Besides, all you'd need is a wormhole, which shouldn't be that hard given that the timeframes involved are of the same scale as the distances. What will human technology look like in a million years, given what we've accomplished in the last 200? A million years is blink of an eye on a cosmic scale. An alien civilization might have a several billion year head start on us.
I can understand moving ahead in time but I'm not so sure one can move backwards in time.
The urge to hug a departed loved one again or prevent atrocities are among the compelling reasons that keep the notion of time travel alive in the minds of many.
While the idea makes for great fiction, some scientists now say traveling to the past is impossible...
There are a handful of scenarios that theorists have suggested for how one might travel to the past, said Brian Greene, author of the bestseller, “The Elegant Universe” and a physicist at Columbia University.“And almost all of them, if you look at them closely, brush up right at the edge of physics as we understand it. Most of us think that almost all of them can be ruled out.”
I don't think that's it. All the human experimentation (alien abduction) doesn't jive with the future human theory. If they are from our future then they already know about us as it is archived to be sure. All they need do is consult their "files". Or if they really want to see how 20th or 21st century human operate they could clone us from some DNA that I'm sure was reserved in some manner.
My best guess is that it's an alien peoples who have learned to "bend" space or as Star Trek fans know "warp" it. That's how they can move faster than the speed of light.
