Which hypothetical subatomic particles are theorized to always travel faster than the speed of light and thus, if they existed, could potentially be used for sending information or matter back in time?
What is the 'Bootstrap Paradox' (also known as the causal loop paradox) in time travel, where an object or piece of information has no original creation point but exists solely through time travel?
Which theoretical space-time construct, often depicted as a tunnel connecting two distant points in space-time, is sometimes proposed as a hypothetical mechanism for faster-than-light travel or even time travel?
Which scientist and logician, a close friend of Albert Einstein, developed a theoretical model of the universe (the 'Gödel universe') in which time travel to the past is theoretically possible through closed timelike curves?
In the 'Terminator' film series, how do characters primarily travel through time?
The science fiction film '12 Monkeys' (1995), starring Bruce Willis, is a remake of which influential 1962 French short film?
In the film 'Interstellar,' due to extreme time dilation near the supermassive black hole Gargantua, one hour on Miller's Planet is equivalent to how many Earth years?
The concept of using 'cosmic strings' – hypothetical 1-dimensional topological defects in space-time – as a potential mechanism for time travel was explored by which acclaimed physicist?
In the original 'Star Trek' series, the USS Enterprise frequently achieved time travel by performing what maneuver around a star or planet?
What kind of time travel paradox occurs when a time traveler goes back to change an event, but their actions are actually what cause the event to happen in the first place, thus making the past unchangeable?
