Does Spacetime Always Remember Events?

Click For Summary
SUMMARY

The discussion centers on the implications of relativistic physics, specifically regarding the synchronization of clocks between two particles, A and B. When B moves at high velocity while A emits a light signal, the time taken for the event to reach a target differs in each particle's frame due to the principles of special relativity. This leads to the conclusion that all events exist in a timeless manner across different inertial frames, with the Lorentz Transform serving as a mathematical tool to relate observations between these frames. Ultimately, the discussion asserts that all frames are equally valid, providing consistent coordinates for events without altering the fundamental nature of the observations.

consider A and B particles synchronizing clocks. Immediately after that B flies off at high velocity at the same time A flashes light perpendicular to B's motion. It hits some target c. Now in A's frame the event happened after t_{a}=perpendicular distance/c. But in B's frame it happened after t_{b}=hypotenuse/c evidently t_{b} being higher. Does this mean all events exists always and there is always a frame which is yet to witness anything ever happened?

All frames are equally valid. There is nothing that one frame will provide a witness to any observer that another frame won't. Any event that you want to consider in one inertial frame can be transformed into any other inertial frame using the Lorentz Transform. But this doesn't mean that an observer can see anything differently just because a different frame is used. Frames just provide a consistent way to establish coordinates to things that happen.
