What is 0 divided by 0?
not 0 not 1
the mass of a photon of light is 0 grams at rest and thus the photon has no mass. When a photon is released by a source it travels at the speed of light c approx (
at this speed the mass of the photon is calculated by the equation
m(i) mass at rest
m(o) mass at speed
hence the mass of a photon when moving is
Gravity can only act on a mass. As light passes around a planet or star or gravitational body, it bends. This bending of light can only be caused if the photon has mass. Thus
Also look at the affect of light on what is called a light sail.
When you have a fraction, let say
