#Scientists at the Collider Detector at Fermilab collided protons and anti-protons in 2008. According to Special Relativity, the energy released in such a collision should equal the initial kinetic energy of the colliding particles plus their rest mass energy. The researchers saw more muons than they expected, some particles appearing to originate outside the pipe containing the collision.<ref>http://www.newscientist.com/article/dn15115-has-new-physics-been-found-at-the-ageing-tevatron.html</ref> | #Scientists at the Collider Detector at Fermilab collided protons and anti-protons in 2008.
