Oh dear - I thought it was actually the best (most understandable) bit
The reason I second guessed myself was that I could just hear the likes of you reminding me of lensing or some such. I meant to get around to explaining myself before the day was done but got busy again. Anyway, what I meant was that the fields follow the shape of space never encountering an edge that they might press against. Adding here that electromagnetic fields don't press against space at all, at all. A photon wouldn't get too far if it had to push space out of its way.
Further, as I was calculating the energy of a photon with a wave length of 10
-28 meters I ran through the value-units: eV, Joules, Kelvin, Wattever I discovered it had a value right at 30k when pounds were the unit, which brought to mind the folk song
30,000 pounds of bananas. I figured if anyone was curious they'd google the coal-scarred city. That's what I do instead of scratching my head now-a-days.
And knots are a velocity, not a distance - nautical miles are abbreviated to nautical miles
And what's worse is that I know that.
