hi,
does anyone know why vacuum energy has negative pressure?
is it only experimental or it is theoretical too?
i also wonder if the negative pressure of the Casimir effect is absolutely negative or if it is relatively negative relatively to the rest of the laboratory?
i would be grateful for any reply!
