The Casimir Effect was first predicted by Dutch physicist Hendrik Casimir in 1948.
In his groundbreaking paper, Casimir theorized the existence of a force that arises between two uncharged, parallel plates in a vacuum.
It is caused by the fluctuations of virtual particles in the vacuum.
According to quantum physics, empty space is not truly empty but is filled with a sea of virtual particles that constantly pop in and out of existence.
The Casimir Effect results in an attractive force between the plates.
Due to quantum fluctuations, more virtual particles are created outside the plates than between them, leading to a pressure imbalance that pushes the plates together.
The effect is extremely small but has been experimentally confirmed.
Scientists have successfully measured and observed the Casimir Effect using highly sensitive equipment in laboratory settings.
The Casimir Effect is a manifestation of the fundamental forces of nature.
