Does this mean that the positron is “really” an electron moving backward in time? No, that is only one physical interpretation of the “Feynman graphs”; other interpretations, just as valid ...

At an electron-positron collider ... The laws of nature are not the same forwards and backwards in time. After seven years, it's time the world felt the impact of this discovery.

For example, an electron has a negative charge but its antiparticle, a positron, has a positive ... paired with an anti-universe running backwards in time. At first glance, this might sound ...

This has some fun theoretical applications, for example where an electron moving forward in time can be thought of as a mirrored positron (the antimatter equivalent) going back in time.

The Higgs boson is the most intriguing and unusual object yet discovered by fundamental science. There is no higher ...
