Sorry mate, but I think I'm going to have to call shenanigans on this one. First off, if you use general relativity (gravity) to slow time, then you would have to experience a much greater pull. I don't have the numbers atm, but I have the feeling that anything great enough to make a difference would crush you. On your second point, the light is not sitting still, it is instead curved inward until it hits the center of mass (assuming it crosses the event horizon). You could of course argue that being that close would slow down time (and the light ray) as a result of general relativity, but you're space ship would be outside, running at a different time, where it was still traveling slower then the speed of light in their reference frame.Mr Snuffles said:

Some astronauts have time traveled actually, to the future. It isn't like they went a few years or hours, but a few thousandths of a second. So yes, it is possible.
the only point i was getting at with the link was that they can teleport particles for now, and soon will be able to do objects, a.k.a. "matter" if you will. human beings have a ridiculous amount of sub cell structure so being able to move a human being and having to do it at near speed of light is ridiculous thoughts for now. and i seriously doubt we have an infinite future, i was just saying if we do happen to live for a few hundred thousand years, it might just happen.Staskala said:
while i get what your saying, and think that is highly logical and probable, all this is somewhat theoretical and we dont know what the hell truly happens in black holes and whatnot...so at this point a bar of soap has much a clue as we do about what the hell goes on in there.Continuity said:
This is FACT, time travel is possible, the OP was thinking of traveling Wells style, so the transition happens whilst the machine stays in one position, that was the mistakeAiden_the-Joker1 said:
We do not have a strong enough grasp of physics to make a definitive statement one way or another.
Don't get me wrong, I'm overwhelmingly surprised by everything we appear to know, but there is a massive amount of Hubris in saying we know anything to be impossible.
Putting aside pretentious wordplay that is.
It will make your weekend absolutely amazing.
"My girlfriend dumped me." "Aw dude I'm sorry." "Oh no big. I watched Hawking's Into the Universe, I'm good as gold."
At any rate, I imagine traveling back in time results in you being in a parallel existence, but that's only because I personally can't fathom how you wouldn't break some equation otherwise. BUT I'm about as far away from a deeply educated physicist as you can get without losing the basic understanding.
By basic I mean...verrrrrrrrrrry basic.
Science is a beautiful thing that should never be seen as done, I'm sure time travel and many paradoxes that we have now will be conquered and look silly to people in the future.
Just think of the whole geocentric universe thing, the motion of the other planets and how it seemed to all suggest that there was no other answer. These days we look at it, well most people look at it and say "Derp! How could you think we are in the center!"
Kinda bad example, but you get my point

While I'd be willing to argue (fruitlessly) that paradoxes are just a matter of us not understanding time and space well enough, I will say that the Stephen Hawking's video series was absolutely amazing and ever last one of you should watch it.Isalan said:

.Damn. Mind == Blown. I vote to perfectly bring it to 50/50 :O!
1: Yes. I remember reading a horror story about your first point. Man creates time machine, disappears. Girl tries time machine, sends herself back in time 3 days. She is at the point in space where the earth was when she sent herself back. She floated for two seconds then exploded from the lack of air pressure. Fun. Maybe it would be possible, but it would require a shitload of of planning when the time machine would be in the exact same position. (Which isn't possible, since every year the Earth tilts a little bit more on its axis) Something like that would have to move in time and space.PrimoThePro said:
We would have to either (To move forward/slow down time) Be able to stay within the Event Horizon of a Black Hole without being sucked in and circumnavigate said Horizon, or use Worm Holes (Potential Theory) Though it would take a huge amount of energy to widen them.
Yes, multiple dimensions exist. Ever hear of Shrodinger's (Yes, it's misspelled. Bite me.) Cat? Stuffed in a box with a vial of poison. If an electron hits the vial, vial breaks, cat dies. In one universe, the cat dies b/c the electron hit. However, in another universe, that was created from this single choice, a cat lives. There must be a damn near infinite amount of universes by now.
EDIT: Almost forgot: Moving into a parallel timeline does not count as time travel, in my opinion. You are merely moving into a different place that just happens to be at that time. That would be more like moving sideways in time, to me.
Time is an abstract concept created by carbon-based life forms to monitor their ongoing decay.
The fact that clocks measure differently on things like satelites is a mass/energy... thing.
Then again, I've heard that if you put bacon bits on a strip of bacon you will create a bacon to bacon time paradox.

I always think its time travel cause all my clocks in my room are set 15 mins ahead (gives my morning mind the illusion i got more sleep then i did).
but on topic, sure its possible. Many people thought many things were impossible, yet they exist.

There's no such thing as time. It's a tool, much like a ruler. Sure, you can change how long an inch is, but that doesn't make everything shorter or longer. You're just changing a fake tool you use to keep track of things around you, the tool is never those things themselves. Time is the same thing, a tool used to track the movement and progression of everything.
do we really want time travel? i dont wanna live the rest of my life running away from skynet =[
i would have to go with black hole for time travel though

I'm a time traveller! I travel through time at the astonishing rate of 1 second per second!! (Cookie for the reference)
Joking aside, from what I can gather, moving forward in time at an increased rate (by approaching the speed of light etc.) is technically possible, but I highly doubt the possibility of moving back in time.
So do I vote the odds are stacked against it?
Very interesting thought btw, of completely changing location by time traveling at all, never considered that.

It's possible but very unlikily we will invent a machine where time travel is possible. Although saying that I believe you would make two machines for safe time travel. Send and receive. The receive is turned on at the point of time you want to return to. It grabs all the information like location(time&space etc) then when ever you want to return tot hat point in time you turn on and enter the sent machine.
Note though if to people tried the use the machine they will return to the same spot even if they used the send machine hours or whatever apart. They would then be crushed into each other. The receive machine will need a reset function where it grabs a whole bunch on locations a few mintues apart. Which it mosy likily will take a lot of energy to just get the first one. So you will want to know how many people you will be sending and when.
Would be funny if the receive machine grabed two locations 5 mintues apart and the two people entered 30 seconds apart. The first guy will need to wait a few mintues for the other person.

There are theories that go as far back to Einstein's time of how time travel would be possible. In fact, physicists are already working on how such formulas could be accomplished.
Then again, I'm using an avatar from a game that seems to use time travel as a core for an entire story, so what can you do?
