9.3.3 A Clock Story

Question 1

A Clock Story

Answer 1

• Since space and time are relative, measuring the space-time coordinates of an event is not a trivial matter.
• The coordinates of events in a reference frame can be measured, in principle, using a vast grid of rulers and observers with clocks.
• The consequences of special relativity are the result of the counter intuitive nature of time and space, not the fact that it takes time for light from events to travel to observers.
