Roberto Emparan presented in Chile his theory of the wormholes as a shortcut in space. "Imagine you are a worm, living on an apple, and you want to go to the other side of this apple. The first way, the longest, would be to border the apple, but other way would be to tunnel through the centre and cross it. This would be the hole".
In this way, the theoric physicist, Roberto Emparan, tries to explain which has been occupied during the last time and that could mean the possibility of travelling to the past: wormholes.
