If quark stars were to exist, would we expect them to demonstrate more extreme forms of the behaviours observed from neutron stars?
For example - would we expect quark stars to have intense magnetic fields in the same way neutron stars do, that could then lead to them becoming pulsars?
Or would the breakdown of hadrons into quark ...

If either existed, how would the process of a quark star transforming into a strange star alter the physical size of the object?
I'll admit this is actually several questions rolled into one...
1 - Assuming I understand the theory behind quark stars correctly, only a certain number of up and down quarks can occupy the same ...

Which features of the Morris-Thorne wormhole require exotic matter?
This particular solution has some features that make gives it more utility for humans, such as time stability, enough size for someone to transverse it and other things made for humans. Could an ...

Could there be states of matter that could avoid "matter decay"?
Regular structures of matter may decay over extremely long periods of time (especially if proton decay occurs, which is not proven but it remains a possibility)
Even if that happens, are there any ...

Are pure quark stars possible?
Has it been established that structures formed from quarks (like quark stars: https://en.wikipedia.org/wiki/Quark_star) are possible in principle ?
I have read about the possibility that inside ...

Stable/metastable nuclei with excited nucleon states
I was reading about nucleon excited states such as the delta, and saw a passing comment that some nuclei may have a delta or N particle in place of an ordinary nucleon, and that said nuclei were “...

Could the LHC create a strangelet by creating another multi-strange particle that then interacts with a nucleus?
I became interested in the discussions about potential catastrophic risk from colliders and I have some questions about it.
I am particularly interested in the strange matter scenario, and there is ...

What would happen if a multi-strange particle were absorbed by an atomic nucleus?
I have been reading about the hypothetical possibility of "strange matter consuming the Earth" and there is one thing I don't understand. I understand that it has been shown that it is ...

Is there a list anywhere of known or hypothetical hypernuclei?
Does anyone have resources that include a list or set of descriptions of hypernuclei that been observed, or been proven to be possible hypothetically? Is it possible, even, that there is something ...

Overview of quantum energy teleportation
I'm looking for a research-level review of the concept of quantum energy teleportation.
I did find http://www.tuhep.phys.tohoku.ac.jp/~hotta/extended-version-qet-review.pdf, but it is more than 10 ...

What are strange metals?
What are strange metals?
Are they something that we have really made, or just a theoretical idea?
If they have been prepared in laboratory, then what are their properties (or if they are still a ...

Why is most of the matter in the universe made of hydrogen instead of helium? Or iron?
Hydrogen, while being the simplest element, is near a peak of the binding potential curve. Presumably in the first 1 second or less of the Big Bang timeline, densities and temperatures were such to ...

Is it possible for there to exist metastable exotic atoms?
I've been quite fascinated with the invention and discovery of exotic atoms such as: positronium, and muonic hydrogen etc...
Now I know positronium has a longer than usual lifetime because it is in a ...

Mass curves spacetime. Is there any theorized "anti-mass" that counteracts this effect? [duplicate]
Things like faster-than-light travel have very good reasons for being believed theoretically impossible (e.g. they allow traveling backwards in time). Things like magnetic monopoles are seemingly ...

Violations of the Achronal averaged null energy condition
Many energy conditions have been shown to be violated in the past in semiclassical gravity, for instance when considering Klein-Gordon quantum scalar fields. Victims include the WEC (Weak Energy ...
