View Full Version : Discussion: Audio: Unlikely Wormholes

2005-May-24, 04:59 AM
SUMMARY: Wormholes are a mainstay in science fiction, providing our heroes with a quick and easy way to instantly travel around the Universe. Enter a wormhole near the Earth and you come out on the other side of the galaxy. Even though science fiction made them popular, wormholes had their origins in science - distorting spacetime like this was theoretically possible. But according to Dr. Stephen Hsu from the University of Oregon building a wormhole is probably impossible.

wormwholes science fiction or fact its hard to tell, i support the science fact side of this arguent but instead of taking you to the other side of the universe they might take you to a neighbouring plannet. <_< <_< <_< <_< <_< <_<

Even then they might have their uses.

Hsu and Buniy&#39;s paper can be found here;
http://citebase.eprints.org/cgi-bin/citati...:hep-th/0502203 (http://citebase.eprints.org/cgi-bin/citations?id=oai:arXiv.org:hep-th/0502203)

they seem to be discussing negative, or exotic matter, which is apparently unstable;
there may be a glimmer of hope in the fact that very recent wormhole concepts use negative energy as opposed to negative matter.

If such a thing as a negative energy cosmic string were possible it would make the construction and stabilisation of wormholes somewhat less challenging;

but there is no indication yet that these entities are possible.

I&#39;ll ask the boffins on OA if there are any loopholes in these wormholes...

That was me in the previous post, by the way.

I am not sure that wormholes would be possible, but they could explain one or two things about the Fermi Paradox. Using tiny wormholes to communicate would avoid the need for powerful interstellar radio broadcasts in a galactic civilisation; it might also be possible to use wormholes for transport and avoid the need for detectable spacecraft (and high- powered drive signatures) between the stars.

Way to go Fraser&#33; A direct interview no less. I came to see if the story had posted after reading it in the BBC website (http://news.bbc.co.uk/2/hi/science/nature/4564477.stm).

Frankly, I never was much of a fan of wormholes, fact or fiction. If it was a natural event then it indicated an instability that could crash down on someone. If it was &#39;made&#39; then I might find the &#39;worm&#39; that made it only to be discarded in its garbage or maybe had for dinner. :rolleyes:

I&#39;ve been often amused, however, at the wormhole concept in fiction, it often seemed too much like a story of a girl named Alice following a crazy rabbit. :D

I remember 4 years ago there was a study that was going to take place.. into gravitation, into the origion of gravity and constract of matter that was put hold due to the reconstruction of the new Europian Partical accelaretor..

Does anyone have info on the subject if so please help.

WORM HOLE&#39;S&#33; Traveling faster than the speed of Light is the 4th Dimension, and the 4th dimension is the worm hole, as you are speeding through matter, and not going around matter. As you slow down from the Speed of Light you return to normal space that the matter exits in. The DISTANCE in time that you travel in the 4tjh dimension will determine the length of the worm hole.
I know the Theory that you can not go faster than the speed of Light. But there are magnetic field&#39;s that go faster than the Speed of Light
But pays attention to past theories. Since we are coming up with new ones to replace the old one&#39;s.
