Traveling back in time - or not?!?

On June 26, 2009 a man named Stephen Hawking, had thrown a party, it was full of almost everything you would need for an adult party. A lot of people where invited but no one showed up.  He had figured this would happen, because he had said "it was a welcome reception for time travelers!" He had been joking but it was in some way a experiment to prove that time travel into the past was impossible! But Mr.Hawking maybe wrong, well in the math world. Even at the tinniest quantum level, strange things happen. Some people think that time travel is possible because of physics, it should probably be basted on what Einstein's theory, that describes gravity of space and time which is one thing called 'space time.' But tell me if you believe in time travel or not?
