Note: (this will only let you go further in time slover than others)
Step 1: Go into space (with an atomic clock for proof)just near enough to a black hole to be highly effected by its gravity without getting sucked in(be careful lol)
Step 2: Stay there for a sufficant amount of time.
Step 3: Go back to Earth where there is another atomic clock.
Clocks measure time, relative to gravity. However, no matter where I go, in 50 Earth years, I'll still be 50 Earth years older. If you can find a away to escape that, you have invented time travel.
I thought the idea of time travel is to stay at point A, and go backwards or forwards in time.
We are talking about points in time here, as if there is a timeline, not points in space.
The idea of time travel is that you get from point A to point B without having to go through any space in between.
I don't think that is the case necessarily, if you could travel and end up in a different time that one would otherwise expect then I would call that time travel. For example, just purely making up numbers to get the point accross, if I were to travel around the world over and over at 90% the speed of light for what I record with my watch to be 10s and I land and find that the world has aged 3 months since I started flying, wouldn't you call that a form of time travel?
and going forwards isn't either (due to the yet-non-existence of 'future', time travel is impossible.
The proposition is that you can make everything else age faster than you do. If it were possible to instantly jump 10 years into the future, it isn't much different to making everything else age 10 years more than you do is it not?
Wether you define time travel as a way to travel through the timeline at a different rate than other objects or as an instantaneous way to get from one point in the timeline to another, I can't really argue with you on your definition, but I believe the instantaneous part is unnecessarily limiting.
Really? How so? Last I checked, clocks measure time relative to time. We can use atomic clocks which aren't affected directly by gravity, we have long moved from the era of pendulums.
However, no matter where I go, in 50 Earth years, I'll still be 50 Earth years older.
You are taking a constant external frame, years of the earth, as you're measurement so that isn't a useful statement at all. If you were to take a clock with you and go to a place with different gravitational potential to that of earth, you will find that the clock will be out of sync and gradually become more and more out of sync with one on the earth, even if the two clocks are identical. Are you saying that when 50 earth years has passed, you will look at your clock and if it hasn't been roughly 438000 hours you will conclude that your clock is faulty?

What I'm saying is, just because you get a clock to say something different, doesn't mean you've altered time. I can go to Mars with a clock, fifty years earth time can pass, and regardless of what the clock says, I'll still be 50 earth years older, even though I'm on Mars.
What I'm saying is, you can't use location to alter time.
Many of these black hole and light speed theories are hypothetically true in ideal conditions, but they will probably never happen. So time travel might be possible, but it is very unlikely it will ever be successful.

Do you know what the theory of relativity is? Look up special relativity. The OP is about general relativity, while special relativity focuses on how the faster you go, the slower time passes. General refers to how the denser an object, the slower time passes.
Example: If you wanted to kill Hitler, it would have alredy happened. The first time you live thorugh a day... thats makes whatever happened that day impossible to change because it would have already happened. Try that for logic
Well, it IS possible, despite the example. If, indeed, time travel was possible, then the real purpose would be to prevent the entire space- time continum from collapsing. For example, if I time travel to last week and change the batteries in a flashlight, then last week, I noticed that the batteries in a flashlight had been changed. I then found a note telling my past self when to time travel. If I don't actually travel back when I have to 1 week later, a past event won't have a cause and the continum will collapse, or the batteries won't be changed.

Since Waffle doesn't seem to understand the point of this, I'll try to explain it with other words.
If you went back in time and changed something that had happened to you in the past, then it would already be changed the first time you lived through it, as it only happens once, even if you experience it twice.
This is a bit tricky though. If it did happen the first time, you wouldn't need to change it in the future, and you would never have went back. This means that you would not have changed it, and it did not happen the first time. Long story short, everybody dies and you made the monkey cry.
