In this video, I discuss what psychology has to say about time perception, how time does not pass, and how the phenomenon of time is entirely a creation of our brain. Time is discussed with the analogy of a movie in which the illusion of motion, or the illusion of change, is in the mind, due to the brain stitching together different still frames of reality to create what we experience as time.
The flow of time is relative and depends on many conditions. Time does not flow but is experienced as passing at different rates depending on those conditions. The passage of time and how fast time passes depends on age, the species of animals, and even how fast your heart beats for example. In addition, the brain changes how you perceive time so your experience makes sense to you, even when it must distort what actually happens in reality in order to do so.
I offer a theory of time as given by philosophers that is consistent with the belief of many scientists interested in time. Time does not exist the way we experience it; time does not flow; time is an illusion.
