Astrophysicist Ron Mallett believes he’s found a way to travel back in time — theoretically.
The tenured University of Connecticut physics professor recently told CNN that he’s written a scientific equation that could serve as the foundation for an actual time machine. He’s even built a prototype device to illustrate a key component of his theory — though Mallett’s peers remain unconvinced that his time machine will ever come to fruition.
To understand Mallett’s machine, you need to know the basics of Albert Einstein’s theory of special relativity, which states that time accelerates or decelerates depending on the speed at which an object is moving.
But while most physicists accept that skipping forward in time in that way is probably possible, time traveling to the past is a whole other issue — and one Mallett thinks he could solve using lasers.

No. You forego that outcome by traveling there in the first place.
If you enter a.new.space-time, from this one, you prove that things can be exchanged between the two, including tracking, weapons,.or vehicles.
Also, there is no solid consensus on time machine construction, nor practical application.
With the way we believe our world.functions, a time machine is also a gravity machine, as well as an engine.
Be surprised that more industries aren't working on it.

There are several solutions to Einsteinian equations that allow for closed time-like curves. These have been known about for decades.
Although most of these are tiny, they could be nested or chained.
If you were to find a natural circumstantial loop, or chain of them, that has always existed (say a fast spinning micro singularity/singularities), then the one might travel to any time in the past, especially if you are only sending something ultra low mass, like information.
Mallett seems to be assuming that his machine must be man made and therefore one could only send information back to the point where it was switched on.
I don't think time travel is impossible and it may even turn out to be trivial.
