You were talking about Futurama, I know. The second paragraph was unrelated.

So am I. What does that have to do with disliking Futurama?

I thought we were talking about wormholes?

Oh right. In which case wormholes are designed to move people between the curve of space and hence long distances.

There's also something else called hyperspace but I think that's more science fiction than fact.

That's why it seems possible to use wormholes to travel quickly through space. Unrelated - does anyone know any good Futurama forums?

Ok this is getting a bit out of hand. I thought saying that would stop you guys, I guess not.

aside from futurama, is it possible that you could use darkmatter for any type of travel since they say that darkmatter is in space and everywhere

Darkmatter apparently distorts the universe, which is why the universe is expanding, so I guess it's at least one of those matters that could be used for space travel.

yeah, hopefully, one day we figure out how to use it, and it will make it easy and fast to travel through space

dark matter, heres what we know:

- nothing

heres what we think:

- We think theres a lot of it
- We think its a WIMP (weakly interacting massive particles)
- We think it absorbs EM radiation
- We think it makes up the un accredited mass of galaxies, i.e when you look at a galaxy over a period of time you notice it rotates, therefore it should obey simple newtonian physics (planets do so why shouldnt galaxies?), so you can calculate its total mass from its time period of rotation, lets call it x.
Now we estimate the amount of stars in that system, look at thier relative brightness and luminosity and with some fancy programmes and calculations we can estimate the mass of the galaxy that way, lets call this one y.

Guess what? x is much much much bigger than y and we can't find anything that will explain this extra mass. (im not talking about standard error out either, im talking about around five times more mass!!!)

So we don't know what extra mass is so we called it dark matter, as always heres a link for futher reading if your interested:

oh and crytek thats dark energy:
http://en.wikipedia.org/wiki/Dark_energy

Thanks
I'd seen some show on the history channel, but this makes more sense than that.

Ah, dark energy, that's it. You can see why I get confused.

And I've read a book about this type of thing in a Doctor Who book, trying to explain how Doctor Who can be related to real science. I've also watched The Universe on The History channel.

What is exotic energy/matter? What's the difference between dark and exotic?

Does EM stand for Electro Magnetic?

yes EM means electromagnetic

now crytek my knoledge on exotic particles is very skectchy and I haven't even heard of exotic energy! However this has intrigued me and when I get some time i'll try and do some research into it.

But to my knoledge exotic particles could mean one of two things:

1) particles that do not operate under standard laws of physics or
2) particles that are oddly composed

like instead of having the normal proton electron configuration they could have a proton and something called a muon (like a big electron) pair.

I like going with 1. Particles that aren't affected and don't abide by the laws of physics

"Exotic matter is a hypothetical concept of particle physics. It covers any material which violates one or more energy conditions or is not made of known baryonic particles. Such materials would possess qualities like negative mass or being repelled rather than attracted by gravity. It is used in certain speculative theories, such as on the construction of wormholes. The closest known real representative of exotic matter is a region of pseudo-negative pressure density produced by the Casimir effect."

I remember reading about matter that works the other way around in that book. I think exotic energy is simply negative energy, which is coupled with exotic matter.

It seems exotic matter is the type of thing that would fuel warp drives and wormholes because it acts differently on the universe, causing space distortion.
