How likely is it that globular clusters are juvenile galaxies?
Probably unlikely, in this model the compressed matter in the spiral arms expands in emission nebulae, to form stars and globular clusters that drift to stations above and below the disc, as the spiral evolves into an ellipse. The globular clusters form a placenta, that effectively shields the galaxy from radiation, and a buffer zone against collisions and impacts with other galaxies.
So galaxies calve?
Sure they do, look for rare shots of spidery looking juvenile galaxies drifting away from parent bodies!
The above pic is galaxy M31 the closest major galaxy in the constellation Andromeda, not counting Dwingeloo 1 a much closer galaxy that has been radio located directly opposite the nucleus of the MW, thus it remains invisible from Earth, the fuzzy blob below right center of M31 is satellite galaxy M 32, the large blob in the disc slightly below left center is M 110, both could be embryo galaxies that will expand as a child galaxies of M31!
Omega Centauri called NGC 5694 is an embryo galaxy of the Milky Way, it has no active nucleus so it is unlikely to change, it could start spinning and flatten into a disc, then might drift away as a low surface brightness galaxy.
LSB galaxies are very numerous and collisions between them are frequent, they do not show up at all on most conventional photo’s, their presence was only revealed after large numbers of blue arcs centered on super massive elliptical galaxies, turned up on deep field shots, so astronomers started looking for more and found millions, near and far.
During this collision phase if two colliding members are compatible, they combine then rapidly evolve into an active disc as the nascent black holes lurking at the heart of both respond, then reproduce.
What happens next?
The active nucleus of spiral galaxies like the MW and M31, expand and gather all the dust and debris in the galaxy then contract into a very dense center, the material goes into the torus, the donut of swirling dust and shattered stars that insulates the central surrounds of the black hole, or cluster of BH’s at the center of the galaxy.
Centaurus A an exploding galaxy in that constellation, thought to be about twenty six million light years distant, appears to be presently undergoing that process.
Astrometry data is essential, so has it been hijacked by NASA and JPL, whose joint purpose has itself been hijacked by defense, which has been hijacked by hijackers who run government, who employ hijackers to hijack hard evidence and true science.
They try to sell their version back to the public in books and publications, with Saganesque data about cannibal galaxies, and wanna tell you, “…well there was this Big Bang,” there was no BB, man is gonna plunge back into the age of ignorance, while it remains the province of the select few, with the right security clearance, to get an education.
Check the shot of Sagittraius A* above, there is a distance bar, but no image width scale without which it remains a pretty picture with absolutely no scientific value whatever!!
With good sky maps available, that have photographs and catalogs of deep fields, and astrometry, radio locating and red shift data, it does not take long to figure it all out, the data that is released is most often too raw, with dazzling columns of figures and seemingly contradictory terms, it is seldom in a form that can be used for home astrometry, the photographs and charts they reproduce never have grid markers, so scale always remains a mystery.
This thread commenced at NGC 253, and was intended to refute the claim that the universe is expanding after the explosion of a primal atom, evidenced by Redshift which Big Bangers say shows the velocity of physical recession, which true science recognizes as an artifact of distance.
Nowhere do distant galaxies show evidence that they are fall out from an explosion, there is no trail of smoking debris like there was at the WTC on 911, which was from a genuine big bang, nor do they appear to be doing anything except drifting about a bit, until they establish stable orbits with other members in their group.
