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.

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 :( .
