Cosmology Update #4: New Heavenly Bodies

 
And I Thought Those Way-too-Early 

Galaxies Were the Story...  HA!

So far, only SIX of these have been found. [1]

THE REAL STORY

So far, 341"Little red dots" have been found by the mighty JWST space telescope. [2]

The best hypothesis about these (so far) is that they are Black Hole Stars, a completely new kind of celestial body! (The last such newbie is from 1992, the magnetar.)

I'm BIG, say 260 light years across. Think about it.

NOT SUCH A "LITTLE" RED DOT

These things -- astronomers are calling them "rubies" -- are beyond huge for something called a 'star."  If one was in the milky way, say 1000 light years from us, It would look gigantic -- biggest thing in the sky by a lot, nearly 30 times the diameter of the moon! Almost as big as the Orion constellation. As in huge. 

My Hypothesis Still Works!  (Cheering is heard off camera.)  In a nutshell:

Scooter Duff's  (updated) Theory of Cosmology

1. Dark matter was a first product of the Big Bang.  There was a LOT of it produced in the first nano-seconds of the BB. 

2.Since it interacts only gravitationally, it immediately started coalescing into fast growing lumps, then collapsing into black holes sucking ever more dark matter into themselves. 

3.At the time the rapidly expanding universe started "recombining" into atoms of hydrogen and helium  those gasses were grabbed by the nearest black hole to swirl around in ever-huger (!) amounts, becoming black-hole stars glowing brilliantly from the violent radiations and gravity surges from their central black holes -- now millions of times more massive than our sun. 

4. By ~500 million years after the Big Bang, some of these Red Dots (6 out of 341 more or less) converted the swirling gasses into actual, ordinary (baryonic) stars, and Bingo! those first galaxies came to be. 

5. As time progressed most, if not all, of the "Rubies" evolved into galaxies of various sizes.

6. And now here we are.

THE BOTTOM LINE IS THE SAME. 

SMBHs (supper massive black holes - like in the center of almost all galaxies) are... MOSTLY DARK MATTER! Sure, they've sucked in a lot of ordinary baryonic matter into themselves over time, but compared to the dark matter, not all that much.
