What is vaccum? Many say its "empty" space. But what does "empty" mean? Does it mean that there are no atoms (or protons/electrons, or quarks, or strings)?
Can anyone explain this?

Vacuum is not a precisely defined term. A perfect vacuum could mean a space where the air pressure is 0 (That does not necessarily mean that it is empty of matter - just that there is no pressure (matter could have solidified, for example) - or it could mean a space devoid of all matter, although a better term would be "free space".Swapnil said:What is vaccum?

Vacuum or empty space is an area that contains no matter or particles. It is a volume of space that is devoid of any substance.
Vacuum can be created by removing all particles from a specific area, either through physical means such as suction or through chemical reactions that eliminate particles.
While vacuum may appear empty, it is not completely devoid of energy. There are still trace amounts of energy present, such as electromagnetic radiation, which can be measured in a vacuum.
Yes, certain particles and waves can exist in vacuum, such as photons and virtual particles. However, most matter cannot exist in a complete vacuum as it requires particles to interact and maintain its form.
Vacuum is important in scientific research as it allows for the isolation and study of specific phenomena without interference from external particles. It also plays a crucial role in various technologies, such as vacuum tubes and semiconductors.
