I am so intimidated right now...I think I understand less about relativity now than before I asked the question. I think - if I understand things as written - that time can be observed to slow for an ...

Tracking time is one of those things that seems easy, until you really start to get into the details of what time actually is. We define a second as 9,192,631,770 oscillations of a cesium atom.

Time can appear to move faster or slower to us relative to others in a different part of space-time. That means astronauts on the International Space Station age slower than people on Earth. The ...
