Our journey has taken us from the beginning of time to the very edge of the universe. The legacy left to us by Albert Einstein describes a reality far more wonderful and mysterious than anything we could have dreamt up.
The idea of wormholes dates almost as far back as general relativity itself. Friends do you know that Karl Schwarzschild was the first person to realize that Einstein's equations of general relativity predicted the existence of blackholes. More specifically, his blackhole contained a singularity at its center. Singularity is a point of infinite density where time itself came to an end. At the singularity, all the known laws of physics break down. This troubled Einstein.
In 1935, Einstein published a paper with his collaborator Nathen Rosen in which they attempted to prove that Schwarzschild singularities did not exist. By using a mathematical trick known as a co-ordinate transformation, they were able to rewrite Schwarzschilds mathematical solutions so that it did not contain a point where space and time stopped. They showed that the singularity became a bridge connecting our universe with a parallel universe. These Einstein-Rosen bridges are what we know as the wormholes.
