	What is a Strangelet?
		Strangelets are theorized cosmological objects composed of an exotic form of matter known as strange matter or quark matter.
		Since strangelets maintain such deep gravity wells for objects of their size, calculations show that strangelets coming in contact with ordinary matter would overwhelm this matter with their gravitational fields, breaking down the ordinary matter into strange matter.
		If strangelets exist and keep coming into contact with ordinary matter indefinitely, it may be only a matter of time (albeit a cosmologically long duration of time) before strangelets swallow all the conventional matter in the universe.

	Strange matter - Wikipedia, the free encyclopedia
		There is some concern that ordinary matter, upon contacting a strangelet, would be compressed into additional strange matter by its gravity; strangelets would therefore be able to "eat" any ordinary matter they came into contact with, such as planets or stars.
		Strangelets are thought to have a net positive charge, which is neutralized by the presence of degenerate electrons extending slightly beyond the edge of the strangelet, a kind of electron "atmosphere." If a normal matter atomic nucleus encounters a strangelet, it will approach until it begins penetrating this negatively charged atmosphere.
		Sufficiently energetic nuclei, or neutrons (which are unaffected by electrical charges), can reach the strangelet and be absorbed; the up/down/strange quark ratio would then readjust by beta decay.

	Interaction of strangelets with normal matter
		Although the charge per baryon of a strangelet is small, it is sufficient to produce a coulomb barrier high enough to prevent such reactions at low energies.
		Strangelets would be inert in contact with ordinary nuclear matter in the same way that nuclei lighter than iron do not spontaneously undergo nuclear reactions.
		These are properties which would be studied once the strangelets were produced, but due to their uncertainty could not be used to identify strangelet candidates.

		Strangelets - sometimes also called strange-quark nuggets - are predicted to have many unusual properties, including a density about ten million million times greater than lead.
		While their very high speed gives strangelets a huge amount of energy their tiny size suggests that any effects might be extremely localised, and there is unlikely to be a blast big enough to have widespread effects on the surface.
		The good news is that, despite their force, the impact of strangelets on an inhabited area would, probably, be less violent than that of a meteor.

		A stable strangelet, if it formed, would almost certainly have a positive charge and therefore would be unable to interact with the positively charged nuclei of ordinary atoms, according to Madsen.
		There also are constraints, such as surface effects governing the shape of the strangelet, that would tend to limit its size and cause it to shed negatively charged strange quarks.
		The appearance of a strangelet would be the equivalent of an ice cube forming spontaneously inside a furnace, the panel said.

		The "killer strangelet" debate was sparked two years ago by an American theoretical physicist, Frank Wilczek, of the Institute for Advanced Study at Princeton University.
		Wilczek hypothesised that the pressurised superheat of collision could forge a "strangelet," an entirely new particle that would be a mix of stranges and other quarks.
		When this type of strangelet bumped into a nucleus of ordinary matter, it would "eat" it by binding the nucleus to the strangelet.

		A strangelet, if i have done my homework right, is a mathematical expression of an unprovable phenomenon whereby electrons have been theorised to jump backwards in time as they switch orbits around their atom.
		Strangelet can beat you up in chatrooms, Strangelet can whup your ass at Unreal Tournament, and Strangelet is cannonfodder in myth 2.
		Strangelet spends the rest of his miserable existence producing other people's music - he likes this as it removes the necessity for hard work.

		There is one physics scenario which would predict that all the strangelets made at the AGS would undergo ``weak neutron'' decay (decay via the weak interaction into a neutron and a baryonic remnant which would in turn decay, etc.).
		This is the model in which a strangelet production occurs via a QGP and the QGP undergoes ``strangeness distillation'' and produces a strangeness rich strangelet remnant.
		As soon as a strangelet charge is reached in the hadronization of the QGP for which the strangelet is stable under the strong interaction, the distillation ends.

	Wired 8.05: Dr. Strangelet or: How I Learned to Stop Worrying and Love the Big Bang
		In the collider's high-pressure, high-energy conditions, the quarks and gluons form a plasma, known as QGP, believed to have existed at the birth of the universe.
		A negatively charged strangelet would trigger a relentless process of electron-positron pair creation.
		The strangelet would strip away the electrons of any normal atom it came in contact with and absorb the exposed nucleus.

		Strangelets are chunks of matter made from "strange" quarks as well as the usual "up" and "down" types of ordinary matter.
		The risk is that a strangelet might consume nuclei of ordinary matter and convert them into more strange matter, transmuting the entire Earth into a strange-matter planet.
		"Strangelets are almost certainly not stable, and if they are, they almost certainly cannot be produced at RHIC," he says.

	[No title]
		In view of the high cost of a strangelet disaster (total destruction of the Earth and all its life), it is inappropriate to consciously overlook any worst case in computing a probability of disaster.
		Assertion 3 There must be a continuous line (in the mass-charge space) of stability for negative strangelets (assuming positive strangelets are benign) for them to be dangerous (and it is sufficiently unlikely that such a line of stability should exist).
		Using a strangelet of half that mass results in a much larger computed probability of 10-23, which over the lifetime of the RHIC gives a probability of 10-12, several orders of magnitude greater that the desired safety limit of 10-18.

