WebSep 27, 2024 · Time travel, as a famous concept in science fiction, fascinates people for a long time. However for physicists, this is not only a beautiful dream, but also a interesting problem to discuss mathematically. In the community, there are generally two directions about time travel: (1) does it exist and (2) if it indeed exists, what can we do. In this report, … WebSep 20, 2024 · Time travel’s future might look a little brighter if the correct approach to quantum gravity turns out to be string theory, currently the most popular contender.

Time Travel - Is It Possible? Quantum Physics Time …
Until recently, most studies on time travel are based upon classical general relativity. Coming up with a quantum version of time travel requires physicists to figure out the time evolution equations for density states in the presence of closed timelike curves (CTC). Novikov had conjectured that once quantum mechanics is … See more In 1991, David Deutsch came up with a proposal for the time evolution equations, with special note as to how it resolves the grandfather paradox and nondeterminism. However, his resolution to the grandfather paradox is … See more A related description of CTC physics was given in 2001 by Michael Devin, and applied to thermodynamics. The same model with the … See more An alternative proposal was later presented by Seth Lloyd based upon post-selection and path integrals. In particular, the path integral is over single-valued fields, leading to self-consistent histories. He assumed it is ill-defined to speak of the actual density state … See more • Novikov self-consistency principle • Grandfather paradox • Ontological paradox See more WebSep 24, 2024 · Mr Tobar and Dr Costa say they have found a way to "square the numbers" and Dr Costa said the calculations could have fascinating consequences for science.
