From Discover Magazine:
Efforts to understand time below the Planck scale have led to an exceedingly strange juncture in physics. The problem, in brief, is that time may not exist at the most fundamental level of physical reality. If so, then what is time? And why is it so obviously and tyrannically omnipresent in our own experience? “The meaning of time has become terribly problematic in contemporary physics,†says Simon Saunders, a philosopher of physics at the University of Oxford. “The situation is so uncomfortable that by far the best thing to do is declare oneself an agnostic.â€
I’m not sure the human mind can truly grasp a world in which time does not play a vital part. It’s staggeringly difficult to even ponder what this question truly means. I’ve always been interested in the edges of science, where if you squint hard enough in the right direction, science looks a lot like philosophy or religion.
Incredibly interesting stuff.
