Negative energy: same in Casimir, Hawking rad, & spherical space?

  1. Jul 12, 2012 #1
    The term "negative energy" is used
    (a) for the energy below the vacuum energy between the two plates in the Casimir effect,
    (b) the energy carried by the sister particle to the radiated particle in Hawking radiation, that is, the particle from the matter-antimatter pair which goes into the black hole, causing its loss of mass-energy
    (c) the energy which would make flat space into spherical space, or for example make the hypebrbolic space of a wormhole flat enough to make it traversable.

    If i understand correctly, these are all the same. But perhaps I don't understand correctly. Any corrections or comments would be welcome.
