Stephen Hawking

We have all heard of the Stephen Hawking. He is the reknown physician, scientist, etc. He is involved with virtually anything sciency. Recently, he began a program on the Discovery Channel that discusses several different topics that concern the universe. He explores topics from here on earth to the beginning of the universe.
Recently, he just had a short discussing the possibility of time travel. Throughout the program, he discussed how time travel is not possible. His methods of proving this theory were both noteworthy and comical. For example, he held a party and invited people from the future by placing invitations in metal canisters that would not decompose and placed them so that people in the future would be able to find them. When his party was held, however, no one from the future traveled back in time proving that time travel had, and will not, be invented in the future.
However, I recently found an article from him explaining the possibility of time travel. Take a look at it! click here. His explanation for this is complex yet simple. But go ahead and read it so I don't risk sounding like a fool that I probably already have.
