I think it’s important to point out as well that there is a mesiarble difference between between the permittivity of free space and air. But to your point the difference is quite small: e_r air is 1.0006 whereas e_r freespace is 1.

While temperature and pressure do have an effect on e_r air I don’t know enough to say that net movement of the particles in one direction would have a measurable effect. My instinct is no.

Looks like lukewarm_ozone proved me wrong. https://lemmy.today/comment/13053868

A quick Google search shows birdshot has an effective rang on the order of 40 - 50 yards. Now, you still have to be competant with a shotgun, but the public perception of shotguns is generally skewed. They have a much tighter spread and longer range than movies and games would have one believe.

More give doctors the right to treat their patients

Mildly fitting though. “Ecological collapse is imminent; please buy more products.”
