Recent experiments offer tentative support for time travel's feasibility—at least from a mathematical perspective. The study cuts to the core of our understanding of the universe, and the resolution of the possibility of time travel, far from being a topic worthy only of science fiction, would have profound implications for fundamental physics as well as for practical applications such as quantum cryptography and computing.
Closed timelike curves The source of time travel speculation lies in the fact that our best physical theories seem to contain no prohibitions on traveling backward through time. The feat should be possible based on Einstein's theory of general relativity, which describes gravity as the warping of spacetime by energy and matter. An extremely powerful gravitational field, such as that produced by a spinning black hole, could in principle profoundly warp the fabric of existence so that spacetime bends back on itself. This would create a "closed timelike curve," or CTC, a loop that could be traversed to travel back in time.
Hawking and many other physicists find CTCs abhorrent, because any macroscopic object traveling through one would inevitably create paradoxes where cause and effect break down. In a model proposed by the theorist David Deutsch in 1991, however, the paradoxes created by CTCs could be avoided at the quantum scale because of the behavior of fundamental particles, which follow only the fuzzy rules of probability rather than strict determinism. "It's intriguing that you've got general relativity predicting these paradoxes, but then you consider them in quantum mechanical terms and the paradoxes go away," says University of Queensland physicist Tim Ralph. "It makes you wonder whether this is important in terms of formulating a theory that unifies general relativity with quantum mechanics."

Don’t think there has been a generation since the fall that didn’t include evil.
I went back in time and found out that one of my grandfathers was a dentist, and the other was an ophthalmologist. Quite a pair o’ docs.
On that first Easter morning, before the risen Christ ascended to Heaven to present His blood on the Mercy Seat, He told Mary Magdalene not to touch Him....and then told her to go tell the disciples about it...John 20:17.
Wherever Heaven actually is, the discernible farthest edge of the Universe is 12+ billion light years away. If Christ had to travel anywhere close to that distance, it had to be far faster than the speed of light, because He’d been there and back and had the encounter with Mr & Mrs Cleopas on the Emmaus Road early that evening.
So He would have had to travel at something like the speed of THOUGHT. However, if Heaven is in another dimension from ours, Christ could just pass back and forth between the two dimensions.
Ver-r-r-ry inter-r-r-resting!
That legacy has been passed on to Tata Motors.... :p
Slingshot around the sun?
Your redundancy is incomplete. You dropped the second use of “already”.
I’ve actually looked into Deloreans from time to time.
I think that would be so coooool to roll up in one of those....
A place in Houston has all the parts needed to build you one I hear.
I am already researching this at the department of redundancy department where I am researching this.
And thanks to time travel, just as everywhere in the world is very similar, now everywhere in time is very similar.
Funny you say that. I call time a current in an ocean called eternity.
I think it was Jesus in the furnace in Daniel and it was Jesus who wrestled with Jacob.
I think the biblical eternity is something other than linear time unending.
No Sheldon, I wouldn't go back and kill your MeeMaw!
Say hello to Jean Claude Van Damme for me!
Bump for later reading..............yesterday..................
Or get a Tardis.
I think that’s right. But me, I’m more of an “artistic” guy who likes the look and the nostalgia of it all.
Putting me in front of a box of parts would be laughable at best.....
I think so too.
What if our linear timelines were extended out into a plane? What if all the moments in our lives were preserved without end--not as frozen moments of the past but as living realities that never pass?
The analogy threw me: the particle that flipped the switch is consistent with that same particle being sent back in time to flip the switch. Either 50-50 possibility is preserved with the identical properties. But in the grandfather-killing scenario, the person is sent back to kill his grandfather if and only if his grandfather is killed: it’s still a 50-50 shot, but now the properties are reversed and it should be impossible.
