The only description that quantum theory gives for a photon is that it is some form
of energy that travels as a wave but when looked at it becomes a particle, hence
its dual nature. But ask a physicist to draw you a single photon and he would decline
because he does not have the slightest idea of what it is. Is it a wave with one
or a million peaks and troughs and if it passes through a hole smaller than itself
and spreads out as assumed for the creation of interference patterns, why does it
not continue to spread out and disperse at a much faster rate than its loss due
to red shifting?
Why doesn’t the amplitude of the wave represent the amount of energy it has, and
where exactly is the energy stored in a wave?
Photons probably present the greatest problem for scientists today.
No one knows why they move so fast nor why they can keep moving for billions of
years without spreading out when they collide with particles or why they do not
lose energy apart from that due to the expansion of space.
Speculation resulting from the dual nature of light has led to the belief that nature
will never be understood. Consequently, theories are now being proposed based upon
fantasy where more than ten dimensions can exist and multiple universes may exist
alongside our own.

With FET it is easy to visualise a single photon. FET tells us how photons are created, how they are responsible
for imparting kinetic energy into matter and for supplying it with thermal energy.
It tells us that photons are disc shaped regions of fluid energy sustained by their
rolling action that generates a centripetal force to keep them intact. It tells
us that they a have a specific diameter that is inversely proportional to their
energy content. This diameter is what we currently call its wavelength. The more
energy a photon contains the larger its centripetal force and the smaller it is.
The smallest possible photon in terms of physical size is the gamma ray and has
a diameter of 10-15m and an energy of 9.4x108eV. This is because this
photon has an energy density equal to that of solid energy and the photon therefore
becomes a solid particle i.e. a neutron. The largest possible photon in terms of
its diameter is a radio photon with a diameter of around 3,000m because the energy
density is now equal to that of the continuum and the two merge into one.
FET shows how photons can be entangled allowing information
to travel at faster than light speeds.
