Semi retired old time computer nerd who started programming on a Commodore Pet.

Since I'm also active in the Physics forum I should add that I started as a theoretical chemist, moved into solid state photochemistry and finally worked in industry as a colloid scientist. I only became a full time computer nerd in 1997.

I've read through this several times, but I'm afraid I still can't work out exactly what you're asking.

comment How does Gravity behave at high energy?
@SachinShekhar: yes it does, but that's just saying the curvature is dependant on the stress energy tensor - kinetic energy appears in the stress energy tensor as a momentum flow or a pressure. To be surprised at this would be like being surprised that increased mass causes increased curvature.

comment Can a quark irreversibly pass though an event horizon?
I saw your later question first, and I think my objections to the later question apply to this one as well.

comment How does Gravity behave at high energy?
@SachinShekhar: unless you consider quantum effects there is no mechanism to change the value of $G$. Quantum effects certainly will change $G$, but of course we have no theory of quantum gravity so we can't say exactly how it would change.

You are seeing water vapour evaporating from the hot potato, and then condensing as it cools to form water droplets.
