If we increase the temprature of a body so much that its wavelength becomes lesser than the plank length, the quantum nature could breakdown as the wavelength of the particle is lesser than the so clained least possible length.
So my question is ...
How the particle will behave when it will go through such a transition?
does it mean that the existence of such a particle beyond this temperature collapses?
or it enters into a whole new state of matter where the particles behave entirely different like BEC?
