A bootstrap paradox, also known as an information loop, an information paradox, [6] an ontological paradox, [7] or a "predestination paradox" is a paradox of time travel that occurs when any event, such as an action, information, an object, or a person, ultimately causes itself, as a consequence of either retrocausality or time travel. [8] [9 ...
Michael Devin (2001) proposed a model that incorporates closed timelike curves (CTCs) into thermodynamics, [23] suggesting it as a potential way to address the grandfather paradox. [24] [25] This model introduces a "noise" factor to account for imperfections in time travel, proposing a framework that could help mitigate paradoxes.
Time travel is a concept in philosophy and fiction, particularly science fiction. In fiction, time travel is typically achieved through the use of a device known as a time machine. The idea of a time machine was popularized by H. G. Wells's 1895 novel The Time Machine. [1] It is uncertain whether time travel to the past would be physically ...
Time travel is deterministic and locally free, a paper says—resolving an age-old paradox. This follows research observing that the present is not changed by a time-traveling qubit. It’s still ...
Ronald Mallett loves the concept of time travel. He has since he was a kid. At 77, the former University of Connecticut physics professor still isn’t backing down from his theory: A spinning ...
Physicists have long known that some solutions to the theory of general relativity contain closed timelike curves—for example the Gödel metric.Novikov discussed the possibility of closed timelike curves (CTCs) in books he wrote in 1975 and 1983, [1] offering the opinion that only self-consistent trips back in time would be permitted.

Inspection paradox: (Bus waiting time paradox) For a given random distribution of bus arrivals, the average rider at a bus stop observes more delays than the average operator of the buses. Lindley's paradox : Tiny errors in the null hypothesis are magnified when large data sets are analyzed, leading to false but highly statistically significant ...
The twin on the ship sees low frequency (red) images for 3 years. During that time, he would see the Earth twin in the image grow older by 3/3 = 1 year. He then sees high frequency (blue) images during the back trip of 3 years. During that time, he would see the Earth twin in the image grow older by 3 × 3 = 9 years.
