What is a vacuum in physics?
3 Answers. In Newtonian mechanics this term is pretty easy to define – vacuum is a region of space free of matter. In quantum mechanics, things get a little bit complex, for more details I recommend you to read the corresponding section of the Wikipedia article you’ve put the link to, it explains the term well enough for a beginner.
Is space considered a vacuum?
Space is considered a vacuum. Space does contains matter, but the pressure is much lower than what you would find on a planet, for example. A vacuum cleaner sucks up debris because it creates a pressure difference between the area to be cleaned and the suction tube.
Does matter exist in a vacuum?

What is the value of vacuum energy without gravity?
Now the valueof the vacuum energy is a subtle thing. Without gravity only energy differencesmatter, so you can always set the vacuum energy to zero. But with gravity it is tricky, because all energy gravitates. Indeed, physicists now believe that empty space has an energy density, now known as dark energy.
