Warm objects actually do weigh more than their counterfactual cold versions haha. The stress energy tensor is the quantity to look at here.

- patcon 1y agoI feel like you have somehow found the least authoritative source for the wonderful new information provided... why did you choose that one? serious question, because I'm trying to understand your process (and yes, maybe gently challenging it, but unsure if I should, bc you are clearly knowledgeable in specific ways about this)
- neuroelectron 1y agoThanks, I appreciate it

Abstract: "According to the weak form of the equivalence principle all objects fall at the same rate in a gravitational field. However, recent calculations in finite-temperature quantum field theory have revealed that at T>0 heavier and/or colder objects actually fall faster than their lighter and/or warmer counterparts. This unexpected result is demonstrated using elementary quantum mechanical arguments."
