When you encounter the familiar, time seems to constrict and when you acquire new knowledge, it expands. Neuroscientist David Eagleman explains:
Time is this rubbery thing … It stretches out when you really turn your brain resources on, and when you say, “Oh, I got this, everything is as expected,” it shrinks up.
That relationship between time’s elasticity and whether your brain is processing new information gets at why time seems to turn up the tempo as we age. As the world starts to become more familiar, we learn less and sometimes even seek information and experiences that fit within what we already know. There’s less adventure, play, exploration, creativity, and wonder to invite and engage with newness.
