“In Einstein’s equation, time is a river. It speeds up, meanders, and slows down.
The new wrinkle is that it can have whirlpools and fork into two rivers.
So, if the river of time can be bent into a pretzel, create whirlpools and fork into two rivers,
then time travel cannot be ruled out.”
~ Michio Kaku
Oh, I like that concept. Perhaps that is how my one character could keep traveling in a time loop. Tweeted.
