Another question about gravity in LT as a relatively short-range effect: what if the ranges of gravity and electromagnetism were swapped in the LTverse compared to our own?
Well... [this is your last chance to run away]
They have the same range. Both potentials are 1/r. (A short range potential is e^(-r)/r )
The reason we don't notice electromagnetic forces is the fact that there are 2 opposite charges that stick together so there is no net charge on larger scales, whereas there is only positive mass.
The electromagnetic force is way stronger than gravity, actually.
If you would swap the strengths, my educated guess would be that stable atoms wouldn't form anymore, everything would be plasma and the universe would be full of black holes. Not very nice
...putting this gently, are you perhaps trying to impose our real-world physics in the LT universe?
My question wasn't so much "how would our rules work in LT" as "what if [these rules] existed? how would that universe work?"
It's a gedankenexperiment. Roll with the crazy and see what emerges!
