Quark stars are thought to exist. They are denser that neutron stars
but not quite black holes.

They are composed of what is called strange quark matter. If such a
form of matter can exist outside of these stars, it is thought it
could convert any ordinary matter it came into contact with into dense
strange quark matter!

can free quarks exist?
 

Guys,

Supposed (just an example) a single free quark exists and it
floats in mid air and I walk towards it.. Would it go pass
thru my body or would it stick to my shirt?

What part of the atoms gives matter its form. I mean, 99%
of the atom is empty. So I assume the free quark should
be able to pass thru me since it can pass in between the
atom, right? Or would it be magnetized to the nucleus?

Kyle

---------------------
there are rumours that quarks can bite and even kidnap little children1

some people say that during cold nights they could hear them
sing starange songs.
now more serriously:
if quarks exist, they are composed by the electron family particles.

Kyle is being silly. The penetration depth depends upon the quark's
kinetic energy. Quarks have electrical charge, and a moving charge
loses kinetic energy by ionizing the atoms of the material it passes
through. A slow quark wouldn't make it though your shirt, and a very
high energy quark would pass through your body, leaving an ionization
track along its path.

The most damage would be done by a quark that almost penetrated
your body before coming to rest. The energy loss per unit track
length, dE / dx, is proportional to (q / v)^2, where q is the electrical
charge on the quark and v is its speed. Since quark charge is less
than that of a proton, The range or stopping distance of a quark
would be greater than that of a proton of the same initial speed. Not
to worry. Your body is penetrated every few seconds by secondary
cosmic rays (mostly muons). [Old Man]

I guess in a quark star, lambdas take up less space than neutrons and
this pays for the extra mass, but is there a layman-accessible
explanation of how even in theory strange matter could be stable at
normal pressure? Or how it could convert normal matter into strange
matter? Where would the energy come from?

-------------------------
its the first time in my life that i agree with Bilge,
very nice Bilge
some wheels started to move different in your mind.
go on with it.
(of coase i guess you will not admitt it (:-))

yesterday i had some belly pain
may be because i ate earlier some quark soup
which contaied too much d quarks
and may be their surface tension was too high>

so may be gordeon D Pusch which is an expert for quark soup
can give me the right recepy of the right soup
so that i(and the other readers (:-) will not suffer too much
from indigetion
with not too much d or strange quarls and with less
'surface tension'
TIA

so who is the sucker who wants to 'eat' them?? (:-)
did intelligent people lost completely their crytisism sense
of their physical commonsense?1

to detect 'scintific' croocks?)

But isn't this only true because the pressure is so high, therefore
there's a strong incentive (if I may be forgiven the anthropomorphic
terminology) to pack the particles as tightly as possible (akin to the
reason degenerate matter over the Chandrasekhar limit turns into
neutronium)? Surely at normal pressure there would be no such
incentive?


I don't understand this - don't d and s quarks both have a charge of
-1/3?


But in normal matter, aren't the Fermi levels lowered simply by not
packing the particles so tightly?

Another thing I just thought of - if strange matter were more stable
than normal matter, since there were presumably lots of strange quarks
in the very early universe, shouldn't matter have stayed in that form?
