Dark matter, called so because we can't see it. It's mainly in tiny particles, propagated from the dark energy field. It's thought to make up anything between 25% and 94% of the matter in the universe, estimated by the amount of gravity it exercises. Much is concentrated in places like the galactic halo, and the 'bow shock' of the heliosphere. It can also be absorbed back into the field as energy. The exchange rate for 1 unit of energy in this process is the mass multiplied twice by 299,000. (k/sec. i.e. e=mc2).
A vacuum is a space devoid of matter, where the pressure is lower than atmospheric pressure. It is commonly found in outer space, with very few particles present.
Outer space is a vacuum, which means it is mostly empty of matter, including oxygen. Instead, outer space contains elements such as hydrogen and helium, cosmic dust, and various forms of radiation. It is the absence of atmosphere that makes it challenging for humans to survive without life support systems.
In Outer Space was created in 1983.
Tagalog Translation of OUTER SPACE: sa kabilang daigdig
No, one ton would not float in outer space because weightlessness in space is due to the absence of gravity, not because of buoyant forces. In space, objects with mass will still have weight but will appear weightless due to the lack of a gravitational force pulling them down.
No, they are properties of matter. Outer space has the properties it has because it has little to no matter.
yes
the black hole is a matter in outer space that is made by the force of gravity
yes. yes. yes.
There is no true vacuum in outer space (or anywhere!). Very very roughly, if something 'froze' in outer space, the 'energy' would convert into 'frozen matter'.

cosmic dust
About 100 tonnes of "micrometeorites" litter Earth every day.
Organisms from earth, cannot live in outer space. They need a stable environment and a place to evolve and reproduce. Outer space, does not have a stable environment it gets hot then cold in a matter of seconds. If you really think about it, what would the organisms eat? There's nothing in outer space that would provide them with food.
the amount of matter in a given space; mass per unit volume
Space can be occupied by matter. If not how do planets move? If you're asking: Does outer space have matter? Then I would say yes, but very little, little enough to be called a vacuum. Outer Space has a few atoms per square meter.
