Time dilation with airplanes has to do with height, not speed.

It does have to do with gravitational potential, but the fact that airplanes do move at faster speeds than we do on Earth also causes time dilation.

The amount caused by the speed of the plane compared to the height is insignificant. Clocks in planes was what was used to confirm gravitational time dilation.

Thats simply because the planes aren't going that fast, I'm just saying that gravitational pull isn't the only factor there and that velocity does contribute to time dilation.

If one was able to fly faster than the earth's rotational speed, in the same direction, eventually one would go to the future?

And to go back in time, one would fly in the opposite direction?


not possible at all

you mean time in relation to the position of everything relative to everything else? O_o

no. that makes as much sense as the origional post...

Well, according to Einstein and his theory of relativity. The past, present, and future are all happening at once.


yes this.

There's no way to go back in time, going forward and backwards aren't equal transformations -- because when people talk about going forward in time, they're not REALLY saying lets skip ahead a few years with a button click, they're just talking about slowing down your own frame of time with incredibly high speeds. Even if there was some way to speed up your own frame of time, you would still not be going backwards in time.

And fyi, the earth's rotation has absolutely nothing to do with time travel. At all.


unless your superman, obviously...

Bovine once again is right...

save for saying their is no way to go back in time... I cant quite recall what I saw this on, but it was one of those Discovery channel specials. It was talking about focusing enough strong light on ONE focal point... (use via lasers probably) to create, practically a Gravity well, dense enough to warp timespace, but small enough to not affect us.

Based on the idea that the larger, or even more mass something has, the more energy it would require. so technically we've "sent" small sub-atomic particals "to the past"

granted, all we really did was fling them into this "Time machine" and watched them disappear. (Granted, I was tired, and buzzed when watching this program, so My memory of it isn't perfect. I will try to find a video or somesuch)

Isn't time a human concept which isn't literally real?

asking about going back in time is like asking how to make a 'nothingness' gun that shoots nothingness and how to make reload clips filled with nothingness so you can keep shooting nothingness.

Uhm..no, time is not a human concept. Time is VERY real, and the rate at which time moves can actually vary.
