Curious non-professional here.

Thought experiment that led me to the question: If we assume that at any given time there’s an extreme level of EM and gravitational waves propagating through some point within a cosmic void (a seemingly homogeneous “vacuum”): do the transient emissions form any kind of emergent field?

I understand the ever-present zero-point energy but that should be in absence of all else. I’m contemplating an emergent field formed by EM/gravitational traffic. Obviously this field is only as present or strong as the transient fields passing through this point under consideration.

Thank you.
