I recently watched the one about time travel. In it he said that if a big train that circles the Earth 7 times a second or to put it in scientific terms near the speed of light everyone on the train would begin travelling forward in time! This is because time would slow down on the train so say for every 1 minute that passes on the train more than 1 minute will have passed on Earth. Just don't ask me how please as I don't think I'm a super smart person, (hence "abitclueless", which is really abitbewildered/abitconfused", I'm probably not though I'm probably only thinking that way due to low confidence and low self-esteem). Anyqay the programme also theorized that the Universe has a cosmic speed limit in that nothing can go faster than the speed of light - including the people on the train.
Interesting! If only I could go back though, back through my own timestram with relevant memories and fix all the mistakes I've made in my life or relive the good times that are in my past. I'm hopefull that I'll still have good times to look forward to in the future though.
Actually less time passes on a moving object than one that stays at rest. This is the so-called twin paradox. If one twin remains on earth and the other goes to Alpha Centuri at nearly the speed of light and then returns at high speed he barely ages at all, while the twin who stayed home ages 8 years.
