What the quark?! Why matter's most basic building blocks may not exist
-
Quarks are the subatomic particles thought to make up
nearly everything we can see.
Now it turns out they could be an illusion created by quantum trickery

In modern physics, a quark is what you would find if you were
able to take a piece of matter and cut it in half again and again
until you could cut no more.

Quarks are as fundamental as anything can be.
But they are also exceedingly weird.
They have strange quantum properties known as flavour and spin.
They crave each other’s company, clustering together in pairs
or triplets. And they have a special sort of charge that comes
not in the positive or negative variety, but in colours.

And now, in a twist to rival that of any experimental novel,
it seems quarks may not actually exist.
According to tantalising new research, they may instead be
an illusion, the product of quantum trickery we don’t yet
fully understand. Perhaps the …

Quarks are very different from other particles in that they
have an electric charge that is 1/3 or 2/3 that of the electron and proton.

They also possess a different kind of “charge” known as color.
Just as electric charges interact through an electromagnetic force,
color charges interact through the strong nuclear force.

It is the color charge of quarks that works to hold the nuclei
of atoms together. Color charge is much more complex than
electric charge.

With electric charge there is simply positive (+) and its opposite,
negative (-).

With color, there are three types (red, green, and blue) and
their opposites (anti-red, anti-green, and anti-blue).

Because of the way the strong force works,
we can never observe a free quark.

About a Quark Star
#
There has been some experimental hints of tetraquarks,
. . .
This means that quarks can combine in much more complex
ways than we originally expected, and this has implications
for the internal structure of neutron stars.
. . .
Very simply, . . .
With the existence of tetraquarks, it is possible for neutrons
within the core to interact strongly enough to create tetraquarks.
This could even lead to the production of pentaquarks
and hexaquarks,
or even that quarks could interact individually
without being bound into color neutral
particles.
This would produce a hypothetical object known as a quark star.
