r = √((2GM)/(ve2))
I plugged this equation into a spreadsheet, and got a different answer from what you got.It looks like the "√" is missing when you do the calculation?
It is a shame the air was not denser up top, you would need less speed to escape. I have to say I do not think your calculation has anything to do with an event horizon, it seems to me it is the thrust needed to push against the less dense air up top. More speed is more thrust.
Yes, you could theoretically climb a sufficiently high set of stairs to leave the Earth's atmosphere without reaching escape velocity. That's what a hypothetical "space elevator" would do. However, that's not what escape velocity is about. The escape velocity is the minimum speed that an object has to travel at for its momentum alone to allow it to escape an object's gravitational field indefinitely. In other words, it's the minimum speed that you'd have to push something to so that it never comes to a stop and then falls back to the Earth.
I would of though it would have to be a continual force rather than a speed to escape a gravitational field.
All BH's are finitely dense?
There is finite mass in the observable Universe?
How can you detect a BH if they do not emit light?
How do you know BH's are just not a body that is black in colour?
Relativity predicts an infinitely-dense singularity at the center of a black hole.
How can something be infinitely dense without being infinitely large?
I would of thought absolute dense existed but not infinitely dense which sounds rather strange.
Could a BH be transparent?
An infinitely-dense object need not take up any space in order to have a finite mass, so there's no reason to say that it must have a size at all.

You dont seem to understand the difference between density and mass.

You dont seem to understand the difference between density and mass. Yes I do , do you? Yep, that is why I commented on your post. Also, your made up equation 'Dmax = V(k) - k where k is space and V is volume' what on earth is that supposed to mean?
not dependent on, conditioned by, or relative to anything else; independent: an absolute term in logic; the absolute value of a quantity in physics

Try it this way R³ = 1m³R³ - R³ = 0k = D max

Try it this way R³ = 1m³R³ - R³ = 0k = D maxIt is not that it is hard to understand. When you say k=space, what exactly do you mean by that. Also, the next equation you made up, what does R stand for, what does m stand for, how do you know that R³ - R³ = 0k (by which you mean from the previous 0 space I think. How does this actually relate to density?
