The discussion centers on whether a Bose-Einstein Condensate can achieve absolute zero (0 K). It is argued that while the cooling method can approach this temperature, it cannot reach it due to inherent limitations, such as the presence of heat from imperfect insulators and the nature of the cooling process itself. The concept of absolute zero requires zero entropy, which is unattainable in finite systems. Additionally, there is confusion about how temperatures in the nanokelvin (nK), picokelvin (pK), or femtokelvin (fK) range are defined. Overall, the consensus is that absolute zero remains a theoretical limit rather than a practical achievement.

To reiterate the question, can the method of cooling an object down with the Bose-Einstein Condensate reach absolute Zero?
I believe it cannot because the method itself might be close, but never achieve because i believe that absolute zero can only happen naturally, if it can happen at all. Bose-Einstein condensate was made by using a magnetic field to "naturally" separate the hotter parts of the atom to the colder part, and as the atom gets colder, the magnetic field is pushed downwards so, even in the coldest part of the atom, the hotter part leaves. However, since this is artificial, measuring this object and the presence of a imperfect insulator will give off heat and, therefore, break the brief state of Absolute Zero, if it was achieved.

I am not sure if this is the reason... so if someone can inform me! Please help! :smile:

No physical system can exist at absolute zero. That requires the entropy to be zero as well, and since the system is of finite size, it cannot have zero entropy.

I'm not sure how nK, pK or fK 'temperatures' are assigned to these systems.
 
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...
