Perseus Cluster Core

Post by wainwril » Fri Dec 09, 2005 7:55 pm

Even with the great expanses of our universe, isn't it practical and even probable that super giant black holes might come into existence due to available material like the Perseus Cluster Core? Might this evolution be on a non-linear scale, i.e. speeds up towards the end as super giant black holes become Mega Giant black holes and therefore change gravitational constants? Should all available material come to one point, couldn't that explain the "Big Bang" theory and essentially repeat it? Does God Recycle?

Recycling of matter

This is a perfect example of matter been recycled on a grand scale

Exaplains the
Hubble Finds More Evidence of Galactic Cannibalism

--------------------------------------------------------------------------------

Full press release text:

Hubble's superb resolution has enabled the identification of a class of small and very faint star clusters in the central region of NGC 1316, a giant elliptical galaxy in the southern constellation Fornax. Many of these clusters are so small that they are barely held together by the mutual gravity of their constituent stars.

Though such clusters are common in spiral galaxies like our Milky Way, they have rarely been seen in elliptical galaxies. The astronomers conclude that these clusters are among the last visible remains of a galaxy which was cannibalized by NGC 1316.

That NGC 1316 has swallowed whole galaxies is evident in the wispy, smoke-like tendrils of dust, which are believed to be the remains of a gas-rich galaxy that collided and merged with NGC 1316 sometime during the last hundred million years. Other signs of a violent past include arcs and plumes of stars emanating from the outskirts of the galaxy.

NGC 1316 is a tremendously powerful source of radio waves, which are thought to be generated by a massive black hole at the galaxy's center. The gaseous remains of the cannibalized galaxy are falling towards the center of NGC 1316, where they may ultimately end up feeding the black hole and providing the energy needed to sustain enormously energetic jets of material which extend outwards for more than 250,000 light-years.
-------------------------------------------------------------------------------------

In the last few years through the aid of the hubble telescope we are finding more eveidence of the endless process of recycling.

Our local cluster of about 35 galaxies has M87 as its central galaxy. M87 houses a Black Hole several light months in width and has an active process of ejecting matter back into space.

Yes, a very pretty picture. :D
