Came across this video today, in which a whole bunch of scientists are talking about zero point fields, and since your knowledge on it was not great, I thought you'd be interested in what they are saying.
My only objection is that one scientist distinguished reaching zero temperatures as possible, so long as you can do it in an infinite amount of steps, which is just garbage to say the least, infinity is not a number, its a concept. And they don't exist.
As you will see, I was correct in what I told you, you cannot reach absolute zero and even in the ground state, there is motion. Motion still translates in this sense, that there are non-zero temperature contributions.
