In sure universes, reaching a time loop is feasible with out breaking physics andrey_l/Shutterstock
A causal loop is a basic time journey conundrum. In the event you ship data to the previous – say, you give Albert Einstein the method E=mc ² earlier than he theorises it himself, then he publishes it and also you go on to seek out it in a textbook – you’ll create a state of affairs through which the data has no true origin.
A brand new evaluation exhibits that one of these causal loop is feasible in additional theoretical universes than had beforehand been anticipated.
