Researchers have discovered that it’s possible to speed up, slow down, or reverse the flow of time in a quantum system. This isn’t exactly time travel, but is instead implementing or reverting to ...

New research suggests paradox-free time travel is mathematically possible. The universe might self-correct, letting you alter ...

Time travel has long been a subject of fascination in science fiction, but recent scientific endeavors suggest that it might ...

A scientist has mathematically proven the physical feasibility of paradox-free time travel. But once you go back, you might not like what you find.

Scientists are trying to figure out if time travel is even theoretically possible. If it is, it looks like it would take a whole lot more knowledge and resources than humans have now to do it.

Scientists say they have achieved 'temporal cloaking' – manipulating light in a way that makes it appear as if 50 trillionths of a second never happened. Now, they'll try to expand the gap.

A scientist has mathematically proven the physical feasibility of paradox-free time travel. But once you go back, you might not like what you find.

Now, scientists from the Austrian Academy of Sciences (ÖAW) and University of Vienna are adding a kind of time travel to the list.
