Scientists zero in on why time flows in one direction
"Regardless of the direction they run in, the new universes created in these big bangs will continue the process of increasing entropy. In this never-ending cycle, the universe never achieves equilibrium. If it did achieve equilibrium, nothing would ever happen. There would be no arrow of time."
Maybe there is no "arrow of time"; maybe it just seems like there is because our brains have evolved to function in a time-symmetric universe. Could the concept of "cause and effect" really be nothing more than a helpful mass delusion?
