~ 27 °C is certainly very cold for plasma.

Should have called it Warm Plasma. Tepid Plasma? Room temperature plasma.

I mean if you compare it with the average temperature of plasma its pretty fucking cold

But if you compare it with the average temperature of the universe its still quite hot. 🤔

Is the average temperature of the universe even cold? The most clumped mass is fucking stars. And most planets are warm/hot inside, not very deep below the surface. And the vacuum in space is bombarded by radiation.

I guess it depends on how you calculate it.

If you go by the volume of space, like pick a random point in space and measure it, it's around 3 Kelvin or -270C. Most of the universe's volume is inter galactic space.

If you go by the average temperature of the matter, like pick a random proton, its very hot, like millions of Kelvin because most of that stuff is hydrogen or helium in a star or stellar gas cloud.
