LHC discovery

Salfronz asks: “When they talk about finding a particle like the Higgs boson, and looking in certain energy levels, does this really mean that the particle is that equivalent mass?  It seems like at the energy levels they’re looking at that these particles would be easily detectable if they actually had the mass to correlate [...]

Black holes and gravitons ! Anything wrong here?

If no particle can escape from a black hole, how does quantum mechanics (which postulates gravitons) explain that a black hole’s gravitational field extends beyond its event horizon? If the force of gravity is transmitted by an exchange of gravitons, they’d have to escape from the black hole. I know they’re massless, but so are [...]
