The term "space" as it is most commonly used means "vacuum", and is assumed to mean "the absence of any matter" or a "Perfect Vacuum". In that sense the universe is not mostly made of space because there is very little evidence of a perfect vacuum outside of laboratories. However, the majority of the universe is filled with a partial vacuum where there is an extremely low amount of matter (on the order of one or two hydrogen atoms per cubic meter).
If, on the other hand, you are asking if the universe is made of Space as in the area in which matter exists then the answer is still no because not even space can exist within itself. Space, used in this way, describes the shape of the universe.
it is mostly made of space
empty space
The universe is mostly made up of dust, stars and empty space. The universe is so large and grows daily, so that means that even more empty space is added to the universe daily.
The universe isn't s fabric. The universe is mostly just vaccum, which is like air but with absolutley no particles. My guess is that the 'fabric' of the universe is space-time.
D: Empty space.
Answer: Atoms. Yes but hydrogen is the element most abundant.
The universe is around 70% dark energy (a.k.a. empty space). The rest is mostly dark matter, with a few percent for ordinary matter. That is the current scientific model.
well the universe is endless, but the universe is made up of many galaxies, and galaxies are made of planets and stars and dust etc.
he discovered the atom was mostly made up of empty space
The universe IS space, plus everything that's in it.
Dark matter.
He discovered that the atom was mostly made up of empty space.
