The question is very unclear, but that doesn't really matter. As soon as you say
"Can you build a time machine . . .", we have enough to render an answer, which
is "no".
How to Build a Time Machine was created in 2003.
Nobody has invented a time machine yet. But Einstein said if you travel faster than the speed of light you will travel back through time.
no
Albert Einstein certainly did not build a TIME MACHINE, nor has anyone built a TIME MACHINE. However, Einstein's theories do give us a better understanding of time, and do show some possible ways of changing the speed at which time passes for a given person (if you travel in a space ship at close to the speed of light, time will pass slower for you than it does for people left behind on Earth, and you will effectively travel into the future, while simultaneously traveling to a distant location in space).
No.
No human or machine can travel the light of speed. No matter how close you are to the speed of light if you have all the thrust in the universe you cannot get going past the speed of light. The familiar notions of absolute space and absolute time independent of your relative motion must give way.
No,time travel is possible but it is somewhat difficult,as einstein said,"if an object travels with speed of light , the time near it would become slow and time travel wold be possible. All we need to is to produce such machine /spaceships that can travel up-to light's speed.
There are 2 prevailing theories, first you have to conquer travel at light speed, or bend time/space to bring points closer together.
Basically time machine is the mathematical concept till now it is only concept. When you travel more than the speed of light then the time goes to infinity. But when you say that you can travel with the speed of light at the same time you are kicking all the laws of physics and throwing them into dustbin because all the assumptions and theories given by the scientist will go wrong.

At the speed of light, time does not exist as we understand it. According to Einstein's theory of relativity, time slows down as an object approaches the speed of light, eventually coming to a stop at the speed of light. This means that for light itself, time does not pass.
