Is it possible to reach absolute zero?

    So, from what I've heard, absolute zero is 0 Kelvin, lowest temperature possible, -273.15 C, etc etc.

    Is it possible to even reach it? Why or why not?

    Google "absolute zero" and you'll find some detailed info. The Wiki page is surprisingly good.

    Absolute zero is forbidden by the Heisenberg uncertainty principle.
