At small energies the speed of light approaches a constant which is the usual speed of light that we've measured. If the new speed of light is a function of energy c(E), then it's in the low energy approximation c(E) \approx c(1+ \alpha (E/m_p) ), where \alpha is a constant (should be of order 1), m_p is the Planck mass and cSabine Hossenfelderhttps://www.blogger.com/profile/06151209308084588985noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-89948587541397146812010-03-10T05:20:38.098-05:002010-03-10T05:20:38.098-05:00Hi Bee,
