Space Vacuum
Space is a partial vacuum.
Space vacuum. In the solar system space contains on average five atoms per 1cm 3. A vacuum is space devoid of matter. Ultimately a perfect vacuum isn t possible because quantum theory dictates that energy fluctuations known as virtual particles are constantly popping in and out of existence even in empty space.
Its different regions are defined by the various atmospheres and winds that dominate within them and extend to the point at which those winds give way to those beyond. It is also structured forming the heliospheric current sheet. It sustains high vacuum simulates thermal radiation and produces cold environments via a cryogenic cold wall.
What would happen if you shot a gun in space. Geospace extends from earth s atmosphere to the outer reaches of earth s magnetic field whereupon it gives way to the solar wind of interplanetary space. The word stems from the latin adjective vacuus for vacant or void.
Even in interstellar space there are still a few. Space is almost an absolute vacuum not because of suction but because it s nearly empty. Interstellar space between stars contains around one atom per 1cm 3 while intergalactic space between galaxies contains 100 times less.
By definition a vacuum is devoid of matter. It s possible that they would have some problems with their eardrums including a rupture but maybe not. Because outer space has very low density and pressure it makes something very close to a vacuum but it s still not a perfect vacuum.
Space is sometimes described as a vacuum better than mankind could create in any laboratory. A vacuum is defined as a space devoid of all matter. But it is not a vacuum but a tenuous plasma carrying the interplanetary medium solar wind.
