    Hello,

    The followings are some aspects related to "absolute zero":-

    In this respect, I have few questions:-

    1. How form or state of any substance can change at "absolute zero"?

    2. How properties of sustance can change at "absolute zero"

    3. Can all substance degenarate at "absolute zero"? If yes, in what form?

    4. How a substance can exhibits unusual properties including superconductivity, superfluidity, and Bose-Einstein condensation at "absolute zero"?

    5. Whether anf fundamental force out of four fundamental forces or any particle out of elementary particles exhibit properties similar to properties of any substance at "absolute zero?

    Best wishes.

    How force/energy can be in/as straight line instead of wave like? Whether any force can be shown its movement in straight line or with no vibrations?

    -For #1, I don't think you can change the state (I'm assuming you're thinking of solid/gas/liquid) because a bosonic/fermionic condensate is a state itself and so that IS the state, and can't change unless it is no longer in absolute zero.

    Any serious discussion of absolute zero must rely on the official science definition, which might be different than someone's popular memory of what it means.

    We should research and understand the official science definition, then recognize that some physical activities are barred from happening at A.Z. but some other things are OK.

    State change can be from gas to liquid to solid. It can also be form or structure change i.e. from substance to molecular to atomic to subatomic to energy/force . Upto what extent state can change at absolte zero. Can change in temperature degenarate any substance to force level?

    How magnetic fields/forces, gravity, inter-molecular forces, intra-atomic forces, gravity of substance etc. are effected at absolute zero and with change in temperature?

    Whether intra-nuclear forces still exists at absolute zero?
