We know from Faraday’s Law that light is electromagnetically active. The
ramifications of this are elaborated on in Photoelectron Equivalence
Principle. Now that we know that light can thereby exert a pressure upon
bodies of mass, known as radiative pressure, we can apply this to galaxies
as a whole.
As photons tend to exert a positive force upon bodies of mass, we should
see galaxies traveling away from each other, as is the current observed
trend with few exceptions. There ought be a general increase in speed that
galaxies are moving apart, with an exponential decrease in increased
acceleration as they drift further apart. The reason for this is that as
stars drift further apart, the probability of an individual photon from one
star hitting another star will decrease at an exponential level due to the
inverse square law. Therefore, as galaxies move farther apart, they will
exert less and less pressure on each other.
The universe is a slightly more complicated system than this, however, with
all galaxies acting upon every other galaxy, and as such the rate of
decreased influence will taper off at an even steeper curve as the whole
system expands.
