ive seen quite a few vids and i suggest that all of you take a look into his and other scientists studies, such as quantum physics, theory relativity, etc.....
alot of vids put it in simple terms that an average person can understand
http://www.youtube.com/watch?v=V7vpw4AH8QQ is one which describes light, and how nothing can move faster than it and it always appears to us that its moving at the same speed, even if we are going 3/4 the speed of light, it would still seem to us it moves at same speed...meaning time travel is possible, its easier to watch, its only like 4 minutes
plus stuff like string theory and quantum physics is really interesting
oh also http://www.youtube.com/watch?v=6Q4_nl0ICao (also about 4-5 min)
^^ the scientists that discovered this are discredited because mainly of some nutcase (JZ Knight) but its still interesting
