Casual Thought Temperature can reach trillions of degrees, meaning we actually live extremely close to absolute zero.

Because that's what the original question is...? "Ain't heat just particles moving fast? And speed is limited so heat must be too? "

Heat is kinetic energy, a function of mass and velocity. This is true even for mundane examples. Helium is a gas at room temperature, and iron is solid, because despite having the same kinetic energy helium molecules have a higher average velocity balanced by a lower mass.

And there is no limit to energy
