Yes yes the internet is awesome!

I guess that must the instantaneous watt? E=mc2 tells us there is 100x more energy in that mass. How does that work? (internet free brainstorm while watching expedition Robinson)

Yes, it must be the instantaneous wattage which would climb to infinity as the mass evaporates and the remaining life goes to zero.

I think I'll keep my distance!

And this one: why doesn't the bottom fall?

A family that plays together, stays together.
My guess is it does not have enough kinetic energy. You can put the motion in Lagrange's equation and solve.
The restoring force of the spring counters the gravitational force, methinks.
Ponderomotive force?
Cognition at a distance?
Neglecting gravitational effects of nearby wormholes, the ball spends more time in the regions of higher potential energy (hills) than in those of a lower energy (valleys). The energy difference has to go somewhere - into kinetic energy of the ball motion. Friction doesn't play any role. (It's somewhat reminds me of a ponderomotive effect.)

so does a bouncing ball!

I know, but I can't help it. I used to be a solid state physicist and solid state physicists describe electrons as balls. When I left physics, my perspective has inevitably changed and now every time I see a ball I think it's an electron.

When you thinks of balls, are they necessarily on fire?

It's only natural. Electrons are in charge.

So much negativity, what?

From negativity comes magnetism through an ODE to cathodes.

Always on fire. Heavy mental this is.
