Forget Black Holes, How Do You Find A Wormhole?
Written by Ian O'Neill
Finding
a black hole is an easy task? compared with searching for a wormhole. Suspected
black holes have a massive gravitational effect on planets, stars and even
galaxies, generating radiation, producing jets and accretion disks. Black holes
will even bend
light through gravitational lensing. Now, try finding a wormhole? Any
ideas? Well, a Russian researcher thinks he has found an answer, but a
highly sensitive radio telescope plus a truckload of patience (I'd imagine) is
needed to find a special wormhole signature?
Wormholes
are a valid consequence of Einstein's general relativity view on the universe. A
wormhole, in theory, acts as a shortcut or tunnel through space and time. There
are several versions on the same theme (i.e. wormholes may link
different universes; they may link the two separate locations in the
same universe; they may even link black and white holes together), but
the physics is similar, wormholes create a link two locations in space-time,
bypassing normal three dimensional travel through space. Also, it is theorized,
that matter can travel through some wormholes fuelling sci-fi stories like in
the film Stargate or Star Trek: Deep Space Nine. If wormholes
do exist however, it is highly unlikely that you'll find a handy key to open the
mouth of a wormhole in your back yard, they are likely to be very elusive and
you'll probably need some specialist equipment to travel through them (although
this will be virtually impossible).
Alexander Shatskiy, from the Lebedev Physical
Institute in Moscow, has an idea how these wormholes may be observed. For a
start, they can be distinguished from black holes, as wormhole mouths
do not have an event horizon. Secondly, if matter could possibly travel through
wormholes, light certainly can, but the light emitted will have a characteristic
angular intensity distribution. If we were viewing a wormhole's mouth, we would
be witness to a circle, resembling a bubble, with intense light radiating from
the inside "rim". Looking toward the center, we would notice the light sharply
dim. At the center we would notice no light, but we would see right through the
mouth of the wormhole and see stars (from our side of the universe) shining
straight through.
For the possibility to observe the wormhole mouth, sufficiently advanced radio interferometers would be required to look deep into the extreme environments of galactic cores to distinguish this exotic cosmic ghost from its black hole counterpart.
However, just because wormholes are possible does not mean they do exist. They could simply be the mathematical leftovers of general relativity. And even if they do exist, they are likely to be highly unstable, so any possibility of traveling through time and space will be short lived. Besides, the radiation passing through will be extremely blueshifted, so expect to burn up very quickly. Don't pack your bags quite yet?

Its nice to know that mankind has finally decided to challenge the impossible.Cosmologists were obssesd with black holes while they were ignoring and even questioning the existance of Wormholes.Its time to take the existance of wormholes seriously.Their effects on the galaxy and the expanding universe cannot be ignored.

I think worm hole does exist because there must be a back door or alternative door to a different dimension, maybe our dreams that we have all night is actually the events that is happening in the other dimensions?.well so the question is now how to hunt this holes..?

"maybe our dreams that we have all night is actually the events that is happening in the other dimensions"
Don't be so naive. Dreams have nothing to do with worm holes. Dreams are just results of the brain working overtime?because the only time the brain takes a rest, is when we're dead.
I do think there might be some possibility of the existence of wormholes, but they could also be a mathematical leftover, just like it is mentioned in the article.

There are many wormholes like black holes we know they exit in our universe and there are many other dimensions ,other dimensions feed our universe with energy and our universe feed the other dimensions if one universe become to big it will float over in a empty place between this dimensions and a new universe will be born there was never a big boom like science may say a new universe it start throughout a door point maybe throughout a black hole or a wormhole ,energy will float over and build a new universe also a old universe will become empty It be a eternal living circle,
Be it divine I think so someone or something must have started it Eternity have no time .Science says billions of years our universe started but where it came from?Atheist say
it all be a mechanical evolution but whom or what let it grow, change and develop that way .

Are we so smart that we cannot fathom the thought of some alien civilization, millions of years ahead of us, possessing the capabilities to make use of a wormhole? I surely hope not.
January 22nd, 2008 at 3:48 am
? OOOhhhhhhhhhhhhooooooooooooooooooooooooooooooooooooooooooooooooooo!!!!!
January 22nd, 2008 at 3:52 am
What's that sound? Du'no? but sounds like a "screaming banchee"? "Whoooa pilgrim get a grip on yer' whiskey glass, before you a'searching fer a wormhole?"
January 22nd, 2008 at 5:56 am
I've discovered a black hole?.It resides in Chrix's head.

