    Gravitional frequency effect

    (G*M) / (r * c^2) = (wo - we) / we "wo" is the wavelength of the photon as measured by a distant observer. "we" is the wavelength of the photon when measured at the source of emission. and "r" is distance w = c / f (c=speed of light)---------------- Pooya Afaghi
  2. P

    Light speed and time.

    According to special theory of relativity, when speed limits to speed of light, energy (kinetic energy) limits to infinity. because mass limits to infinity. m2 = m1 / SQRT(1 - (v/c)^2) *when we approach the speed of light, necessary amount of energy is too much !

    Light, Mass and Black Holes.

    [In some holy books it's a famous statement: "God is light of Earth and skies"] You spoke about photon while we don't know about nature of light yet. In some cases we say light is photon and some others we say light is wave. --------------- Pooya Afaghi

    Light, Mass and Black Holes.

    to: bernhard.rothenstein >> Yes, p=mc >> p=(mc^2)/c >> p=E/c >> p=hf/c >> p=h/w (E=hf, f=c/w, E=mc^2) (p: momentum, w: wavelength)-------------------- Pooya Afaghi

    Light, Mass and Black Holes.

    Pooya Afaghi The photon has only relativity mass that depends on photon wavelength. One important thing is that photon has NOT any mass in speeds less than c (~3*10^8 m/s) and we don't have static photon. Note1: Today we say "photon has momentum" instead of "photon has mass" Note2: Light is...
