Summary

Interesting Things with JC #1673: "There Is No Universal Now" – A star 100 light-years away is doing something at this moment, but observers moving at different velocities can assign different times to the same distant event. What appears simultaneous to one observer does not appear simultaneous to another, and the universe continues without a single present moment everyone shares.
