What is in a cubic meter of space?

Answer 1

The empty space is not so empty.
Billions of atoms and much more photons;
1000 dm3 and 1,000,000 cm3.

Answer 2

Remotest space, if memory serves me correctly, you would find perhaps an atom in a cubic meter if you were lucky. If you are interested in astronomy, check out Astronmy Cast, a free podcast available through itunes that is imformative and formatted to be easily understandable. Ah, paydirt: Intergalactic space is the physical space between galaxies. Generally free of dust and debris, intergalactic space is very close to a total vacuum. Some theories put the average density of the Universe as the equivalent of one hydrogen atom per cubic meter[12][13]. The density of the Universe, however, is clearly not uniform; it ranges from relatively high density in galaxies (including very high density in structures within galaxies, such as planets, stars, and black holes) to conditions in vast voids that have much lower density than the Universe's average. So possibly 1 hydrogen atom per several cubic meters.

Answer 3

I was told once that there is one hydrogen atom per cubic foot in the typical vaccuum of space. A little math shows that that's roughly 30 hydrogen atoms per cubic meter. But then the universe is roughly 3/4 hydrogen, 1/4 helium, and a smattering of other stuff...

Answer 4

Any given cubit meter of space contains, radiation, comic rays, all types of light across the entire spectrum (radio waves through gamma rays), neutrinos (nearly massless particles flowing from stars), quantum fluctuations (the instability of space-time at extrmele small scales), and yes... a bunch of cubic centimeters.

Answer 5

On average out in space there would be a molecule or 2 of Hydrogen.

Answer 6

it depends on what medium is considered. It also denotes the density of matter or medium lying in one cubic meter of space.

Answer 7

In outer space near us, anything between 1 and 5 million atoms of hydrogen.

Answer 8

I am assuming you mean in a virtual vacuum, so most of the space would be empty. However, there could still be a few simple molecules, hydrogen atoms, or even free sub atomic particles.

Answer 9

A bunch of cubic centimeters

Answer 10

Asteroid
