Time travel could be possible, but only if parallel timelines can coexist

Time travel could be possible, but only if parallel timelines can coexist

Imagine a world where time travel isn't just a concept of science fiction, but a reality. The key? Parallel timelines coexisting. Let's delve into the intriguing possibility of time travel, exploring the role of parallel universes and their potential to make it feasible.

Is time travel real?

Our modern understanding of time and causality comes from general relativity

Introducing multiple histories

Recent work by Barak Shoshany, Jacob Hauser and Jared Wogan shows that there are time travel paradoxes that Novikov’s conjecture cannot resolve.

Arguments against time travel

Building a time machine seems to require exotic matter, which is matter with negative energy.

Eliminating the paradoxes

In physics, a paradox is a purely theoretical concept that points towards an inconsistency in the theory itself.
