Not a Quirk But a Quark ... a Quark Star!

One was first observed using a robotic telescope at Caltech's Palomar Observatory. Data collected with Palomar's Samuel Oschin Telescope was transmitted from the remote mountain site in southern California to astronomers via the NSF-funded High-Performance Wireless Research and Education Network (HPWREN). The Nearby Supernova Factory research group at the Lawrence Berkeley Laboratory reported the co-discovery of the supernova, known as SN2005gj. Researchers in Canada have analyzed this, along with two other supernovae, and believe that they each may be the signature of the explosive conversion of a neutron star into a quark star.

Astronomers recently announced that they have found a novel explanation for a rare type of super-luminous stellar explosion that may have produced a new type of object known as a quark star.

Researchers in Canada have analyzed this, along with two other supernovae, and believe that they each may be the signature of the explosive conversion of a neutron star into a quark star.
These three supernovae, each 100 times brighter than a typical supernova, have been difficult to explain. The Canadian reserach team thinks the explosions herald the creation of a previously unobserved and new class of objects designated as quark stars.
A quark star is a hypothetical type of star composed of ultra dense quark matter. Quarks are the fundamental components of protons and neutrons, which make up the nucleus of atoms. The most dense objects known to exist today are neutron stars--stars composed entirely of tightly packed neutrons. A typical neutron star is some 16 miles across, yet has a mass one and a half times the mass of our Sun.
Neutron stars are formed when a massive star undergoes a supernova explosion at the end of its life. The question is, is a neutron star indeed the most dense object that exists? It is thought that if the neutrons are too tightly packed--if what scientists consider a neutron star is too dense--the resulting instability may lead to a further collapse, resulting in a second explosion and the creation of a quark star. The energy that powers that second explosiion comes from neutrons breaking down into their component parts: quarks.
Further observations should help to confirm or defeat the hypothesis of quark stars, but in either case, the use of a high-speed network like HPWREN helps astronomers across the world explore the frontiers of science.

Other than a "yummy new type of bomb", I can't see the motivation for this purely speculative physics. They are breaking much more than the laws of physics here, they may also be breaking the laws of morality as well. It will get funding for no other reason than it's hard to say "no" to even more powerful "explosives" than fusion devices. They are "pressing all the right buttons"... Unfortunately.
IMHO they should look for answers in other more plausible arenas.
True, but that's not what they're talking about. And I can see no reference to bombs here either. Keep your hat on please.

Here are some theories, the increased frequency of quark and strange matter stars would signalize the upcoming phase transition of vacuum into a new generation of Universe.
well.. quarks would still be confined within the star.
