УНН News of the World ✎ Europe expects heat up to 40 degrees due to a heat dome. Experts warn of infrastructure unreadiness and the danger of
tropical nights.
With the disclaimer that antimatter stuff is way beyond my proper physics knowledge, my understanding is that it does not. In fact, antimatter seems to behave pretty much exactly the same as regular matter in every way we’ve tested, it’s just that when it touches regular matter the two violently delete each other from the universe
Depending on what you deem “temperature”, that is actually possible :) The physical definition of temperature is the derivative of energy with respect to the entropy. With most physical systems, like gases, if you put in energy, the entropy increases. This happens because if the energy is not bounded from above, the amount of individual states the matter can take always just increases. So the temperature is positive. If the system has a maximum energy, as it can be constructed in some nanophysical systems, the number of reachable states may decrease towards the maximum. So, if you’re in this area, your system technically has negative temperature.
I’m afraid that if you ever have a temperature of negative Kelvins, you have somehow invented new physics
C > K
40 C is actually 313 K
Does antimatter have antitemperature?

Oh fuck… The entire of Europe is now on fire, the Atlantic ocean and Mediterranean ocean is now boiling… Sorry

Huh, neat. I was never very good at thermodynamics
Don’t worry about it the Universe takes care of it for you.
