What assumptions are made in Olbers' paradox?
In Olber's paradox, the 2 most important assumptions made were 1) The Universe is infinite. 2) The Universe is static and infinitely old.
Plasma makes up about how much of the visible 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.
What did most ealy astronomers think made up the universe?
Early astronomers believed that the universe was made up of the Earth at the center, surrounded by concentric spheres holding the Moon, Sun, planets, and stars. This model of the universe, known as the geocentric model, was proposed by Ptolemy in the 2nd century.

What is visible universe made of?
It is made of atoms, ions, fundamental atomic particles.
What gas is the universe most visible of?
The most abundant gas in the universe is hydrogen. Hydrogen atoms make up about 75% of the universe's elemental mass.
What makes up the visible mass of the universe?
Matter is made of atoms, vast collections of atoms. Differences in matter are due to different amounts of protons and neutrons in the atom. Elements are distinguished by the number of protons, whereas isotopes (same element but different mass) are determined by the number of neutrons.
What is the most numerous in the universe?
Most probably quarks, since everything in the universe except light is made of it.
What gas is most of the universe made up of?
Most of the universe is made up of hydrogen gas, followed by helium. These two gases are the most abundant elements in the universe and can be found in stars, galaxies, and interstellar space.
What state of matter is most abundant in space?
Plasma. It makes up more than 99% of visible matter in the universe, and most of the invisible matter.
What element is the most abundant in the universe and all stars are made of it?
The most abundant element in the universe is hydrogen.
Most common atom in the universe?
Hydrogen is the most abundant element in the universe.
What element is most of the matter in the universe?
The most abundant element in the universe is hydrogen, which makes up about three-quarters of all matter! Helium makes up most of the remaining 25%