If light is transmitted through a wormhole, and we can see stars in the centre, as explained in the article, that means the light is transmitted in an "orderly fashion", meaning that the light is not scattered. Scattering of light renders it impossible ro recreate an image on the other side. But if it is true, then matter (at least seperate atoms or molecules) could very well also be transported in an "orderly fashion". Now as a Stargate Fan, i know that in the series they postulate that matter passing through the artificial "event horizon" of the stargate is broken down into a matterstream and transmitted through the wormhole, and recontructed on the other side. Also quatum state and velocity and direction are encoded in the matterstream. I know this is something deemed impossible by scientists at present, but who knows we just may be able to control all these things a a few eons from now. After all, who thought the roll-up screens in Earth:final conflict would be possible? well they are now?.

Forget blackholes & wormholes, there are none near enough for us to worry about? What we should be worrying about is mess we are making of earths atmosphere?
January 22nd, 2008 at 7:25 am
If light travels trhu a wormhole, surelly it wil be subject to a massive influence of gravity. In other words, similar to light in the neighbourhood of a blackhole, time will slow down, won't it? Does that mean that they could be doorways, or windows, to a distant time - past or future, depending on wich side of the hole we are?
January 22nd, 2008 at 7:34 am
We can't even leave Earth yet on a regular basis without something screwing up.
Sure NASA is filled with top minds, but if they made 136 million dollar error through faulty conversion?wtf.
Until there's an efficient and cost effective way to travel outside of our Earth, I seriously doubt we need to worry about wormholes.
I honestly think it would be cooler to look at the Earth from a distance within my life time, rather than find out in 50 years "We may have found a wormhole, but now we need the technology to make it out of Earth on a regular basis"
January 22nd, 2008 at 7:35 am
i think its cool we are finally breaking the mold of our current way of thinking and beliveing the universe is as easy as building blocks in a lego set. there are plenty of things out there we don't understand, and unfortunately i wont be around to understand them when we finally do. but being a star wars fan i would love to see some hyperspace travel, oh yea

Matthew and Richie, how about we all bury ourselves in our own mundane worries and forget astronomy altogether? Much better. Who needs to strive for something beyond the common experience? Please, we're on this site because we are interested in something grander, bigger than just our own personal experience.
And Dutchart, punctuation doesn't hurt. Please, don't bother writing if you can't be bothered to be understood.
I wish the article had included more information. How can you see stars through a wormhole that are on "our side". Aren't those just in front of the hole? What might generate a wormhole? Couldn't that just be another black hole? It obviously has to have a massive gravity well to unite two sides of an even bigger bend in space! And Freedman, you're right, if light comes through cohesively, then we should be able to reassemble matter even if it is stretched out first?afterall, didn't some physicist postulate that no information can be entirely lost? Maybe people will never go through, but maybe goods or probes?

