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.
If traversable wormholes exist, they might allow time travel. [31] A proposed time-travel machine using a traversable wormhole might hypothetically work in the following way: One end of the wormhole is accelerated to some significant fraction of the speed of light, perhaps with some advanced propulsion system, and then brought back to the point ...
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 ...
The Final Countdown (1980): A science-fiction time-travel movie in which the aircraft carrier USS Nimitz passes through a wormhole back to the eve of the Japanese attack on Pearl Harbor. The anomaly returns and sends it back into the present, before it has a chance to affect the outcome.
Ronald Mallett is still working on rotating lasers to travel back in time. ... Ronald Mallett loves the concept of time travel. He has since he was a kid. At 77, the former University of ...
For example, an Earth–Moon wormhole whose far end is 0.5 seconds in the "past" will not violate causality, since information sent to the far end via the wormhole and back through normal space will still arrive back on Earth (-0.5 + 1) = 0.5 seconds after it was transmitted; but an additional wormhole in the other direction will allow information to arrive back on Earth 1 second before it was ...
Smeenk uses the term "predestination paradox" to refer specifically to situations in which a time traveler goes back in time to try to prevent some event in the past. [7] The "predestination paradox" is a concept in time travel and temporal mechanics, often explored in science fiction.
“A photograph is like a wormhole, providing a direct link between two distantly separated locations in space and time – the present in which we view the photograph and the epoch in our lives ...
