Is black... Nothingness?
What is it? Do you think space has a sort of atmosphere? Is it infinite? What is infinite?

Space possibly appears black to human sight because it is chemically between 75 to 78% hydrogen. A compound of hydrogen can cause things to appear black. Space is actually a deep sapphire blue. An example is the Black Sea, which has a high concentration of hydrogen sulfide. Interestingly enough, water appears blue as the hydrogen sulfide in the Black Sea makes it appear almost black, and while space is also blue but the concentration of hydrogen may cause it to appear black to us.
The best way to describe the color of the universe is "dark". Black holes are black but space is merely dark.
No, black is not nothingness. If something has a color it is something, not nothing. Nothingnes, which probably does not exist, would not have a color. Space is a kind of energy that possesses many forms of energy, matter, particles, elements, chemicals and compounds. Space has no atmosphere. Space is not infinite but is finite. There is nothing know within the universe that is infinite except for time. Sizes and masses are not infinite.

The only part of space that is truly black (and I mean the true absence of light) is black holes. The force and mass of black holes is so strong that even light cannot escape.
It does not have atmosphere, but it does have concentrations of gasses (that lead to stars, planets, galaxies, etc.) that provide light and can make space look purple-ish.
It's feasible to say that it goes on forever, but we can only see universe as far as light can penetrate. Because the universe is 14.1 billion years old, we can only detect space up to 14.1 billion light years (and counting) from here to any given point in space.

"the sky is blue"
The "sky" was named in a time when people didn't know anything about it. Do realize that the "sky" isn't any single object. We speak of birds in the sky just like we speak of stars in the sky. Think of "the sky" as the name for an IMAGE rather than an object. The most immediate object that is part of the "sky" is better known as the atmosphere.
