Reaching absolute zero and BEC

[Vals509]

Why are we finding it so difficult to reach absolute zero and if at all we are able to achieve it then what are the implications of such a feat?
What relation does a bose einstein condensate have with absolute zero? (i know that we have achieved it but how does it happen as we lower temperatures)

A system with zero temperature is just as theoretically impossible in our current framework as accelerating a massive system to the speed of light. For this reason, one can hardly use our current framework to speculate about "what would happen."
