Time Travel

[Artificial]

Traveling is far too dangerous for humans. An going into those will kill you. Stretch you into a singular state, instant death.

I don't think this aspect of time travel should be discussed. The energy needed to create a wormhole required for time travel is unfeasable. Better to think of it as a thought experiment, to theoretically determine if it's possible and the outcomes that would occur should it be accomplished.

You could also in theory exceed the speed of light. Problem with all of these is control, no clue where you end up or how to get back.

Did I miss something in physics? Exceeding the speed of light, can you explain the reasoning behind your statement a little bit? I have heard some physicists argue that when near a black hole, relative to an observer far away from the hole you could appear to be traveling FTL, and relative to them you may go back in time, but I think 99.9% of physicists will agree that traveling faster than the speed of light is impossible.

Traveling to the future wouldn't work as well as you seem to think. For the simple fact its lack of existence prevents you from going there. Also you're assume speed of light travel will cause time travel, which there isn't any reason to.

That isn't what occurs when you travel to the future. In fact, traveling to the future is the only form of time travel right now that we know is possible. Google the twin paradox. If we were to jump in to a space ship traveling 99.99% the speed of light, and traveled for one year before coming back to earth, 150 years may have passed on earth (not the exact amount - would have to do the math). We would have therefore traveled 149 years in the future, entirely possible.

The idea that changing the past actually prevents the changing of the past.

If you go back in time and alter anything that leads to the point in which you actually would go back in time then in fact you never will go back in time. meaning nothing ever changed.

That's just a variation of the grandfather paradox.

Time travel to a future time is possible.

The only issue would be the fact that there would be no reality until the past reached you.

No reality until past reached you? o.o Read above post.

Look up the theories of going faster than the speed of light.

Faster than speed of light is theoretically meant to take you back in time, not forward.

It not feasible to consider making one now, but we could go run into one if we found such a cosmic event.

The key point is that "relative" time travel isn't time travel. Black hole is basically spacetime being pulled in by some massive thing with an insane gravitational force that is basically bending reality around itself. Things there stop or slow down compared to things outside. Relative part is they slow down, we keep going, so time travel isn't so much they went forward as slowed down.That's the argument. Some people call that time travel,and others don't. To me its more of a you've gone out and slowed yourself down and every thing else kept going. Plus you can't really travel at the speed of light, it reaches its speed due to its dual nature as wave and particle.

In theory the event of time traveling would require the use of a fuel with an infinitely negative amount of power, in a sense, Dark Matter, the matter that all of space and many of the anomolies of space are created of and built around. And as Dark Matter is the only atomic thing in all of existance (as far as we know) with an infinitely negative amount of energy to use, it would allow for it take place, or to be that cosmic event that you mentioned.

SLowing down would be traveling to a time in the past, which in theory would allow for the world around yo to continue moving and allow you to return to a previous point in time, but since you would be stopping or even reversing the atomic flow of whatever you would be traveling. Speeding up the atomic flow, in sense of what you are saying would do the polar opposite and allow you to travel foward in time. If actuality could follow the theory.
