What exactly is the Casimir Effect?

Could somebody explain the basics?
The Casimir Effect is a phenomenon in quantum physics that describes the attractive force between two uncharged, parallel, and closely spaced plates. This force is caused by the fluctuations of the electromagnetic field in the vacuum between the plates.
The Casimir Effect was first predicted by Dutch physicist Hendrik Casimir and his colleague Dirk Polder in 1948. However, it was not experimentally confirmed until 1958 by Russian physicists Yakov Frenkel and Sergei D. Katsenelenbaum.
The Casimir Effect is significant because it provides evidence for the existence of the quantum vacuum and the fluctuations of the electromagnetic field within it. It also has implications for fundamental theories in physics, such as quantum electrodynamics and the nature of space and time.
The Casimir Effect is typically measured using a device called a Casimir force apparatus, which consists of two parallel plates placed in a vacuum and a means of measuring the force between them. The force is usually measured using a torsion balance or an atomic force microscope.
The Casimir Effect is a very small force and is only noticeable in extremely small distances, such as on the scale of nanometers. Therefore, it cannot be observed in everyday life. However, it has practical applications in nanotechnology and has been observed in various experiments in vacuum settings.
