1.50 - 2.15 in the first video is where I go to school. The person is no professor, and time travel is impossible. You can control how fast 'your time' passes compared to the rest of the world, making it theoretically possible to travel into the future if you managed to travel near the speed of light. It is impossible to travel back in time.

Depends how you define "time travel". To go back to 1960, that would be impossible. But in the (not to distant) future, it will be possible for particles to go back to an earlier time (in the future), maybe eventually humans. I know a physicist, who is studying time travel. The gravitational field created by a laser beam in a tight circular path can distort space as well as time, and can theoretically send particals and information into the past, up to the point that the machine was turned on. He found out that it is theoretically possible.

interesting, seems crazy though. the human body is made up of 43294812748311789741 particles lol.

according to a lot of scientists its the other way around as far as travelling into the past/future is concerned - however the 'grandpa paradox?' poses an interesting question- If you were to travel back in time, and kill your mothers father (your grandfather) you could not have possible been born to have traveled there in the first place - makes me smirk
