If the universe has walls, we don't know anything about them yet, because
we've never yet been able to see far enough to spot them. However, you
should be aware that all of the best current work in astronomy, cosmology,
physics, and also western religion I think, agrees that the universe doesn't
have any walls.
Hydrogen
Hydrogen is the most abundant element in the universe.
If you define the "visible universe" as objects emitting light or electromagnetic radiation that can be seen or visualized from earth, then plasma makes up essentially all of it.In our solar system, the sun which is more massive than all the planets is made up almost entirely of plasma. Of course, the planets with perhaps the exception of the gas giants are made up of normal matter. But, they are just a tiny drop in the universe. We are unable to see planets in any of the other billions of solar systems. A few planets have been postulated, but are essentially invisible from earth.Even if we assumed every star had planets like our sun, the mass of these planets would be negligible.If you include all the blackness of space, then it is probably mostly void of matter, although the matter that is there would still be ions and plasma.
Plasma makes up about 99% of the universe because it is the most abundant state of matter at extremely high temperatures, such as those found in stars. Stars, being the most common objects in the universe, consist mainly of plasma. Additionally, plasma is highly energetic and interacts strongly with electromagnetic forces, making it prevalent in space.

The Universe is everything . So, Aluminium makes up part of the universe: a tiny fraction of it.
cellulose
Hydrogen
Compact bone.
Cellulose.
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.
Cellulose makes up the cell walls of plants, and is broken down during the cooking of potatoes as they have cellulose as they are classified as a plant.
Cellulose makes up the cell walls of plant cells. Cellulose is composed of glucose molecules.
cellulose
None of the things that make up the universe measure up to 90 percent. The highest percent is 73 percent and that is dark energy.
cellulose is the strong substance that makes up cell walls.
Hydrogen makes up about 75% of the universe by mass. It is the most abundant element in the universe and can be found in stars, gas clouds, and planets.
