Time can be slower or faster based on many factors, whether it be size of the interpreter or the minds ability to calculate/compute the sensory input it receives. But perceiving time as faster or slower than another persons perception is in no way time travel. Nor can you "rewind" or "travel back in time", particles can only exist in two places at one given time, thus teleportation is possible, but even via teleportation you are not time traveling

Time Travel is impossible, Time is merely your own perception of the energy around you, aka your own interpretation..... Einstein was wrong about e=mc2 and yes, you can travel faster than light, there is no limitation to anything except your physical body. To think that one man, who's life was in the mere beginning of cutting edge technology and knowledge, was capable of understanding all of the factors involved in physics, is to be naive. He barely even scratched the surface of what is and what can be, and thus jumped to conclusions based on experimentation and calculation limited to the perspective built by human based civilization.

Is there a machine that teleports you to a different time? Of course not. Will there ever be? No.
However, time isn't just a perception for us. Time is exactly the speed at which light travels in your location. Speed travels faster in a vacuum than it does on Earth. Gravitational pull also affects the speed of light. If the speed of light can be slowed surrounding you, then the speed of everything around you slows.
If, one day, we can create a device that slows down time for us while the rest of the world stays at full speed, then you will travel through time. For example, if we have a pod in space that slows down time by 75%, then in 100 years, you'll have only aged 25 years, while the rest of world has aged 100.
Time also goes slower the higher you are. If you're on a ladder, then time, by small fractions, is slower.
And the idea about the train that Einstein said is hilariously wrong. He fails to account for the fact that time is merely an interpretation that the mind calculates based on sensory input

The warp engine is based on a design first proposed in1994 by Michael Alcubierre. The Alcubierre drive, as it's known, involves expanding the fabric of space behind a ship into a bubble and shrinking space-time in front of the ship. The ship would rest in between the expanding and shrinking space-time, essentially surfing down the side of the bubble.
The tricky part is that the ship wouldn't actually move; space itself would move underneath the stationary spacecraft. A beam of light next to the ship would still zoom away, same as it always does, but a beam of light far from the ship would be left behind.
