Could aliens be time-travelling humans from the future?

Another recent article with a time travel method; this time without using exotic materials.

What's more is you don't return to the exact same place you left either.
___I remember an old Ray Bradbury story wherein they go back in a time machine to hunt dino's. Even though they go ahead to find targets about to die anyway, some guy steps off the path & squishes a butterfly. When they return, things have different speelings etc.
___Since we can't prove aliens, we can't prove where they originate. So it's possible. Never mind the Klingon jokes!

The Parallel World MOdel... Isnt that the one similar to that described in a Sci-FI book by MIcheal Crichton... Timeline... That theory is quite interesting, although when you think about it, where are all of these parallel worlds stored?

It makes sense if you believe in intlligent homosapien-like extraterrestrial life. No offense, but that sounds like something from a 10 cent sci-fi book published in 1970.

No because time travel is impossible.

If intelligent life have been here for eternity, as you state in another thread, why is anything impossible. Eternity gives one plenty of time to work out any problem.

i think time travelling is impossible.
the mass of universe is constant, if u travel in time the energy of universe will be changed which won't be possible.
though a myth, time travelling stories and movies are very fascinating.

Regardless of what's been posted here:

Coming back to the topic in this thread, the answer is a resounding NO.

Make your peace with it.

- About time travel: we dont know everything about our universe, about sciens, physics, etc, so how can we claim thats impossible to travel in time (i mean, go back to the past). We can argue many paradoxs, like: i get into the past in my time machine, kill my parents before i´ve born and then what would happen? If i kill them i will not born so if i didnt born i couldnt get into the past and kill my parents. So, i am alive! Thats a typical argue but what if our universe its so strange that there are possibilities that we even not dream about? By now, it seems impossible to time travel but lets not forget that in the past it was impossible to fly or went into the moon! No one would ever imagine that!

- About life in universe and ufos. Many people say that ufos sightings are lies because its impossible to make a trip so long, even from the nearest star to our Sun. That a stupid argue. We cannot deny a thing just because it seems impossible to exist. Instead of that we should study it carefully. If aliens exist they may have ways to travel in space that we dont even dream about. So, stop saying that there are no ufos just because its a long way from their home to ours. YOu can use other argues to attack the ufos sightings, but not that one.

- There is a portuguese (i am from Portugal btw) ufologist that points 4 possible origins to aliens/ufos:
1) From this universe, like another planet in this universe or even from our own planet (like: coming from the seas; a natural phenomenon in atmosphere; USA gov secret projects, etc)
2) From another dimension, different from this one.
3) From another timeline: maybe humans from the future, like you say.
4) Spiritual origin. Maybe they could be somewhat related to spirits and other forms of existence behind our comprehension.

i think a good reason for travelling back was explained in STV and to a lesser extent demolition man, the need to verify what actually occurs in the past.

assuming that all matter in the universe isn't shrinking with complexity

then another good reason to come back would be to harvest new genetic material, earth women are easy but we're also alseep during the night, making harvesting painless and 100% efficient.

Answer is no. Sounds coool though right? I'm not sure, but Aliens made themselves known to mankind in the year 2010 as I recall from the history viewers. But no one studies history that old in my time that much. at least I think. I was always sleeping in class.
