Stephen Hawking's concept of an
Event Horizon refers to the gravitational boundary limit of a Black Hole as it relates to photon (light) behavior. The characteristics of matter/energy at the
Event Horizon can actually allow matter/energy to escape from a Black Hole.
The bigger the Black Hole, the greater the surface area, and therefore the greater the radiation emitted. It is surmised by Hawking that there are practical limits to the size (mass) of a Black Hole, and this has led to further conjecture about Worm Hole's, and their role in this space-time interplay. One might consider that Worm Holes are the Glass Optical cable God uses.
Light energy, while having measurable mass, is still going straight; it is space that is curved, but we just don't conceive of space that way. Therefore... the next time you use photons to send your musical signal through a glass fiber, rest assured that they are
neither analog or digital in character when they are in transit through space time. At any one finite moment in time, it is impossible to predict where the photon is, or it's physical properties at that instant.
Space is a state of mind over matter. Sid... Please pass the fiber over to Timothy...
