So the idea is to assign a different "time" to each event. It's very different from physics, because physics assigns the "same" time to multiple events.

In Newtonian Mechanics, everyone agree to assign the same time to the same collection of events.

In Special Relativity, the same time is assigned to different collections of events by different observers.

In General Relativity, it's more complicated.

>>> *Every event happens in a place.

Does each event get a different place, of places can be shared between events?

The t coordinate of 4D Minkowski space-time perfectly corresponds with the definition that the GP was making. As does the t in Newtonian mechanics.

> Does each event get a different place, of places can be shared between events?

Why is this even a question? It is obvious from the definition that two events can happen at the same place at different times.

The theory instead (wisely) says nothing about events happening at the same time.

I agree. In Classic Mechanic "time" an be just t (or an opaque container with t), but in Special Relativity you "time" as defined by the G...P must be (t,x,y,z) (or an opaque container with (t,x,y,z)).

> Why is this even a question?

It's very strange that two events can not share the same "time". This is not the usual definition of time in physics [1]. So it's a natural question if the same strange property apply to "place".

Also, the definition of "time" in a world with special relativity makes it necessary to include (x,y,z) so "time" includes all the information included in "place". Why is it necessary to have both concepts?

[1] I think it gets more complicated in General Relativity, but I never took that course :( .
