- TL;DR Summary
- A thought experiment
Suppose a sphere were to be placed around our Sun with a radius equal to the radius of the orbit of Earth, it would have a volume of 6.266x1022 m3. At any instant in time there would be 3.846x1027 Watts of energy within this volume in the form of photons from the Sun.
Since watts= joules/sec. this gives us 3.846x1027 Joules of energy at any instant in time, which according to the Theory of Relativity (E=MC2) would give us an equivalent mass of 1.2828x1021 Kg. That is approximately equal to the mass of a small planet (Pluto =1.25 x 1022 Kg.).
You will notice I emphasize ‘instant in time’ and do not take into consideration the photons from other stars and galaxies which are traveling through this volume at the same instant.
Now expand that same concept to the entire Universe, even if only the Universe we can observe. You might notice that the Universe itself is a medium through which light travels and should be recognized to have a ‘Refractive Index’
Science ‘assumes’ a refractive index of the universe to be equal to 1. But we have no way to be certain with our current level of technology or knowledge. All we really know for certain is that our universe is one huge glob of photons and mass each acting on the other through gravity yet we do not seem to be taking into account the total mass of the total photons present everywhere, constantly.
Just a thought,
