  Weak gravitational waves that fill the Universe are enough to disturb quantum superpositions and ensure that large objects behave according to classical physics.

  Constraining the Photon Lifetime
  lnkd.in
  Photons could conceivably decay, but new analysis of the cosmic microwave background shows that a visible wavelength photon is stable for at least 10^{18} years.

Jack Sarfatti "Using the largest allowed value for the photon mass from
other experiments, we find a lower limit of about 3 yr on
the photon rest-frame lifetime. For photons in the visible
spectrum, this corresponds to a lifetime around 10^18 yrs."

Jack Sarfatti That's a hundred million times the present age of our observable universe since the Big Bang.
