Say 300-500 years from now, if we dont extinct ourselves by then, could we have the knowledge to time travel? Look at how far we've advanced in technology in the last 50 years and the rate that it is increasing...
If so, then do we have people walking around from the future right now? They'd probably be smart enough to know not to change anything...
What about aliens? Could they be our future smarter selves? Maybe our earth becomes inhabitable so the elite humans get to inhabit this new planet with new laws of gravity so their body has less mass, which is why aliens are described as skinny. The reason we cant find them is because in our time, they dont exist, but maybe in 500 years we've colonized the moon or something and learn new laws of physics which dont exist on earth which is why we dont have that technology yet.
Am I crazy?

I don't have any science upon which to base this opinion, but here goes anyway.
I think that causality, e.g. cause and effect, is a basic, fundamental, and immutable property of the universe. Therefore, I think time travel will prove to be impossible.

If you took off from Dallas at 2PM on 10/19/2006 and traveled around the earth in the opposite direction of the earth's rotation at twice the speed of light for 1 hr and then landed back in Dallas, it would be 3PM 10/19/2006 when you landed. If you traveled in the direction of the earth's rotation, it would still be 3PM 10/19/2006. You will have crossed the international date line several times.
If you travel towards a star 40 light years away at twice the speed of light for 1 year, you will see the where the light particles are that will strike the earth in two years. It will be 1 year later.
Time is something that only exists because we keep track of it. It is not another place or dimension.

Maybe. Men once believed that the world is flat and everything revolved around the earth. So probably in 300-500 years, time travel might be possible. Although I personally believe that time travel is a dangerous thing. It might even cause the world's destruction.
And you are not crazy, you just have a good imagination. Great things and inventions were products of imagination. So it is OK to think and imagine :-)

When you see a star that is a 100 light years away you see the light that it gave off 100 years ago. If you could travel faster than the speed of light leaving Earth toward that star and come back to Earth to say what you saw before Earth can see it happen. You will have traveled into the future because you will see what's happening before Earth does.

No, I don't think so.
You know, if there was time travel, I will imagine that the crucifixion of Jesus will be a crowded future touristic time travel spot. Or Kennedy's assassination.
From the descriptions and the footage on these two incidents there were not millions of people present as one will expect from the existence of time travel.

No,there will be no time travel other than forwards,the way we do it now.It's not a matter of technology.That will never be able to control time.If you think about it,our bodies function in a certain amount of time.Mess with that and they would no longer function properly.Going through time at a faster rate either way would totally screw us up.Aliens,if they exist,are from some where else,not some when else.

Yes you're crazy but i must say its a very thought provoking question nonetheless! Sadly though, I don't think time travel will ever be possible: once something has happened, i don't think there's a way to revisit it: likewise, there is no future predetermined: its a nic ething to believe, that we can go back and forth in time: but i just dont buy into it. as for living on another planet or something? maybe one day.. but not anywhere near our lifetimes!

Time travel, in the sense that you see in movies and stuff, is impossible. Thanks to Einstein for proving that.
Although, if you know about Special Relativity, it states that as you reach speeds close to speed of light, time slows down for you. You'll age slower.
And contrary to what some people are saying, Einsteins equations do not say you can travel backwards in time. Traveling in time is impossible. Time only slows down for you if you travel closer and closer to light speed.
However, I believe that if somehow we were able to surpass the speed of light, then a person traveling faster than light will NOT go back in time and take a trip through history, rather the person will get younger. And to that person and that person ONLY, he/she will reach a destination before he/she embarked on the journey.
This is only my view based on my studies in Special Relativity.

I have a theory that the elapsion of time will decrease infantecimally, similar to an asymptote, but will never become negative or reverse. So no, I dont think this technology is possible. Perhaps we can make time stand still?

Not likely, humanity will probably be doomed before the technology developed.
But, there maybe other unpredictable elements that produce time travel though.
