Can Hawking temperature be associated with a force?
« on: 25/08/2020 20:04:04 »
A stationary, massive object is assumed to impose a “force” upon surrounding space. The force may be called the “Hawking force” as it is associated with Hawking temperature. This force may be represented as a vector.

If one condition applies, and if the components are suitably defined, then the components will give the definition of Hawking temperature and length contraction.

"Can Hawking temperature be associated with a force?"
Not easily.
One is a vector and the other is scalar.

“Hawking force” as it is associated with Hawking temperature.
Without having read the attachment...

Hawking radiation does produce a force, but:
- The temperature is in the nanoKelvin range, so the force is exceedingly small
- The event horizon has a uniform temperature, so the force is equal in all directions, so there is no net force on the black hole
- A nearby object will feel an outward radiation pressure from the black hole (at a temperature of nanoKelvins), and a radiation pressure from every other direction due to Cosmic Background radiation at 2.7 Kelvin. The latter overwhelms any radiation pressure from the black hole (by a factor of billions)

The inwards gravitational force of the black hole overwhelms the outward radiation pressure from the black hole by a factor much larger than billions.

The quantization rule states that only an integer number of waves may be imposed upon a
circumference; nλ = 2πr
seems irrelevant to Hawking radiation but an integral part of the derivation.
You also have a problem in beginning with a vector and ending with a scalar, as BC pointed out. Your argument loses its direction early on, where the force vector mysteriously loses its direction. 

But full marks for neatness, as usual.

It says
"A condition is required for emission; A1 = A2 "
Why?
