Two uncharged, parallel conducting plates a gap d apart attract with a pressure of π²ħc\/(240 d⁴), about 1.3 millipascals at 1 µm. Hendrik Casimir predicted it in 1948, and Lamoreaux measured it in 1997. Whether it shows vacuum energy is debated, since Jaffe derived it without that picture in 2005.
