- TL;DR Summary
- A long bus or a stick , vs a multi-car freught train with bendabikity around curves or an elastic rubber band
In 2 spatial dimensions we have the ability to see there’s 2 types of long vehicles : busses vs trains… Buses must yield when making a very sharp turn since the front to the back are aligned at all times . Freight trains can make much sharper turns the more the cars are small and the gaps between cars are “bendable” allowing curves and zigzags
Now in 1 dimension of space + time do we have the same properties as well, or do we have how it looks on space-time diagram ,
Draw a very very long bus accelerating from 0 to a very high relativistic velocity
Now draw a very very long elastic rubberband with some ability to stretch when forces are unequal ?
