“Since the brain estimates the passage of time by how much information is stored within a given interval, richer memories make it feel like more time has passed. What’s neat is that this explanation sheds light on other ways that time can feel bendy to us, on all different sorts of scales. For instance, if you look up at a clock on the wall, you’ll notice that as you first look at it, the second hand seems to be frozen in place, then after a moment proceeds to move normally. That’s because the brain pays more attention to new stimuli.”
