Finnegans Wake page 4: "Arms apeal with larms, appalling."

Explanation: Better known as M106, bright spiral galaxy NGC 4258 is about 30 thousand light years across and 21 million light years away toward the northern constellation Canes Venatici. The yellow and red hues in this composite image show the galaxy's sweeping spiral arms as seen in visible and infrared light. But x-ray and radio data (blue and purple) reveal two extra spiral arms -- arms that don't align with the more familiar tracers of stars, gas, and dust. In fact, an analysis of the x-ray and radio data suggests that the anamolous arms are composed of material heated by shock waves. Detected at radio wavelengths, powerful jets originating in the galaxy's core likely drive the shocks into the disk of NGC 4258.

Code: Select all

----------------------------------------
M106 is located about 7.3 Mpc away.

Hubble expansion constant ~ 74.2 (km/s)/Mpc.

M106 Hubble expansion  ~ 542 km/s

M106 is observed to be receeding at 448 ± 3 km/s

This APOD is inspirational. A beautiful island universe galaxy with a suspected huge Black Hole at it's center has inspired these questions:
1. Is it possible that Black Holes in galaxies will eventually start eating themselves up and eventually become so big that they will influence Black Holes in other galaxies with the result being all galaxies and interstellar matter will become one huge universal Black Hole??
2. Could a Colossal exploding Black hole been responsible for the origin of the suspected Big Bang and the birth of our universe??
Inquiring minds want to know!!!
Thanks for the opportunity to express a little white noise.

question 1. Is it possible that Black Holes in galaxies will eventually start eating themselves up and eventually become so big that they will influence Black Holes in other galaxies with the result being all galaxies and interstellar matter will become one huge universal Black Hole??

For something to fall into a black hole it must start out with
extremely little angular momentum vis-a-vis the black hole.

This restriction basically limits black hole fodder to:

1) original very local material or
2) occasional extragalactic material on extremely unfortunate trajectories
3) or occasional actors in an extremely bad Disney movie:

• ----------------------------------
  The Black Hole (1979)
  
  <<For five years the crew of the PALOMINO has ranged through deep space, searching for evidence of alien life--with no result. Then, their mission almost at an end, they discover a giant collapsar--the largest black hole ever encountered--and, drifting perilously near it, is the long-lost legendary starship CYGNUS...Incredibly, the ship is not a lifeless hulk. Its commander--the genius who designed the CYGNUS and planned its epic voyage--still survives, served by a horde of mechanical slaves. But Commander Hans Reinhardt (Maximilian Schell) has no desire to be rescued. He has a rendezvous with the incredibly hellish forces of the collapsar--and he plans to take the PALOMINO'S crew along on his doomed adventure.>>
  ----------------------------------
  Dan Holland: The controls aren't responding.
  
  V.I.N.CENT: Captain - the ship has been programmed!
  
  Dan Holland: [Resigned] To Reinhardt's course!
  
  Lieutenant Charles Pizer: [Shocked] You mean we're going into the black hole?
  
  Dan Holland: Looks like it.
  
  Kate McCrae: Let's pray he was a genius!
  ..................................................
  Durant (Anthony Perkins): There's an entirely different universe beyond that black hole. A point where time and space as we know it no longer exists. We will be the first to see it, to explore it, to experience it!
  --------------------------------------------------

questions 2. Could a Colossal exploding Black hole been responsible for the origin of the suspected Big Bang and the birth of our universe??

We are not allowed to discuss Cosmogony here.

[The Code]

After recent discoveries these questions might need to be answered? I found this:

http://www.dailygalaxy.com/my_weblog/20 ... -suns.html

Internal combustion engine.. Not all the fuel is burned after each explosion.

Dynamite is also not all used.

Super nova Gas left over

Singularity nova (Hypothetical) Not all the singularity is used.. some left over to form Black holes????

Just a thought.. How does a black hole become 18 billion solar masses? I,m Lost for Words : http://www.dailygalaxy.com/my_weblog/20 ... -suns.html

Could somebody move this thread so it can be talked about?? Please.

There is an interesting comparison that could be made between this image and (excepting the relative distances) our own orientation to Andromeda. To me, this looks like it could be an image of the MW (on the right) and Andromeda, M31 (on the left) with little M32 above.

Well, galaxies tend to exist in small clusters (ours is no exception). So it doesn't seem too surprising to find similar structures elsewhere. I agree that the image does seem to show something similar in structure and scale to our own local group.

What if the 'Big Bang' was really an 'anti Bang' and we are all anti what we would have been had the bang been a real bang?
If so, there is an earth on which dwells peace and harmony.

there is probably someone in the anti universe wishing the same thing.
there might be someone looking at our earth and thinking what they wouldn't give to live here. There might even be a signal sent to us from some distant world which we will never get for another 30 million years.

there might have already been 100 different civilizations to have lived in this galaxy millions or billions of years before we came along, let alone the entire universe. and each time one comes along, its a new chance for life to thrive and prosper. its a new chance for life to expand outside the world in which it is born, a new chance to take advantage of the vastness and richness of this universe, the NOW universe, our universe.

Hello Loco,

You seem familiar somehow...............could it be...............naahh.
