If mental time travel is unique to humans, then it must have emerged over the last 6 million years since the line leading to modern humans split from the line leading to modern chimpanzees. Perhaps the first hard evidence for the evolution of mental time travel in humans comes in the form of Acheulean bifacial handaxes associated with Homo ...
Theoretically, scientists say time travel is possible. The challenging part is recreating time travel in real life.
Time travel is a concept in philosophy and fiction, particularly science fiction. In fiction, time travel is typically achieved through the use of a device known as a time machine. The idea of a time machine was popularized by H. G. Wells's 1895 novel The Time Machine. [1] It is uncertain whether time travel to the past would be physically ...
A recent study claims to have calculated a potential method of time travel. It involves a highly theoretical object called a “ring wormhole,” which is a type of wormhole that connects two ...
The theoretical study of time travel generally follows the laws of general relativity. Quantum mechanics requires physicists to solve equations describing how probabilities behave along closed timelike curves (CTCs), which are theoretical loops in spacetime that might make it possible to travel through time.

Not all time travel stories involve a person literally moving through time. Peggy Sue doesn’t actually go back to high school in Peggy Sue Got Married; rather, she dreams it (although there is ...
Certainly, time travel is a concept that philosophers have tried to grasp and theorize about ever since its invention. [5] Dave Goldberg wrote for Nature Physics that "As to the practical possibility of time travel, Gleick is something of a sceptic. Common sense, he argues, suggests that the past really is immutable, no matter how clever the ...
As far as timing goes, travel seems to be easier at certain times of year, seemingly at times related to the changing seasons. Claire first traveled back in time just after the festival of Beltane ...
