What is the Casimir effect?
PhysicsQuantum field theory
Quick Answer
The Casimir effect is a tiny attractive force between very closely spaced uncharged conductive plates. It arises from quantum fluctuations in the vacuum.
The Full Story
The Casimir effect was predicted by Dutch physicist Hendrik Casimir in 1948. In quantum theory, even “empty” space contains fluctuations, and placing two plates very close together changes the allowed modes of those fluctuations, creating a small measurable force. This effect is strongest at microscopic distances and has been confirmed in precise experiments. It is an important demonstration that quantum vacuum effects are physically real, not just mathematical abstractions.
