According to Einstein (and he was famous for coming up with theories like this that no one could disprove) is if you travelled from earth to some other planet at the speed of light, even if it took 10 years, you would be no older.

This has confused the 'illogical set' no-end for years, but if you looked at it logically, it is bullshit. Time can be measured from the time you are born. If you all of a sudden jump on a spacecraft, travel to another planet that took 2 years, you are still older in relationship to when you were born.
special relativity says that the passage of time is dependent on your speed. And this has been tested, they flew a plane the opposite direction of the earth rotation and when it landed its atomic clock was slightly different from the clock on land.

*part* of this is at the speed of light time would stand still for this person, but it's *RELATIVE* of course time would have passed for those on earth because they're travelling at a different speed.
