Gravity as we know it is a result of an imbalance of a density order...
Actually I think that makes sense. As we all know, according to general relativity and as opposed to Newton's concepts, gravity is not a force but an effect of the distortion of space-time caused by the mass of objects. I think such distortion of space-time may well be called an "imbalance of a density order" without it being pseudoscience, it's actually an interesting point of view, as to me. So, assuming we are talking under the paradigm of general relativity, the question here is: how long does it take for that distortion (imbalance) to propagate and affect it's surroundings?
Actually I think something odd: what if the speed of light wasn't constant but dependent on the density of the "media" it is traveling by? Because light is one thing, and another thing is the media it travels by, right? but.... what if that wasn't the case? what if what we call light, the waving electromagnetic field, is actually the media itself? So, is the speed of light affected by the gravitational field (read: space-time distortion) of the objects it is traveling next to?
Galileo used to think objects fall at a constant speed, because he could not sense their acceleration when falling from short distances, but Newton then realized objects actually accelerate when falling into a gravitational field. What if the exact same happens to light?
If gravity is no faster than the speed of light how come light can't escape from a black hole...
I think that's an interesting thought too. The accepted fact is that light is affected by gravity to a point where there's no escape, right? So, is it affected in a way different than the other objects would? I wouldn't think so. I'd say the speed of light also changes depending on the intensity of the gravitational field it is being affected by. So what is this gravitational field anyway? What is space-time? how fast does it travel? or... does it travel at all? because I would say it is the distortions (waves, pulses, etc) that travel, not the media itself. So, if the media does not travel, and gravity (whatever it be) is the media, then gravity does not travel, the distortions (density imbalances) in it do at an speed that depends on the intensity of the field they are traveling by.
