n Physicist Identifies How to Find Wormhole: Look For The Light

Portals to parallel universes or far off regions of our own cosmos may be found if astronomers know where and how to look, a Russian physicist claims. Wormholes to other worlds can be recognized by the unusual way they bend light, according to Dr Alexander Shatskiy, from the Lebedev Physical Institute in Moscow.

He believes more powerful space telescopes will be able to look for wormholes in the centers of large galaxies. Wormholes are said to link different regions of space, or even different parallel universes. Anything entering one end of a wormhole would instantly appear at the other end, so long as the tunnel could be kept propped open.

Although scientists have seen no direct evidence of wormholes in the universe, it may be because they are disguised as black holes. Dr Shatskiy believes there is one sure way to tell the two kinds of object apart.

Wormholes would have to be kept open by a so-far unidentified material with bizarre properties. This substance, known as "phantom matter", would have negative energy and negative mass, causing it to exert a repulsive effect.

Dr Shatskiy's calculations indicate that as well as "opening the door" phantom matter would deflect light, providing a useful wormhole signature. Because of phantom matter, any light emerging from a wormhole would diverge to form a bright ring. Any stars behind it would shine through the middle of the circle.

US expert Dr Lawrence Krauss, from Case Western Reserve University in Cleveland, Ohio, points out that the idea, while fascinating, rests on assumptions that have not yet been tested.

Krauss told New Scientist magazine: "It is an interesting attempt to actually think of what a real signature for a wormhole would be, but it is more hypothetical than observational. Without any idea of what phantom matter is and its possible interactions with light, it is not clear one can provide a general argument."

However, it is commonly accepted that wormholes are possible within the framework of general relativity. In fact, their existence would certainly help make sense of some current paradoxes in the world of physics. Although folding space has yet to be documented, there continues to be a healthy debate in the scientific community about their existence. Stephen Hawking gave a lecture, which discussed the possibility of wormholes in folding space. The implications of human travel through these wormholes could result in “short-cutting” through vast distances and even time itself.

According to this idea, one could even move faster than the speed of light.  Professor Hawking puts it this way, “If you can travel from one side of the galaxy, to the other, in a week or two, you could go back through another wormhole, and arrive back before you set out.”

While a bit unfathomable, a similar type of “time travel” has already been demonstrated.  Scientists who studied passengers on space shuttles have found that, because of the shuttle’s high speed, time moved more slowly for those on board.

So, what is a wormhole? Simply put, “masses that place pressure on different parts of the universe could eventually come together to form a tunnel.” Wormholes are also referred to as “Einstein-Rosen bridges”, and are related to Einstein’s theory of special relativity, and the space-time continuum. If wormholes are proven to exist, the possibilities will be literally endless.

Fan of the first session TV series the sliders
The idea of portals to parallel universes was once explored by one of my favourite science fiction TV series the sliders.

Inspired by the series I thought I could be able to duplicate Quinn Mallory's antigravity experiment researching what I could find out on the theme.

It was't long before I discovered parallell universes could only be acesesed by wormholes created in the centre of black holes artificial ones created by an antigravity experiment in a basement here on earth as Mallory's antigravity expeiment did in the sliders.

The whole colection of my resulting files since 1999 isrecently published to a blog I called time travel and parallel universe theories .blgspot.com. coming to the conclusion aceses to paralle universes much less time travel is mathematically impossible to acheiove a working blue plane for a working prototype of Quinn Mallory's antigravity experiment.
