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.

Grünbaum critically examines the nature of space and questions related to its absolute or relative nature. He explores different theories of space and assesses their implications for our understanding of the physical world. Philosophy of Time: Grünbaum addresses the nature of time and its relationship to space. The book discusses the ...
However, the Novikov self-consistency principle is intended to go beyond just the statement that history must be consistent, making the additional nontrivial assumption that the universe obeys the same local laws of physics in situations involving time travel that it does in regions of space-time that lack closed timelike curves.
The usual space x, y, z and time t coordinates themselves are real and spacetime is not complex, but tangent spaces are allowed to be. [ 6 ] For several decades after Einstein published his general theory of relativity in 1915, he tried to unify gravity with electromagnetism to create a unified field theory explaining both interactions.
Philosophy of space and time is the branch of philosophy concerned with the issues surrounding the ontology and epistemology of space and time. While such ideas have been central to philosophy from its inception, the philosophy of space and time was both an inspiration for and a central aspect of early analytic philosophy. The subject focuses ...
In physics, spacetime, also called the space-time continuum, is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects, such as how different observers perceive where and when events ...
Science fiction author H. Beam Piper, in his Paratime series of short stories and novel that multiple timelines exist as "worlds of alternate probability on the lateral dimension of time." [17] In Dragon Ball Z, hyperbolic time chambers - in which one year inside is equal to one day outside - are used to accelerate martial arts training.
Absolute, true and mathematical time, of itself, and from its own nature flows equably without regard to anything external, and by another name is called duration: relative, apparent and common time, is some sensible and external (whether accurate or unequable) measure of duration by the means of motion, which is commonly used instead of true ...
