Re: New form of matter may lie just beyond the periodic table
#2I couldn't find anything on the expected half-life of udQM in the paper, just how stable are we talking here? The theoretical "island of stability" is only relatively stable (minutes to days) and useless for practical applications.

The article did say that udQM could come in via cosmic rays, this would have to be quite stable over the thousands of years it would take such rays to get to us.

So what is the QM that is found in colliders? “When produced in a collider, quark matter typically decays within a fraction of a second into stable hadronic matter (with bound quarks).” Obviously not udQM, right?

It could be non-stable udQM. Not all udQM is stable.

>SQM consists of comparable amounts of up, down, and strange quarks. One of the new results of the latest study is that quark matter without strange quarks, i.e., udQM, has lower bulk energy per baryon than either SQM or hadronic matter, making it energetically favorable.
I would guess QM composed of strange quarks in addition to up and down, and/or below the "continent of stability" size of 300 Angstroms[1].

#7... quark matter has the potential to be used as a new source of energy
A new kind of weapon? Renewing the nuclear arms race?

Who needs deadlier stuff than nukes? Let's root for Quark matter drives instead.

Not from the sounds of it.
It's pretty hard to beat existing nuclear weapons, honestly, and even if you could, existing nuclear weapons will be much cheaper for a long time. The bulk of them is already delivery mechanism rather than the warhead.

I thought that due to relativity, if the elements are travelling close to the speed of light then they could still travel for thousands of years even if their their half lives are much shorter. That's because the element only appears to be thousands of years old from our frame of reference; their age is much less when viewed from their own reference frame. Though given the size and mass of these elements that might be a moot point since it's unlikely they could be travelling at near light speed anyway, due to the enormous energy it would require for them to do so?
