Also I'd very much like to dispel the idea that this somehow proves that time travel is possible, something going faster than light isn't going backwards in time, it's just going faster than light.
In the same way that when a car drives past a cyclist it isn't going back in time, it's just going faster than a cyclist.

Time alteration and travel is actually possible, but not in the sense that "you can go backwards into the past" but rather in the sense that "you can fire yourself several years into the future without feeling so much time pass"

If you want to discuss traveling backwards in time, that's what antihydrogen's for. We contained that shit for more than fifteen minutes, and that's just an amazing thing to talk about in and of itself.

Time dilation is a thing, and you can blast off into the future if you're traveling at high speeds; the closer you are to 3e8 m/s, the more time passes for your second.

Technically anyone who's ever been in a plane is a time traveler in that sense, to say nothing of astronauts.
(Actually, unless I'm wrong or I'm mixing my concepts here, anyone who's ever moved anywhere would be a time traveler, granted only in an infinitesimally small fraction of time, but still)

It's one of those annoying concepts that's hard to explain but is actually really simple once you get it.

Yeah, to be fair, I don't believe we'll ever hit a point where we could send a man back in time, and therefore have legitimate sci-fi time travel. It really is a bummer to think that time is a human invention; I mean, sure, there is an initial point when an object is created, and an end point when the object ceases existence, but that's all just a load of crap if you get into the philosophical stuff.

And what you're saying about movement is correct; anything with motion will feel time dilation, although your dividing factor will be almost exactly 1 if you have a normal, easily-achieved speed. Which means your time frame of reference will equal a stationary object's frame of reference~

This is a really important concept to know for Physics 201, and it is a total bitch to comprehend, but yeah once you get it, it's a really simple concept~
