Is space nothingness? Or does it have mass and other physical properties? Bring on your religions (Relativity, Big Bang, Quantum Mechanics) to answer this one.
Yes, it is nothingness. case closed!
Dark matter has recently been proven to exist in space just as described by Einstein. Dark matter is what is causing the expansion of the universe. Dark matter and space has nothing to do with religion.
"Space is temperature"?
Temperature is defined as:
the degree or intensity of heat present in a substance or object, esp. as expressed according to a comparative scale and shown by a thermometer or perceived by touch.
I don't know what that has to do with space?
Space is the largest collective of visible and invisible energy known to humans.
It is the stuff that is itself everything and from which everything comes.
Therefore space is completely full, not empty or void of.
In the most simplified terms: space is neutral light.
"If we put a thermometer in darkest space, with absolutely nothing around, it would first have to cool off. This might take a very very long time. Once it cooled off, it would read 2.7 Kelvin. This is because of the "3 degree microwave background radiation." No matter where you go, you cannot escape it -- it is always there."
"2.7 Kelvin or 2.7 degrees above absolute zero ( -270.7 degrees Centigrade"
What you have is solar molten, which when cold gives you solid matter.
Any space that isn't composed of dark matter (black holes and similar objects) or normal matter (planets, stars, asteroids) is composed of dark energy. Dark energy makes up over 70% of the matter/energy in the universe due to filling all spaces between any other forms of matter and energy. It is too miniscule to be seen through direct laboratory observation, so the evidence we have of it is indirect, based on the accelerating expansion of the universe and the theory that it has negative pressure, repelling everything close to it and attempting to spread out. It doesn't seem to be affected by the fundamental forces that keep the universe and matter working in its proper fashion, besides that of gravity which can be seen through its negative pressure and effect on other matter.
Due to not having instruments that we can use to observe and measure the effects of it and current theory having a few errors, we don't know much more than this.
I don't believe in dark matter nor do I believe the universe is expanding.
Speculation without evidence is religion.
We can't observe dark energy, but we can observe the universe expanding. Dark matter can be indirectly observed in areas where there is a lack of background light due to it having such a heavily gravitational pull as to suck light into it. As well as that, rotation of some solar systems and many galaxies are centered on points in which we see no light, leading to the conclusion that black holes and dark matter exist. Light does have weight and is affected by gravity and seeing as galaxies even exist in the first place instead of the universe just being a random collections of planets and stars gives the logical impression that there are entities of such gravitational pull that they can suck in light.
Then, it's a good thing this thread is in the religion forum.
"gives the logical impression that there are entities of such gravitational pull that they can suck in light."
I am now outta here, but it makes no logical impression whatever.
Suns hold solar systems together and galaxy centers may well hold

Wouldn't seem to require any dark matter or expanding universe.
Did you read that whole article? It talks the black holes at the centers of galaxies and their effect on star formation. Galaxy centers ARE black holes, and black holes are formed from dark matter, just a mass of super-compressed subatomic particles in a uniform homogenized mass that have such a gravitational force that entire galaxies revolve around them.
Please do some research and don't give evidence AGAINST your point.
