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 ...

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

One of the most famous paradoxes ever, the grandfather paradox, cautions against making changes that could break the timeline if you were to ever travel back in time. But, according to one scientist, ...

Vanderbilt University physicist Lorenzo Gavassino isn't so sure this is as big an obstacle as time-traveler pessimists have ...

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 ...

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 ...
