How can we beleive in the Higgs Boson and think space has intrinsic properties?

Space impedance, once again.  I always get it mixed, myself, but it is still taught as an intrinsic property of free space.  But obviously, the capacity of the vacuum, as a holder of light, is the maximum compression the vacuum can handle before triggering the Higgs effect. Wiki says:

Since 1948, the SI unit ampere has been defined by choosing the numerical value of μ₀ to be exactly 4π×10⁻⁷ H/m. Similarly, since 1983 the SI metre has been defined by choosing the value of c₀ to be 299 792 458 m/s. Consequently

exactly,

Exactly? Only to the extant that free space gets pi, but since free space  capacity is limited, the precision of pi is limited.   The physicists are mad at me because I don't believe in free space. So they are on alert whenever my readers try to ask the simple question, how can free space hold anything?

Otherwise, they have already decided the capacity of light when they introduced the speed of light, so this is just a change of variable to electrical engineers units.

And they are using a sphere surface. What they really mean by pi is maximum divergence, there is no interference between the magnetic exchanges laterally, they are not curving.  What they get is the bandwidth of proton light that has escaped the proton, in reduced units. By reduced I mean all the common coefficients have been cancelled.

Anyway, free light is free because it escaped a proton. So free light will not have a Compton make a mass equivalent in free space.
