What Is The Vacuum Of Space

It is a condition well below normal atmospheric pressure and is measured in units of pressure the pascal.
What is the vacuum of space. But the vacuum of space is the opposite. What is the vacuum of outer space a pure vacuum is a space void of matter. The word stems from the latin adjective vacuus for vacant or void an approximation of a vacuum is a region with a gaseous pressure much less than atmospheric pressure. Vacuums are a lack of anything.
W hen we say outer space the space outside the atmosphere of planets and stars is a vacuum or is empty we really mean that outer space is nearly empty or almost a perfect vacuum. This definition is referring to a high or hard vacuum. Outer space is not completely empty it is a hard vacuum containing a low density of particles predominantly a plasma of hydrogen and helium as well as electromagnetic radiation magnetic fields neutrinos dust and cosmic rays. Vacuum space in which there is no matter or in which the pressure is so low that any particles in the space do not affect any processes being carried on there.
Everything between the earth and sun is a vacuum. The word stems from the latin adjective vacuus for vacant or void. Outer space or simply space is the expanse that exists beyond earth and between celestial bodies. Figure 1 illustrates that relationship of absolute and gauge pressure with 0 psia equal to a high or hard vacuum.
Space is almost an absolute vacuum not because of suction but because it s nearly empty. An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. A vacuum is space devoid of matter. Millions of miles separate the two relatively small objects.
If the universe had no emptiness almost emptiness as the posters before me have stated we would not use the word space for it. So space by its very definition in english language is emptiness. Space is a vacuum because the word vacuum means empty space. Imagine how far the earth is from the sun.
By definition vacuum is a space that is partially exhausted as to the highest degree possible by artificial means such as an air pump.
