If you could get in a space ship and fly to Alpha Centauri at almost the speed of light, you'd get there in what would seem to you like a few days, and when you looked back at Earth over 4 years would have elapsed for it. It's effectively a forward-only time travel.
Also, time is relative, and is different in different spaces. Galaxies traveling faster through space are experiencing time more slowly than we are.

What? It would feel like 4.3 years for you if you travelled there wouldn't it?

I don't doubt the complexity one bit.

But imagine it is all fiction. And Steven Spielberg wrote it...... waitttttt a minute......

No, if it seemed like 4 years to you and the people on Earth, than there would be no time dilation.

When traveling near the speed of light you are traveling a light year in Earth time, and a year of Earth time will go by much faster for the person going near the speed of light (about a day). So the problem of traveling that fast is only that everyone else would age so quickly that wasn't onboard that you wouldn't want to make the journey, unless you didn't care about losing touch with 4 years of time.

I'm not sure if you're being serious or not. The Internet doesn't confer sarcasm well sometimes. But it's definitely not fiction, and not all that complex, every physics student understands this stuff, it's been around since the early 1900s.

You're still travelling that distance though, surely it would just mean that more than 4 years would have elapsed for Earth? Hm. I see where these ideas collide. You're probably correct.

The hypothesis is,
If you move faster or almost as fast as the speed of light away from earth into space, time is going faster for earth and slower for you.

I don't know how they can possibly know this though....

Well take what you know so far:
1.) Someone on Earth would watch the ship take about 4 years to get there, because it's about 4 light years.
2.) You know time elapses at about 1 day for someone traveling near the speed of light for a year on Earth.

Given those two things, 4 years for the Earth observer is about 4 days for the traveller. So how could it not seem like 4 days for them?

There have been many experiments. One example is particle half lifes, they're predictable, but when the particle is traveling very fast the half life is extended. Another example are GPS satellites which are traveling much faster than the surface of the Earth and so they have to adjust their timing to account for the time dilation. Atomic clocks are so accurate they have to be adjusted based on their altitude above sea level. All these adjustments in time are based on math, the same math predicts all of these effects. There are numerous tests in the Wikipedia link I've already provided your. I implore you, read it.

Do u think it will ever be possible to travel that fast?
