Wormhole Travel impossible?

[JF060392]

in order to travel through a wormhole u need to keep it open, once that is done you proceed, one problem remains u have no control over where u will end up. you cant control the out put of wormholes thus making the destination's completly random depending on the hole. we would have to engineer a device to control and create wormhole outputs. can we do it???:sun::moon::shocked:

We don't know. At the moment it is an open question. If you know what to look for you can find quite a few recent research papers on this (they rarely use the word "wormhole" in the papers).

However, note that the question is if we can do it in PRINCIPLE; not if it can be done in the near future. We know that we would need an enormous amount of energy and we have no idea about what kind of technology it would require. Maybe in a few hundred years or so if we are still around.

In my GR class we heard a talk on worm holes. While they can theoretically exist, ANY perturbation to them causes them to collapse. So basically even observing a wormhole destroys it.

Not neccesarily, it might be possible to stabilize them. Apparantly there was a paper about this in PRL a few weeks ago (I haven't read it myself, I seriously doubt I would understand anything if I tried).

they do it on tv all the time!

Ah. Well I took the GR class a year and a half ago so things may have changed since.

I thought a wormhole could be a black hole,and they are open.
I bet black holes lead to another whole new universe.Where does the stuff go?
We dont see in space a place where all this stuff black holes eats just pop out.
So wormholes like star trek dont seem right,becuase they are always sucking in.
And we would see this happen in space,stuff just flying out of nothing.
So we live in the outer-verse,and black holes lead to the inner-verse.

it leads to heaven. no im kidding. Jesus is the Way.

According to Stephen Hawkings, the greatest mind we have living today, Black Holes steadily 'evaporate' via quantum dissipation and likely don't eject matter into another universe. They just slowly fade away an atom at a time.

Wormholes in theory would be too unstable and likely too small to be significant. Membrane/string theory is where it's all at.

The problem with talking about wormholes is that nobody knows or has any proof that they even exist. All there is are a number of theories whose mathematics allow for what are what collectively called wormholes. The wormhole in one theory might have completely different or contradictary properties to one in another theory. Since none of the theories have been proven yet it may turn out that they may all be wrong. In the end wormholes may not exist in any form in the real world.

Also known as Hawking Radiation.

The real Universe cares nothing about what theory sounds the neatest. It is only what it is. I thought this was supposed to be a highly technical forum? If you just want to discuss science fiction and ignore science fact then I am sorry I ruined your fantasy.

Just a thought.. suppose we could create wormholes, even unstable ones where we wouldn't necessarily know the location at the other end. It wouldn't be complete failure as we could launch space probes out into the universe to look for intelligent life or other interesting feature along with contact info for ourselves. Just because we can't bridge the vast distances in space(for a return trip) doesn't mean someone (or something) else hasn't figured it out.

Edit: And even if some *other* civilization couldn't get to us or reply in some fashion, at least we'd be letting some other civilization know that they're not alone in the universe, thus answering the same question for them that we currently have.

Have you learned nothing from the Sci-Fi channel:

Any alien species we contacted would then know we exist and immidiately dispatch their fleet with the intention of enslaving our race.

I do not forsee an answer, in my lifetime, to whether "wormhole travel" is possible. Their is so much we don't know, and probably an equal amount that we think we know, but are wrong.

I remember a few years back reading a paper on negative energy (I think they referred to it as Ghost radiation??? . In any case, it only exists in some theories), and I read a magazine article a few months later about it could (once again theoretically) be used to stabilize a wormhole.

So in some theoretical models, it is possible. Even if it is possible, however, how would we generate enough energy to actually do it?

Either everyone here is a Hawking and I don't belong, or you guys need to start assuming less and stating and proving stuff more. What is a wormhole anyway?

Where does the stuff go? It sits there. A black hole is a very large collection of matter, where the escape velocity has exceeded the speed of light.

And there can't be a point where the matter from black holes "pop" out. The concept is called White Holes (IIRC), where the matter and energy sucked in through black holes reappear. The problem with this is that the matter which formed the black hole and any other matter coming through will reappear at the white hole, and then clump together again due to gravity. Eventually so much matter will accumulate that the white hole collapses and becomes a black hole again.

But since our universe does not consist entirely of black holes, yet, I don't think the existance of white holes is plausible.

Yep... squeezed vacuum tech will do it. Only for comm and energy transfer though - won't be able to get them big enough for object transport.

A wormhole is like an asshole. But unlike an asshole, the wormhole don't put out ******. In some Sci-Fi movie it shows the wormhole sucks when something come close to it while other shows it like a ternal and objects just enter and/or exit it.

Now wormhole and black hole. Black hole might be a 1 way street to hell or somewhere (hell being out of existence). And wormhole is said to be stable and you won't get distroy or kill in, entering or exiting it.

Anyway, jumping to conclusion. We haven't got a clue what we're talking about because none of this 'wormhole' is seen or proven or ANYTHING.

Edit: Along this idea, there are: subspace travel, worp speed (however you spell it), light speed, inter-dimensional travel.

Anyway the only thing I have to worry about in my travel is speeding ticket which limit me to 55mph.

Just dial up Atlantis and ask the acients how they did it. :laugh:
