    Fields Space Time
Click For Summary
Time and space are discussed as potential fields, but defining spacetime as a field is considered circular reasoning. Instead, spacetime is characterized as a manifold with a metric, which is a tensor field. The relationship between time, space, and fields raises questions about their implications for general relativity. The consensus leans towards the idea that spacetime's structure is fundamental and not merely a field. Understanding these concepts is crucial for advancing theories in physics.

TL;DR
Can time and space be thought of fields?
Can time and space be thought of fields? And if so, how can this affect spacetime? And then what would this mean for affect general relativity?

I have no idea what that would even mean, so I think the answer is no.

A field is something that has a value at each point in spacetime. So it would be quite circular to define spacetime as a field.
 
What we call spacetime actually is a manifold equiped with a metric, which is a tensor field.

In John Stachels words: "no metric, no nothing."

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##...
