Why does time go so fast on vacation?
Why does time go so fast on vacation? This is called the holiday paradox, dubbed as such by psychologist and BBC columnist Claudia Hammond. Our brains register more memories when we're experiencing new things, which in retrospect feels like it all happened over a longer period of time.
Why do you age slower the faster you go?
That's because of time-dilation effects. First, time appears to move slower near massive objects because the object's gravitational force bends space-time. The phenomenon is called gravitational time dilation. In a nutshell it just means time moves slower as gravity increases.
