Black Hole Universe Cosmology

[mibn2cweus]

I'm initiating this thread for any who might share my interest in and/or care to discuss 'black hole universe cosmology'.

For some background on this theory here's a link to a relevant paper I've found that proposes this idea - http://www.ptep-online.com/index_files/2009/PP-18-01.PDF.

I'd like to stress that this thread is open to any and all for discussion of this or any related topics.

//I referred to galactic voids in the other recent thread - what if they contained galaxies made inconspicuous in such a way (not so many as to block our line of sight to the more distant side of the void and the galaxies beyond it)?//

One way that the presence of a black hole is made evident is by the apparent bending of light from galaxies or other bright light sources that happen to be in line with and nearly directly behind them. As far as I know, all black holes that have displayed this phenomenon reside within galaxies of their own.

I still get emails from (crowd sourcing website) galaxyzoo.org and they were running a gravitational lens project, a few years ago. I only spent over an hour, giving it a go but I didn't set eyes on a single pic which wasn't marked as having been viewed before, most had been assessed tens or hundreds of times. Therefore, I didn't get 'hooked' into becoming a regular visitor. It did broaden my horizons as to the sheer quantity and variety of deep sky objects there are out there. Hubble was worth every cent, imho.

It won't account for the famously missing mass but I do wonder how
many super-distant galaxies are literally hidden from our line of sight behind foreground galaxies or even stars (hopefully they don't obscure much once they are beyond parallax range).

Thanks for your 22:06 explanation too. I hope my post wasn't too obviously set up to invite that. And I'd completely overlooked the issue of galactic core black holes.

Read the link, too. Two unexpanded acronyms (GMR/CMV), one unrecogniseable character (inverted V, not a capital delta, I thought), one unrecognised mathematical symbol. The usual stuff to keep casual speculators, like me, off the grass. (No maths A level. Silly me!)

Sad problem hypo is that to answer the question properly you basically have to rely on mathematics. There's very little that just talking about the idea will accomplish unless yo can start making predictions and testing or disproving them.

I scanned the link of mib's and it seems to be arguing that the numbers just aren't compatible actually, but I would have to check them myself before agreeing or not. I would be surprised if the numbers were compatible with the idea that we are inside an ultramassive black hole, but numbers can surprise you sometimes so if I do get a chance (very unlikely, sadly) I will try and check.

I couldn't find either of the abbreviations you mean, but the symbol that's an inverted V is a capital greek letter Lambda, and stands for the cosmological constant. the ΛCDM abbreviation stands for "Cold Dark Matter with a cosmological constant" and is basically the currently accepted model for big bang cosmology (the word "cold" in this context means, essentially, moving only very slowly). GTR just stands for "General Theory of Relativity".

If there's anything else I can help with let me know and I'll have a go trying to explain further. These things are complex and I'm not convinced I'll be able to explain them very well as, like I hinted earlier, General Relativity is not really something I know beyond a basic undergraduate level.
