As you said, speed is relative, so if I'm traveling on the ship, object a, and I fire a missile( I just remembered that bullets stop accelerating once they leave the muzzle), object b, then an observer on earth, object c, would only notice b accelerate to just under light speed and stay there, while on a I would notice b accelerating up to it's normal relative speed to a. but an observer on c would just see it accelerate to just under c? Your right that is a large concept to understand, but it has never been proven, it is all theory, not neccesarily truth.
And the point you make of relativity in terms of a point of reference to calculate speed doesn't answer anything, to put this idea in layman's terms I am reffering to the 'fabric of space'. This means that position and velocity are not based relative to other objects, but to the actual fabric of existence.Which would mean that there is some base speed of zero that is independant of every object in the universe. So for the limitation of the speed of light to exist, wouldn't all speed have to be set relative to this reference? So then an object travelling at .99C away from Earth could be travelling at 1.1C relative to the actual fabric of space.
To put that idea in a little easier to follow form, let's say that space is the ground, reaching out to infinity, and all the planets, stars, etc. are just cars driving in every which direction over the ground. Wouldn't the speed of the photon be calculated in reference to a point on the ground instead of one of the moving vehicles?
I hope that made it a little easier to understand.
About the black hole thing, I didn't think of that and it seems to make sense.
