Reaching absolute zero and BEC

Click For Summary
Reaching absolute zero is theoretically impossible due to the laws of thermodynamics, which dictate that a system cannot be cooled to absolute zero. Bose-Einstein condensates (BEC) occur at temperatures close to absolute zero, where particles occupy the same quantum state, demonstrating unique quantum phenomena. As temperatures decrease, particles lose kinetic energy, leading to the formation of BEC, but absolute zero remains unattainable. The implications of achieving absolute zero are largely speculative, as current scientific frameworks cannot accurately predict the behavior of matter at that state. Thus, discussions around absolute zero and BEC highlight fundamental limitations in our understanding of physics.

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."
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
