Can Information Escape A Black Hole?

The black hole information paradox is a physics problems that strikes at the heart of one of the crucial problems in modern physics: the fact that we can’t reconcile general relativity and quantum mechanics. And it is all black holes’ fault.

if they get bigger, do they get less dence? or is the density in every black hole the same?

Umm, if nothing can escape a black hole, including light, then explain X-ray bursts which are a spectrum of non-visible light. It may be those X-rays that are the missing information or the pathway. Now a question. Why is it 'only' theorized that all galaxies have a supermassive black hole at the center? What is the galaxy orbiting otherwise?

There is no black holes. Most people don't know that Einstein said that singularities are not possible. In the 1939 journal "Annals of Mathematics" he wrote -
"The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of General Relativity predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters (star clusters) whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light."
He was referring to the phenomenon of dilation (sometimes called gamma or y) mass that is dilated is smeared through spacetime relative to an outside observer. It's the phenomenon behind the phrase "mass becomes infinite at the speed of light". Time dilation is just one aspect of dilation, it's not just time that gets dilated. A graph illustrates its squared nature, dilation increases at an exponential rate the closer you get to the speed of light.
Dilation will occur wherever there is an astronomical quantity of mass because high mass means high momentum. This includes the centers of very high mass stars and the overwhelming majority of galaxy centers.
It can be inferred mathematically that the mass at the center of our own galaxy must be dilated. This means that there is no valid XYZ coordinate we can attribute to it, you can't point your finger at something that is smeared through spacetime. More precisely, everywhere you point is equally valid. In other words that mass is all around us. This is the explanation for galaxy rotation curves/dark matter. The "missing mass" is dilated mass.
Dilation does not occur in galaxies with low mass centers because they do not have enough mass to achieve relativistic velocities. It has recently been confirmed in 6 very low mass galaxies including NGC 1052-DF2 and DF4 to have no dark matter, in other words they have normal rotation rates.
