Do WORMHOLES really exist in space?

Question

and if they do, what exaclty is their purpose and what can we gain from them?

Answer 1

yes they do, if only for a short short time...
why time travel and teleportation (fun, fun, fun!!!), of course

Answer 2

There is absolutely NO evidence that wormholes actually exist. Theoretically they are possible, but unlike some of the ridiculous answers you've seen here they would not allow faster-than-light travel nor teleportation. Instead, a wormhole would be like a shortcut between locations in space. To get an idea of what this means, draw a couple of dots a few inches apart on a single piece of paper. Now fold the paper so that the dots are opposite each other. You'll notice that the distance between the dots has decreased significantly--a shortcut. In the movie 'Contact' Jodie Foster was transported through wormholes.

Answer 3

Actually wormholes are like two blacholes joined end to end.
they suck objects at one end and throw them out the other end(in a completly different time and space). This is possible only by the presence of anti gravity(anti-mass and anti-force). Theorotically, (by quantum mechanics) they exist. but there has been no practical observation of a worm hole.
If they exist then it could revolutionize space travel. For example if we want to go to a very far of galaxy (in the order of millions of light years) then we just have to create a warp in space-time (a worm hole) and go through it. We would reachthe other galaxy in no time at all. They are like express trains connecting two places.
With wormholes we can also do time travel.

Answer 4

In the Brans-Dicke (BD) theory, wormhole existence is determined in the Jordan representation. The Einstein representation correctly describes the geodesic motion of a test black hole that responds to the tensor mass mT of a bounded gravitational system. The central body’s active mass m as calculated in the Jordan frame determines the change in time of the area of a bundle of light rays and the motion of a test particle in Keplerian orbit. In the Jordan representation, strong-field BD wormhole solutions can exist and the energy density and the radial and lateral tensions are negative at the wormhole throat. However, the Einstein representation minimally coupled scalar field energy condition eliminates wormhole solutions within the BD weak-field approximation, C=-1/(ω+2).

Answer 5

in all probability a great wormhole can't sort clearly. Physicists will generally invoke a hypothetical substance called "unique count" as a fashion to theoretically build and look after one. This substance has detrimental mass, and subsequently detrimental gravity, which could be mandatory to maintain the two ends of the wormhole open. I study a piece of writing by skill of Stephan Hawking that asserts wormholes ensue clearly on the Planck scale, plenty smaller that atoms. They consistently sort and then disappear back swifter than our skill could be to discover them. He pronounced, inspite of the incontrovertible fact that, which you will desire to be enlarged by some skill, in all probability utilising unique count to maintain it. He believes this might by some skill be impossible, inspite of the incontrovertible fact that, simply by fact it may desire to enable time return and forth. Time return and forth includes paradoxes, which continuously shows to him that it would not be achievable.

Answer 6

i think they almost certainly do. ask yourself what a wormhole actually is. a wormhole is really just a name given to an area of folded space.
if you take a piece of paper and put two dots on it , some distance apart. in our physical universe the shortest distance between thes two points is a straight line.
now a wormhole can be represented by taking the paper and bending it untill the two points are touching. the shortest distance between two points is really no distance at all if spacetime could be folded as represented above.
as a side issue, granted that faster than light travel is a zero probability, should there be more research into gravity and perhaps, supergravity that would allow instantaneous travel anywhere in the universe?

Answer 7

Yes

Answer 8

Remember that is ONLY a theory so it has to be proven before we can actually admit they exist.

Answer 9

There is such a thing term this after a certain speed some imbalance.

Answer 10

ya i mean it cause every particle in this universe every particle has an anti-particle associated ... so it is true that there are worm holes..... the best example is scientist has predicted an anti-earth with full of anti-particles and theoritically confirmed that they do exist but not in our universe but in anti-universe
