Einstein's theories suggest that we can "travel" forward in time by moving close to the speed of light. You know the example with the twins and one gets on a spaceship and one stays on earth. The space ship travels around near the speed of light for a few minutes and when he/she returns many decades have gone by on earth. The spaceship kid is a few minutes older and the earth kid is an old man. But is it theoretically possible to move backwards through time?

yes if for example you live in england and go to Australia then go back to england then you in a sense have travelled back in time

Here is what I would do;
Build a space ship at the equator. Fly straight up and position yourself directly over the base you took off from. You should have a telescope on the ship where you can see the base below you. Matching your speed in orbit around the earth with the same speed the earth is rotating at the equator.
Now fly in the OPPOSITE direction of the earth's rotation, twice as fast as the earth's rotation. Since you will be going BACK a day in time, you should be able to stop, and look down at YOUR SHIP on the ground, still waiting to take off.
I once talked to a cousin of mine who worked for NASA as an engineer and told him this idea. He said nothing in reply. And I then asked him, is this why the shuttle always goes up in the same direction as the rotation of the earth? He got up, walked away, and never talked to me again.
Hmmmmm.

There is nothing in any of Einstein's theories that say it is impossible to travel backwards in time .
So theoretically it is possible although very difficult .I believe one possible way would be to use wormholes a kind of short cut through space and time .
But i think we r a long long way from that kind of technology

remember and ability isn't destroyed interior a black hollow.So trillions of trillions of years from now because the temperature of the universe falls less than the ambient temperature contained in the black hollow, it is going to initiate to radiate. So, i visit't vouch for the theory you describe, yet there doesn't seem tp be something except time that would ward off them from reuniting, or looping as you describe.

i think if 100 einstiens work on it for a whole century non stop (and those 100 einstiens had the ability to live a 1000 years)then ya i think it is possible

you can't travel back in time as far as i know. you can only move forward. but oh how i wish i could. there are so many things i wish i could alter in my past.

I "travel back in time" via looking at pictures from my past.

Sure! Haven't you ever heard of the flex capacitor?

I haven't seen anybody do it yet,I would only say in our minds!
