> Because they are vibrating, a lot of that energy is being wasted in brownian motion. So the denser it is, the more your average vector is going to be toward more dense brownian motion as the particles interact and induce more brownian motion ... Seems pretty intuitive to me.

So this is why warm objects weigh more?

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

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."

I didn't know this, thanks for sharing.

This reads like a sarcastic quip so, sorry if it wasn't but, they do. Solve for m in E=mc^2 and see what happens when objects have more energy.
