what are some different ways to travel in time?part or future?examples?

Answer 1

Traveling through worm holes and black holes are the only 2 methods I know of, that scientists have explored.

Answer 2

Time Travel is funny. You can do it, but you can't change things. When you come back, everything pops back to the way it was supposed to be like shaking wrinkles out a carpet.

You have traveled in time, but you just don't/can't remember it.

When you go into the future, you can see what it will be like, and tell everyone what it was like from your time, but when you come back, it all reverts to how it was.

Answer 3

Get a really fast spaceship that can travel at near light speed. Go to the Andromedae galaxy and return. You will have aged a few years but on Earth, hundreds or even thousands of years will have passed! That's because of Einstein's relativity. We're constantly traveling at the speed of light through the space-time continuum. If you're stationary in the spatial dimensions (like sitting in your chair), then you're traveling through time at the speed of light. If you're moving very quickly through space, you move slower through time. You can never exceed the speed of light because to do so would mean you'd have no mass. So one way to travel to the future would be to stay in space for a few years while moving fast.

To travel to the past you would need a wormhole. A wormhole is a theoretical bridge between 2 regions of space. It works through 2 black holes, which bend space so much around them that they create a singularity. Now say you wanted to go to the Andromedae galaxy. You could go through a wormhole both ways and arrive back home before you left. Wormholes haven't been found yet however. And even if they are real, there is a chance that going throuh one would close it off forever, so you couldn't return home.

Another way to go back in time would be to break the speed of light. But like I said earlier, you couldn't do that unless you had zero mass. Otherwise, it would require an infinite amount of energy. Our most powerful particle accelerators can speed up electrons (with very small mass) to 99.999999996% the speed of light, but can never reach it. Photons can only reach light speed because they are massless particles.

There are ways to observe time travel though. One way is Cherenkov radiation. A charged particle passes through an insulator faster than the speed of light, mostly with water as the medium. You can see this happen in nuclear reactors. That's why they have a blue glow. Another way to see back in time is by looking in the mirror. By the time the light wave reflects into your eyes, a very small fraction of a second has passed. You can see billions of years into the past by looking through Hubble space telescope. It takes that long for the light from distant galaxies to reach us.

With any method of time travel, you can never go back before the time machine was created. (see sources)

There are other theories for time travel but they're more complicated. See my sources.

i like to sleep and dream I'm still in the 70s.
