very interesting, i had no idea it worked with "time", i gotta find out more about how that really works, very interesting indeed :O

Its not the height of the clock, but the speed of the clock that alters its time due to special relativity (moving closer to speed of light=time slow down)

so all i need to do is put myself in a very strong gravitational field and i can time travel

I'm sorry, you can thumb my comment down to the depths of hell, but there are several things in this video that are not true...

#4 well if you make a statement like that you should at least tell us what your arguments are!

#2 the video correctly states you have to account for both corrections. Read up on general relativity.

we actually need to detect nuclear before detonation.... that would be nice..

I knew how gps works but what does detection of nuclear expolosions have to do with anything ???

I bet they can detect when someone farts, and who it is.

but awesome btw.

How can GSP satellite detect nuclear explosion (or whatever visible event) when it is basically a trasmitter (not receiver)?
