Web8 de set. de 2007 · Simply, no. Einsteins famous equation E=mc^2 shows us that energy and mass are directly proportional, so without mass, the value of E= 0. But after thinking some more it doesn't seem like such an easy answer. For example, light carries both energy and momentum in the form of photons, yet photons are said to be massless. WebLight has no mass, so it's momentum is can be written as p = h/λ. Where h is the Planck constant and λ is the De Broglie wavelength. The energy of an object can be determined by the following equation: E 2 = c 2 p 2 + m* 0 * 2 c 4 Where c is the speed of light, p is the objects momentum, and m* 0 * is the objects invariant mass.
