Interpretation of Relativity of Simultaneity

Click For Summary
Relative simultaneity suggests that events perceived as simultaneous in one reference frame may not be simultaneous in another. The discussion raises the possibility of a reference frame where none of the events have been measured, questioning the implications for observing the universe from its beginning. It emphasizes that while simultaneity varies between frames, single events are universally observable across all frames. This leads to inquiries about the nature of time and observation in the context of relativity. Understanding these concepts is crucial for grasping the complexities of spacetime and the universe's origins.

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?

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.

Thread 'EPR revisited'

In an inertial frame of reference (IFR), there are two fixed points, A and B, which share an entangled state $$ \frac{1}{\sqrt{2}}(|0>_A|1>_B+|1>_A|0>_B) $$ At point A, a measurement is made. The state then collapses to $$ |a>_A|b>_B, \{a,b\}=\{0,1\} $$ We assume that A has the state ##|a>_A## and B has ##|b>_B## simultaneously, i.e., when their synchronized clocks both read time T However, in other inertial frames, due to the relativity of simultaneity, the moment when B has ##|b>_B##...
