No, it's an intrinsic property of all photons.As an observer Is the spin part of the photons energy?
A photon's energy is given by E = hf, where E is the energy, h (actually h-bar, but I don't know how to type that) is the Planck constant and f is the frequency.How much energy is in a photon?
Google cramer and transactional interpretation of QM if you want some sort of thinking along these lines.If a photon leaves it's source and it is not affected by time and space at which point I absorb the photon, does it therefore imply that the source had interacted with me. To further develop my question so that you understand what I am thinking. The source is in a way passing it's energy directly to me. In a way I am interacting with something that existed possibly millions of years ago.
If you interpret the question as whether the change of position or time elapses from the photon's perspective, no, it doesn't. This has interesting consequences, and I believe is one of the prime reasons for many of the peculiarities of light as seen from our perspective in which distance and time DO elapse in our observations of light. (Double slit experiment, etc.)Does a photon experience time or space? I have follow up questions for your answer
The double slit experiment is the result of wave-particle duality. You can perform the double slit experiment with electrons onto phosphorous paper and get the same result. There's nothing special about light.If you interpret the question as whether the change of position or time elapses from the photon's perspective, no, it doesn't.

A boson is a particle which:maverick I wish you could provide me with an intuitive easy answer. On the other hand I have avoided understanding things based on their difficulty for far to long and am pulling up my sleeves and going to work. Gotta start somewhere right! Now what do you mean a spin 1 boson (I know what it means to propagate). Also because of the law of contraction, if light is a particle would it be two dimensional (our perspective). Is it possible for us to view/measure a single photon?
P.S. I will be asking a lot of questions as I have so many of them.
Modeled as a particle, a photon is a point, i.e. zero dimensions.Also because of the law of contraction, if light is a particle would it be two dimensional (our perspective).
Yes, using a photon detector.Is it possible for us to view/measure a single photon?
I understand all of this. When I think of looking at a black hole I think of the first visualization you listed below, however I am not thinking of it as a record player, more as a whirlpool that if you moved the center of the whirlpool would seem to move with you. Thats if the blackhole is not spinning or anything.Well a spaceship going near the speed of light will appear to contract (lorentz contraction) in the direction of its motion (your vantage point is irrelevant). So, for example, if you were to be directly behind said spaceship you would not notice any contraction at all since it's only contracting length wise (not width wise). i.e. if you're watching the U.S.S. enterprise do its silly warp speed animation and you're looking at it from the side it's going to contract, however, if you're staring at its butt from directly behind it you wouldn't notice anything since that's not the axis through which it is approaching a speed near c relative to you.
A black hole is also in no way 2-dimensional, spatially it is 3-dimensional in extent. It's not like a vinyl record that you could look at on edge it is a sphere.
Thanks for the source on the accertion disk though this wasn't really what I was imagining.I imagine the confusion over the shape of a black hole (assuming I understand your visualization correctly) is because of images like this: http://lgo.mit.edu/blog/drewhill/files/blackhole.gif [Broken] however, general relativity exists in 4 dimensions, 3 spatial (x,y,z) and time however one cannot draw a picture of time however that is what these illustrations are trying to do. As you see the 2d grid fold it's not folding relative to the 3rd spatial dimension but in the temporal dimension. In other words the z-axis in these pictures is not in meters, it's in seconds. It's an attempt to visualize a 4-dimensional object in 3-dimensions.
Or maybe you're visualizing this http://thesamerowdycrowd.files.wordpress.com/2008/12/black-hole.jpg which is showing an accretion disk around the black hole (the hole itself is not flat like the plane of the accretion disk). For an explanation of why accumulated dust and such in space tend to form these 2d planar disks I'll simply refer you to wikipedia http://en.wikipedia.org/wiki/Accretion_disk
