BARYONS: family of sub-atomic particles referring to tri-quarks that is it is made up of three quarks. Their baryon number is 1. Each baryon has an antiparticle in which quark is replaced by corresponding antiquarks Examples:- lambda, sigma ,proton, neutron, xi, omega They can also be defined as strongly interacting fermions.

∙ 8y ago"Baryonic matter" is basically a fancy way of saying "normal" matter, as opposed to dark matter. The most common baryons in the universe are protons and neutrons, which make up normal everyday atoms.

What is a baryon acoustic oscillation?
A baryon acoustic oscillation is one of the regular periodic fluctuations in the density of the visible baryonic matter of the universe.
How much of the universe is considered to be plasma?
Plasma is a state of matter. Unfortunately, only 5% of the universe is actually made of matter. The rest is dark energy and dark matter: poorly understood forces.However, virtually all of that 5% is plasma! Most of the matter in the universe is part of stars, or has been ejected from stars. Stars are composed almost entirely of ionised gasses: plasma! Planets, asteroids, comets and humans, and everything else that is not a star, makes up a tiny fraction, less than 0.01%, of all the matter in the universe.
Where could you find plasma the fourth state of matter?
Mainly in stars - thus, the plasma state is the most common state of matter in the Universe, at least when talking about baryonic (i.e., "normal") matter.Also, under laboratory conditions it's possible to heat matter to the point of becoming a plasma.
Does the amount of weed consumption matter?
Yes. Matter to what? Yes. Matter to what? Yes. Matter to what?
Is radio waves matter or non-matter?
No, radio waves are not matter.
What does 'non baryonic' mean?
Non-baryonic refers to particles that are not made of baryons, such as protons and neutrons. Examples of non-baryonic particles include neutrinos, dark matter, and photons. Non-baryonic matter plays a crucial role in modern physics theories, such as explaining the missing mass in the universe.
What state is not matter?
Plasma is probably the answer you're looking for, although it is still baryonic matter, but it is not like the usual matter found on Earth.
What are some sources for baryonic dark matter?
I presume you mean, "What might baryonic dark matter consist of?" It MIGHT be non-luminous gas, MACHOs (a cute acronym), condensed matter like black holes & white dwarfs, and brown dwarfs. The measured ratio of hydrogen to deuterium to helium in our Universe precludes the possibility that a large proportion of dark matter could be baryonic. The proportion could even be negligible.
What is the percentage of aluminum the universe?
Of all the baryonic matter, aluminium makes up about 0.005%. Considering that ordinary baryonic matter makes up about 4.9% of the universe, that would make aluminium constitute about 0.049 x 0.00005 = 0.000000245% of the mass of the universe.
What are the estimated total amounts of baryonic matter in the universe?
About 4% of the matter in the Universe is estimated to be baryonic matter. In absolute terms, it is hard to say, since we don't know how big the Universe is. Such estimates would therefore have to be done in terms of the "observable Universe". Here are some estimates: http://en.wikipedia.org/wiki/Observable_Universe#Mass
What kind of energy is matter?
The only kind of energy that dark matter is -- well, MATTER. Or mass, if you prefer, which is the same thing. We don't know what KIND of matter this stuff is, hence the name "dark." The only two things we know about dark matter is that (1) it interacts with baryonic matter via gravity but (2) it does NOT interact with baryonic matter via the electromagnetic force or the strong force. At this point, we're still working on what type of matter would do that.
What does measuring the amount of deuterium in the universe allow us to set a limit on?
The density of ordinary (baryonic) matter in the universe.
What is a BAO?
A BAO is a baryon acoustic oscillation - one of the periodic fluctuations in the density of the visible baryonic matter of the universe.
What is helium percent by volume?
Helium accounts for around 8% of the volume of all matter (baryonic particles) in the universe.
What percentage of thorium is in the universe?
Thorium constitutes about 4E-8% of the visible baryonic matter of the universe by mass. Visible baryonic matter is about 4.9% of the total mass of the universe, as per the latest estimates. So the mass-percentage of thorium in the universe would be 4E-8 x 0.049 = ... very little.
What makes up a universe?
About 68% is dark energy and 27% is dark matter. The remaining 5% is baryonic matter, which includes our Earth, the galaxies, and the contents of intergalactic space.
What is a baryon acoustic oscillation?
A baryon acoustic oscillation is one of the regular periodic fluctuations in the density of the visible baryonic matter of the universe.
