Are you saying space is a fluid?
Maybe "an incredibly complex substance"
exhibits some characteristics of a fluid?
I should say "characteristic" impedance is 377 Ohms. It also has a
permitivity and permeability of 1 ;-)
I'm sure you mean relative permittivity and relative permeability.

No, this is not correct. The permitivities and permeabilities of all
materials are relative to free space. Free space is assumed to be 1 and the
other values are relative to it.

The characteristic impedance is the square root of permeability divided
by permittivity, so if both are one, the characteristic impedance would
have to be one.

No, this is not correct.

Wow. Sometimes even this newsgroup surprises me.

Since this thread started on the premise that a photon is a particle,
which it clearly is not, what did you expect?
