A possible resolution to the paradoxes resulting from wormhole-enabled time travel rests on the many-worlds interpretation of quantum mechanics. In 1991 David Deutsch showed that quantum theory is fully consistent (in the sense that the so-called density matrix can be made free of discontinuities) in spacetimes with closed timelike curves.

The key to the whole idea is wormholes—specifically, a type of wormhole called a ring wormhole. Now, wormholes are already entirely theoretical, so this discussion is going to get weird. And ...
This occurs when the two wormhole mouths, call them A and B, have been moved in such a way that it becomes possible for a particle or wave moving at the speed of light to enter mouth B at some time T 2 and exit through mouth A at an earlier time T 1, then travel back towards mouth B through ordinary space, and arrive at mouth B at the same time ...
Another possible system is the wormhole, which connects two distant locations as though by a shortcut. Both distortions would need to create a very strong curvature in a highly localized region of space-time and their gravity fields would be immense.

In the FOX/Sci-Fi series Sliders, a method is found to create a wormhole that allows travel not between distant points but between different parallel universes; [119] [120] objects or people that travel through the wormhole begin and end in the same location geographically (e.g. if one leaves San Francisco, one will arrive in an alternate San ...
A Scientist Says Time Travel Is Possible With Ring Lasers. Tim Newcomb. March 2, 2023 at 5:02 PM. ... Ronald Mallett loves the concept of time travel. He has since he was a kid. At 77, the former ...
Intergalactic travel for humans is therefore possible, in theory, from the point of view of the traveler. [7] For example, a rocket that accelerated at standard acceleration due to gravity toward the Andromeda Galaxy and started to decelerate halfway through the trip would arrive in about 28 years, from the frame of reference of the observer.
