Cosmic Strings

In this video Stephen Hawkins and Richard Gott explain how the effects of two comic stings could create a time machine. Cosmic strings are strings that are extremely dense pieces of energy left over from the big bang. The idea is that any piece of energy has the ability to bend space time. So in theory if you find two cosmic stings you can bend space to to the shape of a V. Say you have a sheet of paper, the paper is flat that represents regular space time, but say you folded it then the path from point a to point be has become much smaller that is the idea behind the warping of space time. So you can then travel what would be the shortest part of triangles legs. Therefore you would arrive faster than someone who travels of the flat space time, meaning you are in the future. The only down fall to this theory is the fact that after all this takes place a black hole would be created, causing you to fall into and endless hole.

I thought the clip was very interesting the theory of time travel through cosmic stings was a great idea. The way the clip presented the material was quite challenging to comprehend. The pictures where great along with the diagrams those really help to make up for the use of hard vocabulary and space terms. I had to watch it several times to completely comprehend the information. But overall the entire clip was very interesting.
