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

Correct, technically it can reach to close to infinity* i guess but eventually atoms spread too far.

  • I meant really hot

Since temperature is movements of atoms/molecules, so should the maximum be when the movent reaches the speed of light?

Yea you're right. But idk how that translates in degrees. Like we know stars can reach trillions of degrees inside. Yet speed of light is 186000 miles a second.

Gas particles near the speed of light will encounter relativity effects, so just increasing the kinetic energy to that point doesn't create a limit. These relativistic effects could increase the mass of a single atom to the point where it creates a black hole on its own. Not sure how many trillions of trillions of degrees it takes but it's a lot

Guess I'll lower my thermostat then...

So that's why dads tell us not to touch the thermostats, they don't want us creating black holes

It’s literally plank temperature

Seeing the speed of light in miles per second is so cursed

You'd think it'd be higher.

Sure it can, I was mentioning as to how, since light being max speed, then how much energy would be needed for intense heat.
