University of Queensland student Germain Tobar, in conjunction with physics professor Fabio Costa published a paper in journal Classical and Quantum Gravity a paper with the title Reversible dynamics with closed time-like curves and freedom of choice.
I know this is a mouthful, but is appears to prove that time travel without paradox’s is reasonable.
See if you follow this:
“The math itself is complex, but it boils down to something fairly simple. Time travel discussion focuses on closed time-like curves (CTCs), something Albert Einstein first posited. And Tobar and Costa say that as long as just two pieces of an entire scenario within a CTC are still in “causal order” when you leave, the rest is subject to local free will.”
Perhaps a more concrete example:
“In the coronavirus patient zero example, you might try and stop patient zero from becoming infected, but in doing so you would catch the virus and become patient zero, or someone else would. No matter what you did, the salient events would just recalibrate around you. Try as you might to create a paradox, the events will always adjust themselves, to avoid any inconsistency.”
I’m very encouraged, since science seems to be tracking science fiction. I want to go back in time to time and buy bitcoin in 2009.
