Time travel is possible
It's has been proven that it is possible, the laws of physics allow it, but I doubt we would ever develop the technology needed to do it.
Only in the movies or books...
Time is a man-made measurement of the frequency the earth rotates, revolves around the sun or the moon around the earth.
Time travel is not possible because time is not a DVR
Exactly this. Even time dilation just shows that our atomic means of measuring time isn't consistent with speed
Of course it is. We are all traveling through time in a forward motion at a fixed rate. Theoretically, one could travel forward faster than the fixed rate by traveling at or near the speed of light.
The big question is: Is traveling backward in time possible? The answer seems to be no.
That's correct. What's impossible is keeping from time traveling.
Time stands still for no one.
