This won't work, you know. I have already moved on.
However, dark matter: Who knows? I don't.
OH GROSS!!!
I have just worked out what you meant by your mother's cherry red lips.
And all I have to say on the matter - apart from yuuuuuuuck! - is that if they really are that colour she needs to get seen to, 'cos that ain't right.
You are a bad, bad boy Malcom Crisp!!!!!

it's a cludge.
[a cludge is whatever you have to add (or subtract or multiply) to the answer the computer gives you to get the right answer]
Red shift observations (interpreted since the 50's as an expanding universe) indicate the "expansion of the universe" is speeding up. Contemporary theory could not account for it. So dark energy (which has a repulsive force opposite to gravity) was invented to "explain" it. Likewise, the outer edges of galaxies rotate too fast for the gravity produced by the visible stars to account for. They rotate more like solid disks. So dark matter was invented to explain it. It's a lot like humours and demons and spirits before the discovery of bacteria and viruses and brain chemistry.

Basically, astronomers reckon that there should be an awful lot more stuff in the universe than the glowing stuff (ie. stars) we can see. Even allowing for things like planets and interstellar dust, etc., there is still a BIG shortfall.
Think of the universe as a room. What comprises the greatest mass of stuff in the room? The air, of course, even though you can't see it. However, to an observational astronomist it would have to be the lightbulb, because it is the only thing giving off light.

darkish potential permeates the universe like gravity does, in truth it will be seen as anti-gravity. after we are saying what makes up the "majority" of the universe, besides the undeniable fact that, we mean the mass, the burden of all the stuff contained in the universe. This contains all baryonic count number and darkish count number. We infer that darkish count number has a wide quantity of mass by ways it gravitationally impacts galactic rotation and perhaps galactic formation.

The opposite of light matter. In plain language:
That means that roughly everything in the universe being light (stars) is held together by its opposite the dark matter.
I believe that there is no white without black, the duality.

We can't find it
Seriously, that's 4 words, and we can't find it. But it is a theory used to explain why there seems to be mass in the universe to make it work the way it does, that we can't quite find.

Invisible matter
two words!
Its basically matter that does not give off light like stars or radiate light like planets and dust. There should be lots of it but we cant see it and so we dont really know what it is either

Matter in the universe, detected only by it's gravitational force.

Unseen, makes up most matter in the universe.
Okay not exactly four words, but close.
I tutored astrophysics at uni between graduate degrees. I hope this suffices.
