3. Black hole discussion...

Are there "greater and greater" numbers of black holes being created? How do we know this?
---------------------------------
One thing I read is that in some of the things being detected, the energies being detected can't be generated by chemical or nuclear sources in nature (the magnitudes are simply too great of a difference). The only available source of energy able to generate this kind of energy that they are detected is gravity (that we know of, perhaps 'dark energy too may play a role here?).

Thus, besides being detected in almost all of the centers of galaxies examined, black holes have been detected when they collide together, w/ a new detector built in I think, Louisiana and Washington state. They had a show on PBS/Nova on 'Black Holes', a neat show, from of course, one of my favorites, Nova. Since per the Hawking idea that black holes will dissipate over a vast amount of time (trillions of years) means that as time goes on, stars go supernova per regular process, some turn into black holes. Others explode and scatter their elements to the universe and create more stars, etc.

In short, black holes are constantly being created but not destroyed on a 1-to-1 basis. Hence my conclusion that there are still lots of black holes out there, which is constantly growing. The only way we can detect a black hole is if there is raw materials being dumped into it, e.g., other close stars, other black holes, gas, etc. Otherwise, we would never know that a black hole is there, unless we purely by chance look in a direction and see a distortion (black hole wrapping space/light around it and we see from afar).
----------------------------------------------

How is the relationship between the expansion of the universe and the creation of black holes determined? How does that relationship interact?

I don't know, but would love to know if possible. What other mechanism already existing, cause the speeding up and expansion of the universe? Kind of like an 'expanding shockwave', where it gets greater and greater as it goes along.
----------------------------------------

We don't know the nature of Dark Energy or Dark Matter but we know they exist. Isn't Dark Energy already known to have an influence on the universe's expansion?

I've heard that it has a role in formation of galaxies and their shapes (their spiral shapes in particular), I didn't know about the universe's expansion being powered by dark energy, and would not surprise me, being that dark energy / dark matter makes up a major part of the cosmos.
-----------------------------------------

We're not really sure what happens on the other side of an event horizon. Even the most ardent astrophysicists will acknowledge that they only have educated theories about the physics inside a black hole.

I agree!
------------------------------------------
The 26 dimensions referenced:

Yes, string theory. And yes, there are 3 competing theories out there (to your statement that there is still an awful lot about these competing theories in question).
-------------------------------------------
Perceive even a fourth dimension.

I have no idea how it would influence my proposal, nor I would know how you would even prove it, if even you could, given all of the money and technology that would do it (if possible).
--------------------------------------------
Fascinating, isn't it? The other side of a black hole is as unknown as anything in this universe could ever be. Portals? A self-regenerating mechanism put in place by physics that we don't understand? They do say the physics as we know it break down, so you are right, there is a different set of physics perhaps. Who knows?


We're lucky to live in the time we do! You are absolutely right about this, a 100%!! A fascinating topic, wish we could find out more! Take care!
