Straight line in spacetime
Dec. 29th, 2020 08:04 pmhttps://youtu.be/Cg2tOUTE2F4?t=711 - Sean Carroll says a straight line in spacetime is the line with the longest duration.
Hmm.... how does that align with the light travelling in a straight line, and the time stopping for it? (duration is 0, so....how is it the longest duration?)
