    According to GR, the mass undergoes compulsory collapse once the Schwarzchild radius, [euqal to the EH] is reached the collapse continues, but we cannot apply GR at the quantum/Planck level. Whatever state the mass/energy exists there [probably some energetic state I imagine] is unknown.
    The same applies of course at the BB.

    The diameter of the EH [Event Horizon where escape velocity euaqls "c'] is determined by how much mass has fallen below it.

    If you're are talking about what I think you are talking about, then I see no reason why not. Subatomic particles can exist as energy.

    Energy is not a thing. Energy is a property of a thing.

    A subatomic particle can have energy, but it cannot exist as energy.

    True to your first statement .

    To your second ;

    Disagree

    Particle energy is not the same as electromagnetic energy , which is a wave .

    Particle energy , is defined by me as this , speed and acceleration . Especially when they meet .

    The fundamentals of this Universe are wave , particle and space ( in no particular order ) . Which are infinite in their existence .

    Because none can manifest without the other .

    Many are both.
    Energy is not defined as acceleration. Acceleration adds energy to a system, and that energy must come from somewhere else. In many cases, you can define kinetic energy with e=.5mv^2.

    Because both exist .

    Right. So does the concept of love. But love (like energy) isn't a thing.

    Yes

    Based on the physical existence things .

    Energy is a property of a system, not a thing that has a physical, material existence.

    Matter and energy are two different things. This is elementary school physics.

    Sorry that you do not understand that. Energy is not a physical, material thing.

    Where does this " property of a system " originate ?

    Depends on the system. A rocket gets its kinetic energy from the mass of the exhaust being accelerated by the rocket engine; the reaction to that drives the rocket forward. A pot on the stove gets its thermal energy from conduction of heat energy from a burner on the stove.

    Again, that does not mean the heat is a physical thing you can extract from the pot. It is a PROPERTY of the pot and its contents.

    The heat comes from physical objects ; In all your examples . Billvon .
