Does Time Really Flow? New Clues Come From a Century-Old Approach to Math
Relativity makes no distinction between past, present and future; they are all fixed. In relativity, “now” does not exist.
In real life, though, we know that time flows from past to future and we live in the now. Quantum mechanics agrees with real life.
How to resolve the contradiction?
Gisin thinks he has, using an obscure, turn-of-the-20th Century branch of mathematics.
Gisin’s theory, if borne out, would explain the nature of time, reconcile classical and quantum mechanics, explain whether numbers are real, describe the nature of “now,” and might require physicists to invent a whole new kind of mathematics. Kind of a big deal!
