Share In the simulation, the researchers examined two possible outcomes for a time-travelling photon. In the simulation, the researchers examined the behaviour of a photon traveling through time and interacting with its older self. In their experiment they made use of the closely related, fictitious, case where the photon travels through normal space-time and interacts with another photon that is stuck in a time-travelling loop through a wormhole, known as a closed timelike curve CTC.
About us Is Time Travel Possible? But could he really skip between different periods of history at will? Travelling forwards in time is surprisingly easy. If one were to leave Earth in a spacecraft travelling at an appreciable fraction of lightspeed, turn around and come back, only a few years might have passed on board but many years could have gone by on Earth.
It allows for the possibility of wormholes — a kind of tunnel through spacetime connecting otherwise very distant parts of the universe.
More restrictively still, theoretical work by Kip Thorne of Caltech using a partial unification of general relativity with quantum physics suggested that any wormhole that allows time travel would collapse as soon as it formed.
Thorne did, however, resolve an apparent issue that could arise due to by time travel within the confines of general relativity.
Thorne found that for point masses traversing a wormhole, no initial conditions create this type of paradox. That would probably be beyond even the Doctor himself. The folowing links are external You might also like:"The approach of two such strings parallel to each other, will bend space-time so vigorously and in such a particular configuration that [it] might make time travel possible – in theory.
Is Time Travel Possible? Time travel has always fascinated humans. The idea of being able to change the past or the future creates infinite possibilities. The most common form of time travel is through the use of a time machine, although in some cases, characters with mystical powers can transport others in time.
Unable to prove this impossibility, Hawking changed his mind, making headlines when he said, “Time travel may be possible, but it is not practical.” 2- The universe may not allow change when. Is Time Travel Possible?

Should government pay more attention to Terrorism? ” The approach of two such strings parallel to each other, said Gott, will bend space-time so vigorously and in such a particular configuration that might make time travel possible, in theory.
“This is a project that a super civilization might attempt,” Gott told LiveScience.
