In SR, an event is a particular point in space and time.(adsbygoogle = window.adsbygoogle || []).push({});

For simplicity, we only use one dimension of space.

We have x'=γ(x-vt) if when x, t = 0 , x', t' = 0

Let's say we have a bunch of inertial frames, all moving at different speeds, but all sharing a common origin x, t = 0

From the POV of one of the inertial frames, we have a series of events in spacetime with the coordinates (x1,t1) , (x2, t2) etc.

If we switch to another frame, the space-time coordinates will be transformed.

How do I describe this set of events in a manner that is independent of any inertial frame?

What about describing a continuous set of events, such as the continuous existence of the entire length of a rod that is floating in space?
