Mass/Matter. Both “light” and dark.
Matter is the stuff we can see and/or measure in the universe.
Darkmatter is the word scientists use for all the stuff we can’t really account for or measure in space, but we still know that it must be there, and scarily it makes up about 85% of the stuff that is out there!
That’s probably not that helpful an answer because I can barely even wrap my head around what that really means – but it’s the only one I really have because it’s such a complex subject and very much not my field, though it is of interest to me! I’d suggest checking out some of the work Prof Brian Cox did for the BBC, I’m sure he touches on this topic a little bit there!

Well about 5% is made up of what we would call “Matter” which is atoms and it is what makes up everything we know. The other 95% is dark matter or other things we just do not understand. There is a lot of work going on to try and work out what it is.

The Universe is thought to consist of three types of substance: normal matter, ‘dark matter’ and ‘dark energy’. Normal matter consists of the atoms that make up stars, planets, human beings and every other visible object in the Universe.

I asked my physicist housemate and she said “nothing. The universe should be made up equal parts matter and anti-matter, so they cancel each other out. The total energy of the universe should be zero, but we’re still trying to find out where all the ani-matter went.”
