Einstein-Rosen bridge

 

 Einstein Rosen bridge is a consequence of Einstein's theory of relativity.It states the possibility of small wormholes in the space, or "spacetime" more accurately.The bridge or tunnel so created will act as a tunnel that can allow us to travel in space and time to another corner of universe. Basically the bridge or tunnel formed bends space and time. Think of a paper with points on its extremities, now fold the paper as the two points as conciding, so in place of going from one  point to another, you can directly go through the paper at the point where the two points concide, hence cutting down the travel distance by a very large amount. Now just think of the paper as the universe and the two points as two galaxies trillions millions of light years away, instead of covering all the time that would take billions of years, we can straightaway go there through the wormhole. Actually the wormholes or "Einstein-Rosen Bridges" are very very small and are present of very small amount of a second. We cannot presently use these wormholes for our advantage, but the one thing that can stabilize these small wormholes is negative matter or exotic matter, which is theoretically possible.
