In classical physics a perfect vacuum contains no matter.
However in quantum physics the Heisenberg uncertainty principle prohibits such a condition, requiring that even a perfect vacuum must contain particles of both matter and antimatter being continuously created and annihilated, each particle existing for only a very short period of time.
However in the real world creating a perfect vacuum is as impossible as reaching absolute zero temperature. Thus any practical vacuum will always contain very tiny traces of gas.

∙ 10y agoVacuum is the absence of matter or a space empty (or relatively empty) of matter. A vacuum may be defined also as a space in which the pressure is significantly lower than atmospheric pressure. Vacuum is the state of emptiness (or void) of matter.

A blank is a space without matter?
A vacuum
What happens to the sound waves when it enter into vacuum?
Sound waves cannot propagate in a vacuum. Sound waves travel through matter, and a vacuum is, by definition, the absence of matter.
What state of matter does light travel the fastest?
Light travels fastest in a vacuum. Other than that, it would travel fastest in a very dilute (low-pressure, and therefore low-density) gas.
How does a medium (matter)affect the speed of light?
When light goes through any medium other than a vacuum, its speed is normally slower than in a vacuum.
Does absolute vacuum exist in a black hole?
No, a black hole contains a lot of matter and thus has a huge gravitational pull. Absolute vacuum doesn't exist anywhere we know of.
Does matter exist in a complete vacuum?
The matter exists in everywhere, include the vacuum.
Is a vacuum an absence of electricity?
No, a vacuum is an absence of matter.
Does heat travel in a vacuum?
Lets look at a vacuum and heat. Heat is the treansfer of energy from one piece of matter to another. A vacuum is the absence of matter. Heat cannot transfer in a vacuum because there must be matter in close proximity to other matter for heat to travel.
What fills the space in a vacuum?
Nothing: a vacuum is the lack of matter.
Example of no matter?
A complete vacuum contains no matter.
Is there a place existing where there is no matter?
In a vacuum no matter exists.
Which animal can respire in vacuum?
none, because you need oxygen to respire and a vacuum is the absence of matter and oxygen is matter
Can there be an absence of matter?
There is no space where there is no matter. Even in a vacuum, matter, no matter how miniscule does exist.
Where can matter be found?
Matter is everywhere. Where there is no matter , it is a vacuum. You as a biological organism are matter.
What does a vacuum not contain?
A vacuum by definition is an area in space devoid of matter.
Does heat exist in a vacuum?
No. Heat is a measure of molecular energy in matter, a true vacuum would not contain matter. However, since there is no such thing as a complete vacuum, then Yes.
In a vacuum there is no matter. do you think conduction can take place in vacuum?
Conduction cannot occur within a vacuum because it requires a substrate (i.e. matter) for energy to be transferred.
