COMMENTS:
There are a few translational matrices that light goes through in those instances, from "kinetic" energy to "potential" energy, so to speak. Most cosmologists think that the energy crosses through higher dimensions for that brief interval. But it is basically inviolate at 186,000 mps.
A black hole doesn't only slow light down, it stops it completely. The medium through which light travels can affect its speed.
It's extremely complicated and not very intuitive. I learned quite a bit about it about 16 years ago but it's all a bit vague now.
I remember stuff like if one thing is moving NORTH (north loses its relevance on an Einsteinian scale but bear with me) at the speed of light, another thing is moving SOUTH at the speed of light. Their relative speed is not twice the speed of light as would be the case in a Newtonian system, it is merely.... the speed of light.
I suspect thc might be the man to clarify this for those who understand his explanation.
It's not often that I start drooling and feel like a complete retard, but this is one of those moments.
Okay, we all know that light consists of photons. Photons always move with the same speed c. When a beam of light (a stream of photons) passes through anything but vacuum, the photons strike atoms in the material and are destroyed, their energy is absorbed into the energy of the electrons, or the thermal energy of the atom. The electrons can then oscillate and create another photon with the same energy (or different) moving at speed c. This photon will strike another atom and the process will continue until the light has passed through the material. The delay between absorbtion of the old photon and emission of the new one, as well as the density of the material determine how fast light appears to move through it, but remember that photons always move at the speed c. It's kind of like stop-and-go traffic. Oh yeah, and from the perspective of a photon time is frozen.
Heady stuff. What about the effects of gravity on photons, thc?
hmm, Don't know that one off the top of my head. I have to go the the in-laws now but I'll get back to you after the holiday. Merry Christmas.
The best answer I have for this is that even under the influence of gravity it is constant. The light reaching us from all over the universe would be moving at a speed other than c if it wasn't and astronomers would've let the world know about that. If you ever went faster than c time would move backward for you. Maybe you could get rid of some of those grey hairs Cathexis.
Heh heh ... better grey hairs than no hairs, at my age. ;-)
What baffles me, then, would be why gravity would affect light from an angle (e.g., bending around a gravity well), but not in-line with its path (i.e., directly ahead or behind). That strikes me as inconsistent.
I'm still trying to figure out where the extra energy goes.
It isn't, contrary to what the system claims in its textbooks.
