Zero-point energy in Classical and Quantum theories.

Zero-point energy (ZPE) is the difference between the lowest
possible energy that a quantum mechanical system may have,
and the classical minimum energy of the system.
https://en.wikipedia.org/wiki/Zero-point_energy

a)  quantum mechanical system
b)  classical mechanical system

Two different systems.

Unlike in classical mechanics, quantum systems constantly fluctuate
in their lowest energy state due to the Heisenberg uncertainty principle.
https://en.wikipedia.org/wiki/Zero-point_energy

a) Atoms of ''classical mechanics'' at 0-K  (-273°C ) are totally devoid
of kinetic energy and cannot fluctuate or move.
b) Quantum particles at 0°KELVIN (-273°C ) have movements and vibrations .

Two different objects.

"3. When it comes to associate the cold state of Kelvin temperature with force, scientific opinion is that cold temperatures are the opposite of energy and are considered to be non-usable. Furthermore, cold temperatures are identified as Entropy: meaning a negative force that works against energy rules of efficiency. In cross-reference, cold is the opposite of expansion: it causes contraction. The effects are: mass shrinks and the structure of molecular motions slow down. In turn, cold temperatures emit a negative force that affects an operational system, which becomes inefficient." Jagg

Cold is the absence of heat. In what "scientific opinion" do cold temperatures emit a negative force?

a) the cold state = 0°KELVIN (-273°C / -459°F) is absent of heat.
b) the cold state = 0°KELVIN (-273°C / -459°F) is packed with
'' negative virtual particles'' that can appear as real particles:
Casimir effect, Lamb shift, vacuum fluctuations.

Virtual particles are too fleeting in their existence to provide a usable source of energy and they add nothing to the Kelvin scale.

New Scientist creates a Crisis-Anticrisis Pair
==
“There are people who think that, using just the power of our minds,
we can understand what dark matter is, what quantum gravity is,”
says Arvanitaki.
“That’s not true. The only way forward is to have experiment
and theory move in unison.”

'' . . .  if you play by everybody else’s rules,
you will make the same mistakes.

If you want to make a difference, you must be willing to accept
that people ridicule you, criticize you, and shun you.
Turok wasn’t prepared for any of this.
It had not even crossed his mind. ''
