Twisting Space-Time into Loops It’s hard to say who ever thought about time travel, but the physical concept of time travel typically traces back to Albert Einstein’s theory of general relativity.

New simulations are set to enable "time travel" to solve problems in the real ... it is theoretically possible to leap through time. "Imagine wanting to send someone a gift: you need to send ...

The grandfather paradox is just one of the thorny logical problems that arise with the concept of time travel. But one physicist says he has resolved them.

What is time? Is time travel possible? For centuries, these questions have intrigued mystics, philosophers, and scientists. Much of ancient Greek philosophy was concerned with understanding the ...

we've known that time travel—at least moving forward through time—is possible. Einstein didn't pull this theory, or even the notion that time travel is possible, out of thin air. Rather ...

But actively studying them could unlock the mysteries of our early universe and may even be key to a form of time travel, some physicists suggest. Traveling back in time through relics of the ...

There were time travel movies before Back to the Future came out in 1985 – an adaptation of HG Wells’ The Time Machine won an ...

But if time travel became possible for humans it could create deep paradoxes, like meeting your younger or older self. According to Einstein’s theory of relativity, the faster anything travels ...

In a breakthrough study, researchers have managed to reverse time using a quantum computer. The scientists from the US and Russia have demonstrated time reversal by sending a qubit (the basic unit ...

Does the universe have an edge? Is time travel possible? What is a black hole, and in what sense are space, time and gravity a matter of "geometry"? The modern theory of spacetime introduced by ...
