So Neiteio, please explain to me How the heck does energy take up more space than matter. I've asked this like 3 times already.
"Energy" used colloquially can mean an EM wave or a plasma. Both forms take up more space than solid matter, but only a plasma forms a phosphorescent blob (and has familiar atomic particles, the same types used in the Pokemon's body).
The more internal energy a substance has, the more wildly the particles will move. In solid matter, the particles have the least amount of kinetic energy which is why they are the most densely packed: the particles don't have enough energy to break the intermolecular forces (think gravity).
When the solid has absorbed enough heat (energy), the particles gain enough energy to break free of the intermolecular forces, which allows them to shift around more easily.
If the liquid absorbs a lot more heat, it becomes a gas. The particles have enough energy to fly around wherever they "want". They can travel further than the rigidly-locked solid particles, which means that there is more empty space between them.
A plasma (energy) is made when the gas particles absorb even more heat and the particles rupture- the electrons and nuclei split, which multiplies the number of particles involved.
