The
fact that neutrinos are smaller than photons is key to understanding
how photons are affected by gravity.
In
the sea of zero-point particles, everywhere present in space,
neutrinos have the same advantage that red photons have over blue
photons in transparent media. Neutrinos roll past obstacles more
directly than photons.
Obstacles
in space includes zero-point photons. Neutrinos can therefore
overtake photons as they slalom through space.
The
fact that neutrinos can overtake photons in a race trough space was
demonstrated and confirmed a few years back, but has later been
demented by the researches who performed the experiment. However, in
the Velcro model, neutrinos must be able to do this in order to
affect photons correctly with regards to gravity.
Neutrino
in the process of overtaking a photon.
Although
both the neutrino and the photon travel at the speed of light,
neutrinos always has a slightly shorter route to travel. In a race
between photons and neutrinos, neutrinos come out the winner, just
like red photons always end up the winner over blue photons in a race
through a transparent medium.
It
should also be noted that neutrinos communicate their information
with other neutrinos. Incoming neutrinos are informed of the presence
of massive bodies through collisions with outgoing neutrinos.
Photons
do not move through an empty space, but a space filled with neutrinos
carrying information about the location and size of nearby objects.
This information includes the presence of photons.
Collisions
between neutrinos carrying information about a photon, and neutrinos
carrying information about a nearby massive object, create
under-pressure in the exact same way under-pressure is created by
collisions between neutrinos carrying information about massive
objects.
This
means that neutrinos affect photons in the same way they affect
inertial matter.
What
applies to inertial matter regarding gravity applies to photons as
well.
However,
photons behave slightly different from inertial matter under the
influence of gravity.
Unable
to slow down, outgoing photons have no choice but to loose some of
their energy through shrinkage, so outgoing photons experience a
red-shift.
Incoming
photons on the other hand cannot speed up, so they have to blue-shift
in order to keep their speed constant.
It
is only when photons travel parallel to a gravitational field that
they behave exactly like inert matter. In such cases, they will bend
towards the massive object as if space was curved.
However,
there is no curved space. All that is happening is that neutrinos
interact with photons in the exact same way that they interact with
massive objects.
