>Chemical elements constitute all of the ordinary matter of the universe. However astronomical observations suggest that ordinary observable matter makes up only about 15% of the matter in the universe: the remainder is dark matter; the composition of this is unknown, but it is not composed of chemical elements.

How can this be possible? Does dark matter not have atoms or quantums??

It doesn't have atoms, but it is probably just a new type of particle i.e the quantum of some field.
Also, the plural of quantum is quanta.

oh yeah, and to answer the question itself; There are things besides electrons and nucleons out there. Neutrinos only interact via weak and gravitational interactions IIRC.

>>10503728
so if we discover what dark matter is made of it doesn't go on the periodic table?

There's some kind of matter in the world that doesn't interact with anything except gravity and only has mass. No electrical charge.

You can't "see" it but you can see that galaxies, for example, are heavier than all the stuff we can see. Five times heavier.

No. The periodic table tells us what atoms we can find out there, but atoms are made up from constituent parts like electrons and the nucleons. Dark matter wouldn't be either of those things so won't form atoms as we know them. Despite all the evidence we see of its gravitational effects and some predictions for what it might be we're still waiting for a conclusively detection telling us anything about its specific nature.

so you mean the super black holes, are they made out of dark matter or chemicals? Is there dark matter on earth or in our bodies but we don't know it?

The other anon didnt mean black holes when he said dark matter. Black holes can be "seen". They "emit" Xrays that can be detected and other things like motion around other celestial bodies. Dark matter and dark energy arise huge and undismissable discrepancies in mass and energy calculations, for which we cant account for since we literally dont "see" them with all our machines and mathematical tools. So much was the desperation to understand the discrepancy that we gave them a name yet we dont understand them at all, for now.

what chemical is a black hole made out of then

>>10503854
why are you so obsessed with chemicals.

[Anonymous No.10503884]

>>10503854
It is'nt a chemical. A chemical means something we deal with almost on a daily basis and something that can show its atomic composition with a spectrograph analysis (one of the many tools we use to determine what distant shit is made of). Dark matter is a predicted entity which has not been understood yet, on all levels except that we know something is there. Also now I realize it was bait all along. Thanks for wasting everyone's time.

not any chemical for sure, but the truth is we don't know. It's probably more like "dark matter"(if it exists) than it is like the particles that we know of.

Dark Matter is a dimensional scaffold for matter existing within our three dimensions of space and time. Dark Matter should correctly be called Dark Mass, Dark Mass has no matter of its own and can only be detected by its gravitational effects.
On the other hand we have Dark Energy, which correctly should be changed to Dark Energetic Information which gives each scaffold it`s own unique shape or properties. It's detection is what we see in this universe.
