Vibration is a rate or a level of energy.
All matter is energy in motion.
The level of vibration determines the form that energy takes as matter.
As the motion or vibration of energy decreases, it materialises as matter.
At a low vibrational rate energy becomes matter.
Gas has a higher rate of vibration than liquids.
Liquids have a higher vibration than solids.
We rate matter as a solid, liquid or a gas according to its level of vibration.
The lower the rate of vibration the less its energy is apparent and the colder matter appears to be.
At absolute zero there is no apparent vibration.
However this is a theoretical infinity that is physically unattainable because energy or matter without motion is not actually possible.
All vibrations of energy are the product of their frequency & wavelength of motion.
