Experiment shows that "arrow of time is a relative concept, not an absolute one"

[FluidSpaceMan]

Regarding the temperature of a black hole. There is a way it is calculated based on the predicted Hawking radiation correlated against standard black body radiation. The larger it is, the colder it is. Small black holes, like the ones feared to be produced by the LHC, would be quite hot, and evaporate in a burst of radiation.

I believe gravity would still be attractive under a reversal of time. The distance an object falls being proportional to 1/2 a t^2, if the time interval is negative, the direction of the motion does not change. After all, we know the Earth has been orbiting the sun for a long time so reversing the arrow of time we would expect to see it just orbit backward. If it flew out of orbit instead, the theory would be wrong. But I am all for anti-gravity, so I can finally get that hover board.

Perhaps in an antimatter universe, moving backward in time, entropy would increase as time progresses backward. But would we be able to tell the difference between that universe and our own if we were living in it?

Thanks, im now reading Hawkings Radiation.
LHC black holes evapouration.... aka gravitational constant requiring a tipping point to mass/gravity/energy to produce a black hole to a point where it is energetic enough to consume energy(im stopping short on speculating the concept of black holes only being able to exist where there is matter to be consumed as thats outside my current reading)

Re Time, the human animal tends toward an entropic perspective on atomic structure of the biological expereince...
do we really know what time is ? Vs repulsive forces ?

anti-gravity is like screaming free chemical weapons for terrorists in this capitalistic world economy.
one world gravity ...
gravity(global)-lisation...

look at the biggest most respected model companies exploiting lesser human rights laws to further their basic model for economic sustainability.
why should the individual citizen be held to a higher moral law ?(etc...)

anti-matter universe...
i wonder if time is relatively constant in a directional format for evolution, be it matter or anti-matter, is it logicaly possible for highly advanced intellectual beings to destroy themselves and/or render themselves consciousely into something vastly lesser than their level of intellect(ignoring humans escapism concepts).

can a wave create a photon ?
thus a wave of increasing or decreasing magnitude create variant photons... ?

pondering on the unified field potential the black hole simply squeezes space like a membrane which in turn occilates the wave form creating both inward and outward pressure.
The force required to create the black hole being relative to the amount of matter it can obtain to increase or decreaseits energy.

pictorially, imagining a flat circular sheet.
pushing in the centre creates waves going outward, however... that same pressure also creates waves moving inward...
the greater the mass close to the centre, the more energy it gains to pull into the centre.
this suggests a unifield field theory ?

funnily enough I'd been considering the Particle Waveform duality of Light. A simplish way of explaining the two is with a Tissue. When you have a sheet of tissue we can say it represents spacetime, if you were able to flap it (Perhaps hold it by two corners horizontally and blow along it's length) you can make it wave. However should you want light to behave as a particle, you have to twist that tissue paper. twisting it alienates from the the flat spacetime that the wave functions on, creating a packet/particle.

This would suggest that light as a waveform wouldn't necessarily propagate well across a vacuum, however the particle (twisted alienated version) would be it's own system and be able to transport across it.

Light speed would have no variation when it comes to the waveform variety, however the particle version could have variance. Both would be effected by gravity.

A light wave has no problem propagating in a vacuum, because it is not a wave of a transport medium.

"For electromagnetic waves, propagation may occur in a vacuum as well as in a material medium. Other wave types cannot propagate through a vacuum and need a transmission medium to exist." - https://en.wikipedia.org/wiki/Wave_propagation

Light waves do slow in a medium.

"The refractive index can be seen as the factor by which the speed and the wavelength of the radiation are reduced with respect to their vacuum values: the speed of light in a medium is v = c/n, and similarly the wavelength in that medium is λ = λ0/n, where λ0 is the wavelength of that light in vacuum." - https://en.wikipedia.org/wiki/Refractive_index

LiKe !

some years back i had been stumbling on the theory of hyperbola wave function to create photons as a process of matter creation.
i am unsure if there has been any work done to try and acertain a working theory.

my theory is that the "x" (intersecting point) of 2 waves created a Paralax Hyperbola photon

possibly the actual creation of te photon is outside the expected range of the intersecting waves and may bend and shift.

imagining holding a stick in each hand/electrical wire/or anything....
and the wave function being transmitted along that line.
as you put the 2 ends of the sticks closure together the wave function arks like electricity between the 2 points.
however, not in a straight line between those 2 points, or in a price curve.
and... further more, when it does, the actual point where it intersects and creates the "x"/photon may shift and move.

if as you say we are looking at the tissue as a flat object making waves and wondering why it is not behaving as a flat object, because it is actually twisted AND potentially flat at the same time...
co-existant properties of co-existant observable & creating & converting functions ?

just a theory
im very much liking your idea !

---

soo...
as you say twisted
then blowing on it
the observable data is being recorded as a wave coming out of a flat line
but the actual property is twisted
maybe gravity is the end point of the twisted tissue and the photon is the measurable flat line of the flat plane.

blowing on the twsited tissue makes gravitational waves ?
however we only can scientificaly measure the wave function after it has been created
and
only the photon after it has been created...

hhmmm...
