol at Flatlanders.

Re: Imagining the tenth dimension
 

Eh?

Re: Imagining the tenth dimension
 

Obviously he was wrong about the 2nd dimension flatlander's part, because Paper Mario isn't split into two by his oesophagus.

Nice video :)

Re: Imagining the tenth dimension
 

Wait wut??

Didn't we establish/proven already that time travel is impossible?

However if this theory is correct then space travel would be possible. You don't have to go faster than the speed of light, you could just fold the space/time continuum and travel instantly to the other point.

Only hope is, we won't meet hell like in the movey event horizon =p.

Re: Imagining the tenth dimension
 

Time travel is possible into the future. However, you can't go back in time farther then where you started from when traveling into the future. And of course, the sheer amount of power that would be needed to open the wormhole, make sure its at the right spots, and open it wide enough and for long enough to pass through and come back later are astronomical, and beyond our tech right now. Also, yes, this stuff is mostly correct, it stems from string theory, which is mathematically completely proven, but still untested experimentally due to us lacking the tech to do so. However, it is the new supercollider in Switzerland that could yield the first proofs. See, string theory says there are 11 dimensions, and gravitons, the particles that create gravity, are multidimensional in their ability to affect matter, but single dimensional in where they reside. It is believed that by using the LHC, we can pull those particles into our demijohns, at least temporarily, long enough to see them. If we can do this, it is a MAJOR proof of string theory.

Check out the book and documentary "The Elegant Universe" and the sequel to the book "The Fabric of the Cosmos."



Here's a better visualization:

Each of those points would actually be on every single point, which are infinite, of course. Curled up into each point are the extra dimensions, in which other particles, gravitons included, reside. We pass through these dimensions every day, every time we move, but we don't actually feel it, as they are so minuscule.

Thanks for posting this, bookmarked his site, hours of head scratching ahead! :)

Re: Imagining the tenth dimension
 

I did know, it was possible to travel into the future, theoretical. Never knew much about the string theory (i never was a big fan about the shear amount of dimensions needed, but in way it makes sense).

I always thought that the whole search for the gravition was to unify all the basic forces in nature, in which gravity always was an exeception, into one theory. To prove that even gravity is driven by subatomic particle interaction.

Re: Imagining the tenth dimension
 

Actually, the problem with unified field theory was that you've got quantum mechanics, and general relativity. The former deals with small stuff, and later with big stuff (big stuff being anything above the quantum level). The problem is, when you try to unify the mathematics and theories, it doesn't work. String theory brings in the extra math and models that are needed to unify it, which is does perfectly. The problem is experimentation on it, which we are getting closer and closer to being able to do.

Re: Imagining the tenth dimension
 

I watched this video a few weeks back. I see the way it strings it all together and makes logical jumps to get to the next dimension. It actually helped me understand alot about it, yet more or less pointed out what I cannot comprehend!

VM, the human race knows nothing of any real value about the mechanics of time travel, why are you assuming that it would require vast amounts of power? Maybe it is something simple.

Re: Imagining the tenth dimension
 

Because your talking about literally bending spacetime back on itself. A wormhole is essentially a black hole that has a beginning and end that don't involve gravity. Take a piece of paper, and fold it in half. Now put a hole through both halves. THat's what a wormhole does. The calculations have been done on it, and it is astronomical the resources needed for it. Read The Fabric of the Cosmos, it has a whole explanation on this :P

Re: Imagining the tenth dimension
 

That explanation, at least to the 4th dimension part, is based on this awesome video of Carl Sagan.

Re: Imagining the tenth dimension
 

Saw this on his site a while ago, and really liked its explanation of these concepts. However, I have always had a problem with the whole "time travel" concept because, what if you were to go back in time, and give yourself a locket or some object. Then, that you lives his life until he goes back in time and gives it to himself again.

Where did the locket come from? It is essentially creating something from nothing. It works the same way with information. If you went back in time and told yourself how to build a perfect computer or something, who invented it?

The only way time travel would work is if you were to splinter off into a symmetrical parallel universe.

Re: Imagining the tenth dimension
 

No no, you're not understanding. You can't travel back in time, only forward.

Re: Imagining the tenth dimension
 

Actually Mudra it is considered possible to go back in time by jumping through a wormhole. It is speculated that you can reach the speed of light by doing so, and if you manage to survive, surpassing the speed of light will send you so fast forward in time, you'll end up behind where you are about to be, thus, back in time.

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.

Re: Imagining the tenth dimension
 

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

Re: Imagining the tenth dimension
 

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

Re: Imagining the tenth dimension
 

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

Re: Imagining the tenth dimension
 

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.

Re: Imagining the tenth dimension
 

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.

Re: Imagining the tenth dimension
 

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

Or worse....

I'll have to cut time a new hole with my knife!

It's a 'shop; I can tell from the pixels and having seen many 'shops in my time.

Seriously though, good movie/series. I remember watching these videos on their website a year or two ago, very informative.