	The Strange Matter of Planetary Destruction
		The first is that the only kind of strangelet that could fuse with ordinary matter would be a negatively charged strangelet and that they are very unlikely to be produced.
		That's enough time for the strangelet to traverse the vacuum in the RHIC, penetrate the iron wall (being slowed to thermal velocity in the process) and mingle with the helium atoms in the super-conducting magnet cooling jacket.
		If the strangelets are stable, (long-lived) they could be swept up in the course of years in new star development.

	The results
		This behavior is one of the primary concepts in understanding the phenomenology of strangelets.
		This is because electrons are not present in strangelets; if they are included, consistency is restored.
		Although this is much to simple a picture to determine the percentage of electrons near the core of the strangelet, it is clear that the transition to bulk strange matter is near.

		But his strangelet scenario deserves special consideration here at Harvard because particle accelerators figure prominently in the work of several of the University’s most prominent physicists.
		According to Posner, an upper-bound estimate of the danger of a strangelet disaster is 1 in 500,000 over the 10-year period for which RHIC will be in operation.
		Posner takes a midpoint between the two disaster estimates, and he posits—for the sake of argument—that the likelihood of a world-ending strangelet scenario over the next decade is 1 in 10 million.

		Strangelets are thought to have a net positive charge, which is neutralized by the presence of degenerate electrons extending slightly beyond the edge of the strangelet, a kind of electron "atmosphere."
		If a normal matter atomic nucleus encounters a strangelet, it will approach until it begins penetrating this negatively charged atmosphere.
		Strange matter is largely theoretical at this point, but observations released by the Chandra X-Ray Observatory on April 10 2002 detected two candidate strange stars, designated RXJ1856 and 3C58, which had previously been thought to be neutron stars.

		Unlike a proton or a neutron, which consists of three quarks, a strangelet would have at least six.
		But it could have more, so the fear was that if a strangelet united with a normal atomic nucleus, it would cannibalise it to form a larger strangelet.
		His maths show that strangelets will be positively charged—a fact previously unknown, despite all the theory that seems to have been developed about them—and will thus repel normal atomic nuclei, which are also positively charged.

		A strangelet could be detectable in a particle spectrometer such as AMS-02, and indeed one event compatible with the strangelet hypothesis was observed by AMS-01 during the successful 1998 STS91 mission.
		A strangelet would, however, also have a peculiar interaction with the Earth, giving rise to a unique pattern of "epilinear" seismic signals that would indicate a linear source.
		Such events have been searched for: in more than a million seismic events recorded in the years 1990-1993, one puzzling event that could be compatible with the passage of a strange-matter nugget through the Earth has been found.

		Use the RHIC to create and maintain a stable strangelet.
		Keeping the strangelet stable is incredibly difficult once it has absorbed the stabilizing machinery, but creative solutions may be possible.
		A while back, there was some media hoo-hah about the possibility of this actually happening at the RHIC, but in actuality the chances of a stable strangelet forming are pretty much zero.

	Strangelets - Strange Quark Matter
		Strange quark matter (SQM) or strangelets are strange clusters containing a large number of delocalized quarks
		Droplets of SQM, which would contain approximately the same amount of u-, d- and s-quarks (strangelets, strange multiquark clusters), might also be denser than ordinary nuclei.
		The (weak) decay of a s-quark into a d-quark could be suppressed or forbidden because the lowest single particle states are occupied (Pauliblocking, analogous to the MEMO case discussed above).

		It aims to produce energy densities sufficient to produce a new phase of hadronic matter -- a Quark-Gluon Plasma.
		It may be that the inclusion of strange quarks (a strangelet) could achieve a lower energy state by reducing the Fermi energy.
		This led to a possible doomsday scenario, in which a negatively charged glob of strange quark matter might start to accrete normal nuclei, and in principle swallow up the Earth.

	Bird's Eye View: Stranger than a strangelet
		What I find amusing is the conceit that religion deals with bizarre ideas divorced from real experience and science deals only with harsh reality.
		In fact the reality that science is uncovering is both strange and wonderful, and we can know it only through indirect effects and metaphorical imagery (is a strangelet really a "nugget"?) I understand quarks in much the same way as I understand God.

		For example, “strangelets” composed of quark matter could be traveling in our vicinity at speeds of 900,000 miles per hour.
		The density of such a strangelet would be 10 million million times that of lead.
		Scientists have found that our planet has experienced cyclic episodes of bombardment and extinction at regular intervals during the past 100 million years—specifically 94.5 million years ago, 65 million years ago (the event causing the extinction of the dinosaurs and many other species), and 36.9 million years ago.

		The names physicists have given this type of matter are "quark matter" or "strange matter".
		This may be regarded as a phase change, like changing from a liquid to a solid, only at densities many orders of magnitude greater than those occuring in this solar system.It has been hypothesized that strangelets (sub-stellar agglomerations of strange matter) may be able to exist independently from the quark stars which created them.
