one of the craziest time theories having to do with it's relativity(which is discussed in these videos), is that if a single person were able to somehow safely sit on the edge of a massive black hole for a year, they would have only experienced/aged a years worth of time, but time eslewhere, like say on earth....could have gone through hundreds, if not thousands of years. the faster your moving, the slower time passes to the individual. crazy stuff. you will have only aged a year, while everything else has gone through hundreds...
also, i had no idea untill just a little while ago... but apparently people have kinda figured out how to break what we thought was the absolute speed barrier. people have apparently used 'quantum tunneling' to send waves at up to 4.7 times the speed of light...
"One central tenet of special relativity theory is that light speed is the greatest speed at which energy, information, signals etc. can be transmitted. In many physics-related internet newsgroups, claims have appeared that recent tunneling experiments show this assumption to be wrong, and that information can indeed be transmitted by speeds faster than that of light - the most prominent example of "information" being a Mozart symphony, having been transmitted with 4.7 times the speed of light."

"Michio Kaku makes the most complicated stuff so entertaining."
this guy is one of my heros, right alongside Albert Einstein who Michio Kaku worships. the fact that he can take such complicated science, and break it down for the average joe to really understand and appreciate is the reason he is one of the most respected theoretical physicists on the planet. the guy was pretty much born a genius. he was making atom smashers in his garage when he was only 16! "hey mom, can i smash atomic particles in our garage? pretty pretty please!"
His awakening came on hearing the news of Einstein's death when he was eight years old. "I saw this picture of his unfinished work lying on his desk," he says, "and it became like a real-life murder mystery that I wanted to solve." By the time he was 16, Kaku had bought 400lb of steel and 22 miles of copper wire and had built his very own atom smasher in the family garage. It was powerful enough to pull fillings out of teeth, but the only thing it smashed was the house. "It broke every fuse and ruined every circuit breaker," he admits ruefully.
