We know that a photon has no mass, but has relativistic mass - which means in theory, a photon will have a gravitational field.(adsbygoogle = window.adsbygoogle || []).push({});

What is the total possible gravitational affect of all photons (and electromagnetic radiation) emitted from the stars in the universe?

Could this account for the gravity seen in the universe – which cannot be explained by ordinary matter?

And could this explain the accelerating expansion of the universe, instead of the dark matter and dark energy interaction that's otherwise predicted?
