Theoretically it is possible, but it isn't pragmatic. After all electrons have been shown to move forwards and backwards in time. And there exists regions in this universe where time moves backwards.
How would you know if an electron moved back in time?
Where did you hear this information about regions in this universe where time moves backwards?

I have no diea lol. I just heard what I heard on Discovery Channel. Anyway I read somewhere I think it was wikipedia that if something goes more or faster than the speed in light than it will actually go back in time instead of into the future, or maybe that just has to do with wormholes.What are entanglement experiments?
If SOMETHING approaches the speed of light its mass will increase and go towards infinity. So technically speaking anything with a MASS can’t even reach the speed of light. However, let’s say you try. You’re onboard a spaceship and your friend is observing it (with some rather nifty telescope from Earth). As you approach the speed of light your FRIEND will see the clocks on the ship start to tick slower. You, however, se no such slowing down…
You are, relative to the Earth and your friend, travelling into the future. Should you somehow reach the speed of light, your friend will observe you and your ship and the clock onboard seemingly STOPPING. Again, you experience no such thing.
Should you SOMEHOW manage to break the universal top-speed, your time becomes a so-called complex number.
Again - the only "things" that can travel at the Universal max-speed are massless entities like photons, and they can't slow down.
Anything with the ability to CHANGE speed has mass and must move at velocities lower than c.
While wormholes may not give us the means to travel in time, if we could construct them, they certainly would give us the means to travel through space and reach distant stars relatively fast 🙂

That just blows my mind away...

Photons, which are the quanta ("particles"😉 of electromagnetic radiation (which includes light) are said to have a rest-mass of zero, this in contrast to particles of matter (eg, a proton), which have a rest-mass >0. This is the crucial difference which allows light to move at cee (lightspeed); indeed, dictates that it must move at that speed, in accordance with the laws of physics.
ty 🙂 now i get it.

Cool theory. Stephen Baxter makes use of it very nicely in one of his "Manifold" series scifi novels (probably "Manifold: Time"😉.
