Brain Time

Brain Time.

What is time? Time is nothing but a construct of the human brain. The 2nd law of thermodynamics (entropy) states that a closed system will become more disordered over time. Stephen Hawking famously related "psychological time," the way we remember things, to "entropic time. "In other words, were the flow of entropy to reverse itself then literally (as far as our brains are concerned) time would be flowing in the opposite direction.

“The days of thinking of time as a river—evenly flowing, always advancing—are over. Time perception, just like vision, is a construction of the brain and is shockingly easy to manipulate experimentally. We all know about optical illusions, in which things appear different from how they really are; less well known is the world of temporal illusions. When you begin to look for temporal illusions, they appear everywhere. In the movie theater, you perceive a series of static images as a smoothly flowing scene. Or perhaps you've noticed when glancing at a clock that the second hand sometimes appears to take longer than normal to move to its next position—as though the clock were momentarily frozen…these illusions and distortions are consequences of the way your brain builds a representation of time. When we examine the problem closely, we find that "time" is not the unitary phenomenon we may have supposed it to be” David Eagleman.
