Is/does space have matter?

Question

I mean the blackness in between objects.

Answer 1

Yes. The solar wind, which causes the Aurora Borealis, travels through space and it is made up of particles such as neutrinos, so there is matter in the black "empty" space... the particles are just relatively few, far between, and very small.

P.S. Radio, light, x-ray, and gamma waves which travel through space are all electromagnetic (EM) radiation. I don't recall ever hearing that EM radiation needed a medium to travel through as does sound. Sound waves need a medium because they are compression waves, so they don't travel through space. (If you were floating out in space it would be completely quiet, you could watch a planet explode and it wouldn't make a sound.)

Answer 2

I just answered another question like that.

No one knows for sure. There are postulates and theory, the problem is WE SHOULD be able to detect or prove it with Newtonian and Relatatvistic physics but we CAN'T.

There are several postulates. Light and dark matter. Particle, maybe space is made up of quark like things.

The most prevailing but elusive theory was the Aether, the problem is all attempts to prove there is an Aether (atmospher) in space don't pan out.

The big mystery is HOW do radio and light waves travel through "nothing"

How do WAVES propegate through NOTHING.

So there must be SOMETHING
or there is SOMETHING about waves are are still not aware of.

Answer 3

Interstellar space isn't quite a vacuum. The estimates have a pretty broad range, but the most common seems to be about 1 atom per cubic centimeter.

Answer 4

Look down at your feet. The Earth is in space, and it is made of matter.

Look up at the Moon. The Moon is in space, and it is made of matter.
