What is a warm hole.?

Question

Black holes are well known to those who are interested in cosmology or physics but what are warm holes, can some body explain them in simple way.

Answer 1

A "warm" hole? Wow, you've sure left yourself open for some zingers :)

You probably mean "wOrm" hole. First off, no such thing as a worm hole has ever been discovered or detected. Theoretically such a thing would be a kind of a short cut between two places in the universe. For example, if location 'A' was physically 500 light years away from point 'B,' traveling through a worm hole could cut the distance in half. You can demonstrate the idea for yourself by putting two dots some distance apart on a piece of paper. Fold the paper so that the two dots are opposite each other and you'll see that the distance between them has decreased considerably. Some theorists have reported finding worm holes in solutions to certain of Einstein's field equations.

If you saw the movie "Contact," Jodie Foster traveled through worm holes during her space trip.

Answer 2

Worm holes arn't complicated.

Essentially, space is bendable. The 'fabric' of our relatively flat universe is bendable through the use of energy. Energy in space time bends space time, which is essentially what causes gravity.

The idea of a worm hole is to bend space in such a matter that something far is now something close, or essentially, you've bent space such that it has bended towards you. It is also theorized that wormholes exist at many points in space but opening them would require vast energy.

As an example, the fastest way to cross a piece of paper isn't to travel straight across, but is to fold the other end directly to your destination.


In theory I'm pretty sure spinning a lot of matter and antimatter could create a sufficient wormhole to travel to say, andromeda. But you'd need a mass of antimatter, like, the size of our sun.

Simply put, our technology cannot produce enough energy to generate a wormhole.

Answer 3

Anything that can be cut can also be sewn. It is mathematically possible to take two black hole geometries, and sew them together along their "tears". This gives rise to wormhole solutions to Einstein's equations, in which two otherwise separate "universes" are connected by a throat, or tunnel, Such wormholes could also connect different regions of the same universe, . In principle this would enable us to take shortcuts to distant parts of the Universe. The problem is that within Einstein's theory such wormholes are very unstable. The throats tend to collapse in a much shorter time than it would take to get through to the other side, so that traversing such wormholes is in practice impossible.

BUT

We have no evidence for the existence of such worm holes, and, as described above, you'd be torn apart and fried long before your remains disappeared into a black hole, so even if worm holes do exist, they do not appear to be very useful means of transportation.

Answer 4

You already have a lot of good answers. But one of the major characteristics of the worm hole as a shortcut hypothesis has not yet been mentioned. That is, to make that shortcut from point A to point B in our observable universe, you would need to leave our 4 dimensional, space time continuum to take that shortcut.

Using the two dots on a piece of paper model...when you fold the paper, you are folding our observable 4D universe. When you jump from point A across the gap between the folded sheet to point B, you will leave our universe to take that shortcut. That is, you have to go into some dimensional realm higher than four dimensions to travel a worm hole from place to place in our observable universe.

There are a lot of things that make such shortcut travel unlikely. Insufficient controllable energy is one of them...as some of your answerers have pointed out. Unimaginable rending forces trying to rip you apart in the shortcut worm hole is another possibilitiy. Although, it is not clear that the laws of physics found in our observable universe would apply to higher dimensional space-time.

Answer 5

A hypothetical space superhighway that connects 2 regions in space, that allows a person to travel a distance that would be impossible to travel, even at the speed of light. Theoreticaly worm holes can be created by black hole. Quasers may be the exits for wormholes.

Answer 6

A worm hole is not the same as a black hole. It is the idea that there is a shortcut through space and time. Good explanation and diagrams at this link -

Answer 7

a worm hole is simple described as a teleporter from one spot and time to another. most people think there just a fantasy because one has never been spoted.

Answer 8

A warm hole is that one where you put your finger into and the temperature is about 98.3 Fahrenheit degrees

Answer 9

Worm holes U div!

Answer 10

It's a "worm hole", not a warm hole.

Google it. I'm not wasting my time explaining it to you if you can't even spell it.
