no long explanations please. i was wondering if it will be a reality in the future

Take a sheet of paper, bend it in half. Take a pencil and poke a hole through to the other side. You just made a wormhole. You can now get all the way to the other side of the paper in a fraction of the distance than if the paoer wasn't folded. Space is like the paper, it gets folded by mass. the greater the mass the more it folds. Go through it and get to another part of the universe in no time. This is not a reality for the future, it's happening now all over the universe.

Einstein's General Theory of relativity describes gravity as a curvature of spacetime. Its a bit hard to get your head around this.
As you approach a gravitating mass (say a big star) the length of a metre and the duration of a second changes compared to when you were further away. This can be seen from observations, so we know its true. You, of course, always get a metre for the length of the stick etc.
Now this means if you tried to draw an ordinary map of your journey you would get into terrible trouble, because on a normal map units do not change. So the map would show your metre stick changing in size as you moved, but you would insist (correctly) that for you it hadn't.
The solution is to allow the units - the square grid if you like - on the map to change, and this grid will then have curves in it around stars and the like.
Einsteins equations describe how you do this, and solving these equations tells you how much spacetime is bent by a given mass.
Now it is possible to find solutions to these equations that describe spacetime so curved it actually bends back on itself. Image a flat space on a sheet of paper. This is like bending the paper so much that it touches.
Where it touches there are of course two ways to get between two points on the surface of the paper. One is the normal way, across the surface of the paper. The other is through the join. This join is called a wormhole.
The problem with wormholes is that just because they exist as solutions of the equations does not mean that they can exist - even theoretically - in the real universe. In fact, it is believed from other work that wormholes could not form in our universe.

1. The wormhole theory has NOT (yet) been proved to be a method of traveling between 2 points
Because:
a. we don't know if matter is destroyed or transported to another place in a wormhole
b. there would be difficulties in testing this theory, because any matter that enters a regular wormhole cannot leave it (ie. we cannot send a probe or a spaceship to test it, it would never return and it would not be able to send back any information
In conclusion: We do not even have a unified theory about what a wormhole is, so there is no certain answer.
Hope this helps!

The wormhole is actually a shortcut between two separate points in 3 dimensions by way of a 4th dimension.
It is beleived one can be created by the merger of two black holes...but surviving a trip through it wouldn't be too likely. There's an other idea that wormholes exist in a sub-atomic realm and that only sub-atomic particles can go through them...that they're like 4 dimensional bubbles in the spacetime field.
This is easiest to explain using a geometric analogy...a flat surface (2 dimensional) with two separate points that can be made closer to each other by curving the surface (like a sheet of paper) into a 3rd dimension--creating a shortcut between the points (as someone stated earler). Like the way it's a shorter distance to China via a line going THROUGH the earth than it is going "by surface".
Sorry if this was too long...but that's about as close to "English" as I can make it. : )

The vacuum of space is actually filled with fields and because of their existence also virtual particles. This means that the vacuum has a nonzero energy density even though vacuum is usually taken to be the zero point for energy density. Now consider if we might polarize the vacuum so that some of the energy from one spot is moved to another spot. Now we have one spot that has a positive energy density relative to the zero point and another spot with a negative energy density relative to the zero point. This second spot is called a hole. Now the positive

Analogy; if you draw a line across a peice of paper you have the beginnig and end of the line. Imagine this is space and your line is a ship. You can also take the paper and fold it in two so the begining line point and end line point match together. If you poke a needle through the paper form one side(line point) to the other you are instantly from one point to another. the needle you use is a like a worm hole. Its a theroy we talk about bending space(the paper) to get from one point to another through a hole or tube(worm hole)

it is a shortcut through time and space. there is no current proof they exist. just like time travel might be possible but currently still takes several days to get to the end of the week when it is monday

a kind of tunnel through space and time. it might or might not b true as black holes(the places where these might be found) have never been explored.
