How or where would you find enough power to make time travel possible?

there are other ways to travel thru time other than technological… society will just have to do an experiment and find out the results first-hand.

zero point energy

With Tesla coils of course!

See the Montauk Project (the book)
Also see Project Rainbow
And the Philadelphia Experiment

It may be eventually possible to send matter through time or space, with a large enough energy input. Since your memories are electrochemically stored in your brain, such “transport” would likely leave you without memories or personality. Not a thing most people would wish to do. Use of a black hole or wormhole is theoretically possible, but not practical with any technology we have or can envision today.

Sorry to burst your bubble, but time travel is impossible. You can alter the rate of progression of time, but you cannot redirect the arrow of time for either a small part or the whole of the universe.

If you were to send the whole universe back in time though, you would need an external energy source and an external measure of what time is – both of which are unknown to mainstream science in practice or theory.

That is what the Vulcans said too and we all know how that turned out.

But seriously, what makes you so sure that it is impossible? On what grounds do you make that call? Especially considering that general relativity does allow time travel in certain scenarios.

oh I just love threads like these… anyone mind if I watch?

The hypnotize I heard would use Worm Holes. I cannot explain this well. Science Channel had shows on this . What is clear is you would have to travel through time at light speed or something close . Some say, the energy needed would burn you alive.
The ramifications of Time Travel are dangerous to our society. Do we want to fight Wars over ? Do we want to risk changing history? The outcome could be worse for many.

@philosopher Worm holes in theory takes you ti another part of this universe or another dimension. Mankind has yet to produce enough power to send even the Milky Way galaxy back in time, much less our nearest celestrial neighbor. So how would we have the power to take galaxies 500 trilion light years away back i time with us seeing each galaxy is like an organ in the body, one interconnected part of a greater whole? Half of the power in our grid is supposingly lost out there somewhere. Until that is solved I do not believe anyone will be fighting the same war over again, giving Hitler the A-bomb, warning Kennedy he better use a Pope Mobile in Dallas, or any other tinkering one might wish to have done.

Time travel is possible and happening right now. OMG. We are moving through time one second at a time. Is that not traveling through time?

@Hypocrisy_Central – What have you been smoking? I want some.

@ragingloli Think of the Grandfather Paradox, but with energy. However you conceive of performing your trip through time, you will need a monstrous amount of energy either to warp space-time or to travel faster than light. Once you have travelled into the past, you will be able to go to your future position and that energy will still be there.

I think in certain circumstances time travel may be possible, but the path of time (for want of a better term) that allowed the travel would collapse into itself and that strand of the multiverse would cease to exist. That is the only way I can reconcile it.

@Futomara Time travel is possible and happening right now. I have mused maybe we are not traveling through time but stationary and everything is just progressing through stages or rates of decay, and we measure it by tics on a clock.
