| Feb 2, 2014 at 22:23 | comment | added | Friedrich | To quote Weinberg in "The Quantum Theory of Fields" quoting Schwinger: "The picture of an infnite sea of negative energy electrons is now best regarded as a historical curiosity, and forgotten." | |

clarification after comment

| Jun 9, 2013 at 13:54 | comment | added | anna v | The antiparticle is a hole in the negative energy sea and thus instead of -E it has E, so the annihilation has E_negative_hole +E_postive is all positive energy. The supposition is that all the negative energy states are filled up, except if a hole exists, which is then interpreted as a positive energy antiparticle. | |
| Jun 9, 2013 at 12:59 | comment | added | moray95 | So what about the total energy energy coming from the collision of the particle and anti-particle? | |
