time travel
I am in deep regret over one day, trivial as it sounds, I need to go back
Will time travel ever exist?

i wonder if we will ever be able to travel back to our memories...surely some crazies would want to spend money on the idea.....
IF you could create a wormhole (a sort of link between two points in space and time) you could only create it with a point in the future. Basically, if you can't travel to a time before you could travel in time. There is also the idea of travelling at relativistic speeds which would slow your view of time down relative to a person in our time frame (e.g. what might take us 10 years could take someone in a relativistic rocket 1) so you could 'travel' into the future but you couldn't come back.
Both these things are purely theoretical and extremely unlikely to ever be a possibility.
To summarise: no, you can't travel through time except at the rate of one second per second.

But someone will try to kill their grandfather to check if the paradox actually works

I believe you can travel forwards in time, in a sense.
If you took a space shuttle and travelled at close to the speed of light for 80 years, and then returned to Earth, you would be in the distant future (as in, the year 3000, not the year 2172). Wikipedia told me
but I saw where it was coming from, it's about relativity and time dilation.
Surely if we could travel in time someone would have travelled back to us? This kind of thing really messes with my head.
I am working on it , would appreciate ppl not anticipating too much , i am already under pressure. Give me 5 more years

Yes but we are the present

right?Oh yeah! See
I can't cope with this!

If you took a space shuttle, and flew out into space for just 40 years (travelling very close to the speed of light), close to 59'000 years would have passed on Earth! This is because the faster you travel, the slower time travels (relative to you). Wikipedia can be unreliable sometimes
Very interesting stuff though! Original post by DemolitionLovers

maybe when it gets invented they create laws and regulations about not going back and messing with us ancient civilizations :P
Time travel is possible. To the future that is.
Little known fact.
Busted have been to the future and apparently it's not that exciting. The people live underwater. And I think my great-great-great-grand daughter is doing fine as well

Very interesting stuff though! Didn't he say that more time would have passed on earth? He's not wrong.
If you accelerate away from the earth and return, you are younger than your twin.

Also Wikipedia probably won't be around then to correct.

Very interesting stuff though! So it wasn't incorrect? How close you were to the speed of light would have a huge impact on the time in years, so both 3000 and 59000 could be possible

Yes - I also believe this to be true.
Time travel is actually an impossibility. For time travel to be possible, we would need to find a way to travel at or faster than the speed of light. The goal we would be trying to achieve would to catch up to or 'take over' the beam of light in essence. However, this is impossible. Just for an example, however absurd it sounds, just imagine this: you put a torch on the ground. You switch the torch on, such that a beam of light fires out of the torch. Now, just imagine that we figured out a way to run at the speed of light. So, you would imagine than we are running along side the beam of light yes? Well actually, we wouldn't be. We would be moving close to 300'000'000 m/s (speed of light) relative to the Earth, but, the thing is with light is that it is a constant. Even though we would be running at the speed of light, light would be moving at 300'000'000 m/s relative to us. So it is still moving away from us at 300'000'00 m/s. So we could never catch up to it!

Hopefully somebody from the future will give a comprehensive breakdown on what and what not to do when time travel comes about.

Doesn't matter, it's a theory. You won't need that much energy to get to 80%, surely it would be possible with high output fission engines or something?
