what is a wormhole?

Answer 1

It is a hole made by a worm, also known as wood borers, mainly in trees.

Answer 2

In physics, a wormhole is a hypothetical topological feature of spacetime that is essentially a 'shortcut' through space and time. A wormhole has at least two mouths which are connected to a single throat. If the wormhole is traversable, matter can 'travel' from one mouth to the other by passing through the throat. While there is no observational evidence for wormholes, spacetimes containing wormholes are known to be valid solutions in general relativity.

The term wormhole was coined by the American theoretical physicist John Wheeler in 1957. However, according to Coleman and Korte, p.199 of 'Hermann Weyl's Raum - Zeit - Materie and a General Introduction to His Scientific Work', Hermann Weyl invented the idea of wormholes in 1921 in connection with his analysis of mass in terms of electromagnetic field energy.

This analysis forces one to consider situations..where there is a net flux of lines of force through what topologists would call a handle of the multiply-connected space and what physicists might perhaps be excused for more vividly terming a ‘wormhole’.

– John Wheeler in Annals of Physics

The name "wormhole" comes from an analogy used to explain the phenomenon. If a worm is travelling over the skin of an apple, then the worm could take a shortcut to the opposite side of the apple's skin by burrowing through its center, rather than travelling the entire distance around, just as a wormhole traveler could take a shortcut to the opposite side of the universe through a hole in higher-dimensional space.

I've read somewhere that in particle accelerator experiments physicists have created wormholes but on a sub-protonic level. The energy used was tremendous. So making a wormhole big enough for a man to pass through would take an astronomical amount of energy and dark matter--if it exists--ther is a lot of evidence that it does.

If you're thinking space craft propulsion google m2p2. This space craft drive system is not to far away from protype. It could theorically reach Proxima Centari in 25 yrs!!!!

Answer 3

Hypothetically if space can be folded like a piece of paper so that two points which are far apart on the surface of the paper were to touch, and a hole were to be bored through the paper at that point, then one could go from one point to the other without traveling the intervening distance on the surface. It is believed by Astrophysicists that blackholes bend space and time around them. theoretically if two blackholes in distant parts of space were to bend space enough that they touched, a shortcut would be created from one point to the other. This Short cut has been called a wormhole. Keep in mind this is all theoretical and hypothetical, and even if it could happen you would have to deal with the black holes somehow. But that is the basic theory. Unless you meant the holes left by worms when they eat their way through things.

Answer 4

Wormholes connect one location of a universe to another location of the same universe. A wormhole should be able to connect distant locations in the universe by creating a shortcut through spacetime, allowing travel between them that is faster than it would take light to make the journey through normal space

Answer 5

a wormhole is a cosmic construction that allows a traveler to go between point A and point B in space, with the use of a fourth dimension. its like taking space, and folding it in half so that two ends are touching (kinda hard to imagine a cube folded in half innit :P) the traveler then walks through where the two points are touching, effectively traveling from point A to point B, faster than light (though not locally)

Answer 6

The concept of the wormhole is pure conjecture. The idea is that matter that disappears down a black hole may re-emerge from a "white hole," that is an antigravity source. There is no evidence for white holes, but if they did exist hen the matter that vanishes down a black hole would still be conserved. The worm hole is the connection between a black hole in one part of the universe and a white hole in another part.

Answer 7

A wormhole is a hypothetical feature of space and time which is essentially a 'shortcut' through space and time.

Answer 8

It is an odd manifestation of super curved space, picture the severe bends in a great river, they may come so close that only a few inches separate the river from itself, a canoeist instead of paddling for many hours may simply step from the canoe and walk another step to get to the river, it is quite a short cut.

Answer 9

Effectively it's a whole through space itself, connecting 2 distant points together.
