What is space made of? If there is an estimated one atom per cubic meter of space, what else is filling up space?
Answers
Space that we can see is mainly very very empty. If you ignore the galaxies and stars, then the rest of space is mainly a vacuum, so there's no particles at all. The particles that are there are mainly hydrogen and helium, which form a plasma called the Intergalactic Medium.
In interstellar space, the density is about one atom per cubic meter. If you are in, say, the Orion nebula, the density is higher: about 10 atoms per cubic centi-meter or about 10^7 atoms per cubic meter.
Explanation:
From Wikipedia, the free encyclopedia. In mathematics, any vector space has a corresponding dual vector space (or just dual space for short) consisting of all linear forms on. , together with the vector space structure of pointwise addition and scalar multiplication by constants
