Firstly i am not a physicist, so kindly go easy on me.
So i grew up believing that absolute zero is the bottom of temperature chart. Recently i read that scientist achieved the feat of going below that mark.
According to what i know the molecules stop moving at absolute zero, and hence one cannot go past that temperature mark.
So my questions are:
- are these results are real or there is some other meaning they are implying?
- How is it possible to achieve temperature below absolute zero?
- theoretically what is the highest temperature one can reach, if the highest speed a molecule can reach is speed of light? (considering movement of molecules determine their temperature).
PS: I have read the related links/similar questions and duplicates, but couldn't understand it really. So please be kind enough to explain in layman terms, and please edit the question if there are any misconceptions.
