I am trying to understand the following equation:
Equation E^2 - |p|^2 c^2 = m^2 c^4, the relativistic energy-momentum relation written as plain text.

what is P?
 

Discussion

Nabeshin said:
p is the normal 3-momentum of the particle.
thank you Nabeshin
if P is momentum of a particle that already exist
how can this equation explain the create of virtual particle from nothing?
