Light acts as light does.

We find it convenient to describe light (electromagnetic radiation) as a wave-particle duality...

I don't know.

Ah, I've just thought of a reason why. If the photon can't escape from the
black hole then that also means it cant travel. It's in the travelling that
a photon reverts to a wave. Does this mean then that once the photon passes
beyond the event horizon it become totally static. Or, since it is travelling
as a wave when it passes beyond the event horizon it continues on and eventually
becomes dissolved in the singularity. But would it not collide with other
particles whilst travelling inside the black hole so revert back to a photon?
Well, if it does collide with other particles and reverts back to a photon
then both it's duality properties are unable to escape. Even further to this
another reason could be that all matter drawn into the black hole has it's
structure so changed that they all become bosons. If I'm correct then boson
type structures do not interact with one another and since the photon is
also boson then has nothing to interact with so enabling it to revert from
a wave back to a particle. Perhaps it's in the black hole where one will only
ever find the Higgs-Boson. Oh well, most probably a whole load of rubbish
written here by me but it's great to be able to let the mind wonder a bit.

That's because it does behave in both ways.

Nothing travels. The photon is a disturbance in the electromagnetic field. In a stadium wave nothing travels--just a ripple of local conditions.

The question here then, Will'; is why can electromagnetic radiation escape from
a black hole but not light in the form of electromagnetic radiation though?
..it could be that we're missing something obvious here?

Nothing physically travels from one end to the other, but there is movement of individual components that gives that "effect".

Ok now consider the effect of throwing a stone into a lake. There is a ripple effect outwards, water doesn't move at the point where the stone was thrown in, but water does move at the shoreline which could move small pebbles. Has energy travelled?

The water has moved, it's moved by displacement, displaced out equally
from the center where the stone first entered the water.

Of course it moved, that is a tsunami. But if you mean did each individual water molecule travel from the impact point to the shore, no. Try it on a scale where you can observe. Drop a brick into your toilet tank at one end. Does the water move?

The answer is Hawking radiation. Based on the tenet that information cannot be destroyed. This radiation includes photons and other "particles and bosons".

Hawking has taken a lot of flack for his theory, but he has won a bet or two based on others coming around to his point of view. Since it doesn't make sense it must be a Quantum effect.

Since i am not deeply conversant on the subject I will let you read what you can on the internet or at a library.

Actually I do not think that is completely accurate. The original formulations of Hawking Radiation resulted in the Black Hole Information Paradox (BHIP), and as I understand it the original bet by Hawking proposed the quantum information could be lost. Some years later he conceded the bet and modified his equations in a way that the information that was apparently thought to originally be lost into the black hole could be contained in Hawking Radiation... but I am not sure it was well received. One solution for the BHIP, was apparently resolved by Leanord Susskind’s, Hawkins rival, version of the Holographic Principal... that is my understanding in any case, as it relates to string theory. The Principal allows the information associated with particles that were absorbed into the black hole to be preserved on the surface of the black hole or the event horizon.... leaving the stripped information stored in two dimensions... there are some wild implications with this principal... like the universe being a holographic projection of two dimensional information projected from the cosmic event boundary at the edge of the universe.. But hey that is quantum physics...

Excellent summary.

One interesting example of the wild implications of the Holographic Principal is that quantum computing may well NOT be practical due the information density limit being exceeded by having multiple qubits confined into too small a volume.

Hence, whether or not you can pack multiple qubits together could prove or disprove the theory.


Myself, I am rather skeptical about the claimed quantum superposition states and I suspect there has to be 'hidden parameters' or additional localized dimensions at play...
