Wormholes

For those who don't know about wormholes ---- Wormholes are tunnels in space-time which can help in travelling to distant places with a shorter route i.e inside from the wormhole and can also help you to travel back and forth in time

There are two possibilities for development of a wormhole :
(a) When there is a black hole and leads to a white hole in another place
(b) When a body of massive mass bends the fourth dimension (space-time) ,  the bend that is made    creates a  tunnel in space time (wormhole).

For those who don't know about white holes ,they are like black holes but have a reverse function than of a black hole.Like a black hole sucks matter , a white hole vomits or throws out matter.