Seems some of the people here need to learn to distinguish fantasy from reality.
The mathematical wormholes of general relativity bear scant relation to the wormholes in bad sci-fi like Star Trek or Stargate (which I enjoy watching as much as the next guy, but both shows have almost as many holes in their science as they do in their respective plots). Even more plausible efforts like Peter F. Hamilton's recent Commonwealth trilogy take considerable liberties I think.
I'd be as excited as anyone else if it turned out that we could use wormholes for transit, but I think in practice we're much more likely to be limited to real space. In sci-fi terms, the future may be much more Alastair Reynolds and much less Gene Roddenberry.
January 22nd, 2008 at 8:52 am
Worm holes? Maybe! More than likely not! I believe there are only four dimensions to deal with. It appears all else is fantasy. based on math aberrations.
January 22nd, 2008 at 9:30 am
Im all for the search for worm holes, but why not put money into something we know exists that can be attained in the next half century. There will be plenty of time to search for this if we don't kill overselves in the next 50 years.
January 22nd, 2008 at 9:32 am
Once upon a time, no one believed that black holes could exist either.
Then we looked for them.
We should not exclude the possibility. Mathematics predicts them, just as mathematic predicted black holes.
They may exist, they may not exist, but we should at least try to find out. Even if can never use them, they could be very valuable to science.
January 22nd, 2008 at 10:14 am
I have yet to see the math whereby anything w/rest mass can travel through a wormhole w/o causing it to collapse. Even a single atom or cosmic radiation will do the trick. Though they may mathematically exist, their existence is so short lived, they evolve quickly into black holes at the first sign of matter entering them. I seriously doubt we will find them just open and remaining open for any sustainable worthwhile time length.
January 22nd, 2008 at 10:42 am
Hmm. And what do we see if we look down into one of those jets coming from the poles of a supermassive black hole at the center of a galaxy, in the moment before the radiation obliterates us?
January 22nd, 2008 at 12:10 pm
[?] 20% time was about warm holes. I read an article called "Forget Black Holes, How Do You Find A Wormhole?", that was Written by Ian O'Neill. I reat it at Universe Today. It talked about warm [?]
January 22nd, 2008 at 12:54 pm
"Worm holes? Maybe! More than likely not! I believe there are only four dimensions to deal with. It appears all else is fantasy. based on math aberrations."
First of all, wormholes in general relativity do not need more than 4 dimensions, so your argument is illogical.
Secondly, belief is the death of science. Never believe, always doubt. Always question.
January 22nd, 2008 at 1:43 pm
You're saying I went through a wormhole and not a blackhole?
So many years? wasted.
January 22nd, 2008 at 2:11 pm
i have to agree with those who are saying that we should worry about things that most concern us, or atleat things that we can reach first and then exercise the rest of our availible time on these issues
January 22nd, 2008 at 2:40 pm
What was it 15 years ago they finally agreed that there might be black holes and now every galaxy has one at the center. Give wormholes a chance.
January 22nd, 2008 at 3:37 pm
I think most of the people who read this article think that we have other matters of importance than something as interestsing as a discovery of a wormhole.Maybe this kind of thinking is the reason for the slow technological progress of mankind as a species.We need to think out of the box.How long are we going to push such important things for future generations.Concidering the quantum leaps of technology and understanding of science in the last 18th and 19th century we are suppose to be at phase 1 in technological advancement but we are still at phase 0.If our species has to advance then we need to think radically.There is no such thing as Science-fiction.
January 22nd, 2008 at 4:33 pm
Nothing like mention of wormhole to bring out the LOONEYS
January 22nd, 2008 at 6:20 pm
Inside the boundaries of a black hole, time stops, and you'd need to shoot out of there at the speed of light to escape the gravity. You'd probably be surprised to discover that an eternity had passed out here, meantime, where time had been normally drifting by. The wormhole sounds like even more fun. You shoot through it and may end up standing on a concrete, six-lane highway in another universe where you collide with a jalopy that looks suspiciously like a 1936 Ford. The first thing you'd notice is that folks in that universe must have built fancy highways before they invented their Ford, because their Science knew what was coming. As our Science has evolved, we also know pretty much what's coming. The difference is that we want what's ours now, not tomorrow. ANy questions?
January 22nd, 2008 at 7:00 pm
I think that the technology required to pursue WormHoles may be deployed in much other enquiry and discovery. Good; and go for it!
I agree with Peter K's comments on the Earth-Onlyists and Dutchart; so do check your e-mails, or, perhaps better, get them checked by someone competent in English expression. Two minds can make something great of something second rate.
I wonder what relationship there will be found to be between WormHoles and WarmHoles and DarkMatter and DarkEnergy? Hmmm?
January 22nd, 2008 at 7:10 pm
Some of the folks on here must be from Afghanistan. Well, the earth is not flat and yes we should look for wormholes. This does not mean that we drop all other matters that concern us. It is not LOONEY to imagine and seek out new facts.
January 22nd, 2008 at 8:45 pm
Wormholes are how flying saucers are able to get to Texas.
January 23rd, 2008 at 3:13 am
These are nothing but hypothesis.This nothing but theoretical aspect of general theory.So we cannot call it as warm hole.It is also not possible whether this hole do exists
January 23rd, 2008 at 4:08 am
over the word fantasie and reality ,
What people that have lived a hunderd years ago must have thought about ,
planes ,flat tv , mobiel phone ,trip to the moon,new hart ,new growing cells and so on .
Yes all fantasie no reality where are we living? in the past?.
What about our earht !,nothing have changed some people like to believe us .
because it be all about money and oil the same with war.
so what be reality and what be fantasie

The fact that GR permits wormholes seems to me justification to look for them.
Also - it would make reading these comments a lot easier if the contributors would read them back and spell check them - correcting mistakes before hitting the 'Submit Comment' button.

REV, I will not destroy Earth. I just wanna have a little fun with Texas.
January 23rd, 2008 at 10:30 am
Perhaps the author would add today in back of the word impossible. There are hundreds if not thousands of things common today that were impossible just 20 years ago.
January 23rd, 2008 at 4:18 pm
General relativity, "black holes", "worm holes" and the hocus pocus "gravity" it predicts are lies on a scale that would make the Bush Administration blush.
January 23rd, 2008 at 4:56 pm
well this isnt about The Universe SRRY,but ive been here before.ANd still do:D um i was going to ask? if my tooth has a grayish color is it a root Canal??
just a question i hope its ok to say it here
January 24th, 2008 at 6:44 am
[?] me so, I nearly tripped over a hole in the street. Of course, it was a black hole at that, if not wormy ? tough to see in advance, even if you're lucky enough to spot a flicker from one. [?]
January 24th, 2008 at 3:32 pm
I knew it I just knew it George W isn't from Texas after all.
Though I didn't literally mean that wormholes brought out this looney.
January 25th, 2008 at 2:48 pm
That sounds brilliant, if you can actually see through to somewhere else in the universe.
