Is there any activity going on at absolute zero?No, because the Third Law of Thermodynamics says you can’t get there

Fun fact: there are actual physical systems with negative absolute
temperatures (I studied a bit of this in undergrad physics), but whether
starting from positive or negative, you can’t get to absolute zero from
either side.
