Interpretation of Relativity of Simultaneity

[lowerlowerhk]

If relative simultaneity implies that one event that could be already measured w.r.t. one reference frame not yet measured w.r.t. another reference frame:

then could one find an reference frame at which none of the events were measured?
If such reference frame exists, could one observe the universe from its beginning?

 

[Chestermiller]

Simultaneity refers to two events that are observed from two different inertial reference frames. As far as single events are concerned, all single events are observed in all reference frames.
