what is the Ω‾ particle

These 2 questions are totally unrelated.

The electrons do not collapse onto the nucleus for two reasons   firstly because they can't  their light mass means that their quantum mechanical uncertainty of position and momentum prevents the from being located inside the nucleus all the time (although they do have a probability of being inside the nucleus.  next they are fermions and only two electrons of opposite spins can occupy the same quantum state so once there are two as close to the nucleus that they can get the rest have to make do with other quanum mechanical orbitals with higher energy.

The omega minus particle is one of a group of subatomic particles called baryons.  It is composed of three strange quarks.
more details are here  http://en.wikipedia.org/wiki/Omega_baryon  Its discovery helped to confirm a theory of the way subatomic particles made from quarks were formed and was essentially one of the first particles to be predicted by a model rather than discovered in high energy physics experiments.

Perhaps we should ask why they don't fly off at a tangent.

Are you trying to temp someone to use the "c" word so you can come down on them like a ton of bricks ?.

LOL! Nice one.

They don't circle. Electrons orbital, meaning that they become a probability function, a 'description' of a orbit, undefined until acted upon, as a measurement. That also seems to allow one electron to be at two 'places' simultaneously under some circumstances. What we can say with rather good assurance is that invariant mass, as rest mass (particles) take 'place' wherever they may be. Bosons don't, at least most of them. When using BEC:s (Bose Einstein Condensates) chilled down just above absolute zero some weird 'fermions' aka rest mass particles transition and get some of the properties of 'bosons' (helium4-3) similar to light. But as far as I know it's only 'real natural bosons' that we're supposed to be able to superimpose upon each other, all photons in this universe in one 'place', but not there at all, as they are 'point particles'. Defined as even when having a 'locus', as observed, still not taking any 'real place' at all. That's why we say that we can superimpose them on each other too.

Well clearly the centrifugal force holds them in place!

Oh yeah? You'll have to come up for air sooner or later, so expect a visit from my Rhode Island associates.

Isn't that a sauce?

Oh yes! Rhode Island salad dressing. One of the main ingredients is lead.

The problem is you are visualizing the Bohr model of the atom.  Electrons circling protons and nuetrons is easy to visualize, but it has nothing to do with reality.  The current theory of the atom is the "standard model" which is mearly a list of properties (mass, spin, and charge) none of which we have a clear understanding.  The answer to your question is, electrons don't collapse to the center because there is no such thing as electrons racing around a nucleus.
