This article is available exclusively on medium.com It is a unique review that combines factual physics with a review of the sci-fi fictional TV series “Dark“. Part 1, Part 2 and Part 3 of this series are available.
In the Physics of “Dark” – Part 3 the concept of closed time-like curves CTCs will be further explained by considering how physicists since Einstein have understood causality — the nature of cause and effect.
Carter-Penrose diagrams will be introduced and used to highlight how CTCs, time travel and wormholes are consistent with our current understanding of general relativity.
The work reported here contains original insights into how time travel through wormholes for can be represented in spacetime diagrams.
