One thought on “The Twin Paradox – 60-Second Adventures in Thought”

  1. From this video I get that Einstein believed and postulated that time is not a constant. Does this mean that on different planets time is relative to that on Earth. Does 60 seconds on Earth not equal 60 seconds ever where else in the galaxy? Why would age slow down if seconds, minutes, and hours are just a measurement of our existence?
