No, because the Third Law of Thermodynamics says you can’t get there
anyway.
How close can one get?
Arbitrarily close. I heard of experiments already being done in the
microkelvin range.
Odd. So absolute zero is the "limit" and we can get arbitrarily close to
it? Kind of reminds me of the infinity in the unit fractions. Say they
are signed for a moment... ;^)
