space devoid of matter
, where the pressure is significantly lower than atmospheric pressure, often achieved artificially in
laboratory settings
. It plays a crucial role in various scientific and
industrial applications
, including
physics experiments
,
electronics manufacturing
, and
space exploration
.
Concept
Ideal Vacuum
An
ideal vacuum
is a
theoretical space
devoid of all particles, matter, and pressure, representing
absolute nothingness
. This concept forms an important
baseline in physics
, yet in practice, it is unattainable, as even the best vacuums contain a few
scattered atoms
or particles and exhibit
quantum fluctuations
.
