I'm a layman in physics, but here is what I understand: What we see in the sky with naked eyes is a map of electromagnetic waves in the frequency visible to the human vision. But that kind of observation is too limited because as the universe expands, the light coming to us redshift to the invis...

This relates closely to questions such as Deriving Coulomb's Law from Gauss's Law and Does the Coulomb's law include more information than the Gauss's Law in electrostatics? My question concerns the nature of isotropy in field theory generally, and how determinism impacts on this. Here is the bac...
