Questions about the rationality of explanations of physical phenomena are met with the claim
that physics is counterintuitive. The justification for retaining counterintuitive explanations is that they agree with observations
and they support predictions.
An example of counterintuitivity, explaining the curvature of the path of light in a gravitational
field by defining gravity as distortion of space in the presence of matter.
It is possible to explain this phenomenon without resort to counterintuitivity. Gravity is the
mutually attractive force between each particle in the universe. To behave gravitationally is to demonstrate substantiality.
Space is intuitively insubstantial, thus cannot respond to gravity or exhibit shape.
Light responds to gravity, thus, as a hypothesis, light is substantial or particulate. This removes
the need for another counterintuitivity, that light is both a wave and a particle. A wave cannot traverse a vacuum.
The wavelike behavior of light requires a binary particle. A simple unary particle could not oscillate,
could not exhibit frequency or period.
The straight line path in the absence of gravity indicates the components are equal in mass. The
oscillation indicates dissimilarity in charge.
In this hypothesis the particles are the electron and the positron, equal in size, dissimilar in
charge. These particles constitute an element of radiation, a binary photon (bion). They travel in mutual orbit around a moving
axial center (counter quasicycloids), drawn together by their charges, tending to separate centrifugally. Their plane of rotation
contains the vector of the moving center point.
Substantial binary composition provides a rational explanation for all observed properties of light.
Path is deflected by a gravitational field but not an electric field, producing
gravitational lensing.
Plane of rotation is torqued by an electric field but not a gravitational field, exemplified
in the Kerr cell.
Particulate composition explains the photoelectric effect.
Binary particularity explains the random result of particle collisions.
Binary particularity explains single and double slit phenomena. The particles may
be paired with different partners after a slit interaction, or the interaction may result in a new emission.
Substantial composition of light suggests a hypothesis for dark matter and residual
radiation. Space is filled with randomly directed bions.
The mutual orbit suggests a hypothesis for spectral shifts and the predominance of
red over blue. Generation of bions is random. Some orbits will expand, some contract, and some will be stable. The expanding
orbits shift to red and eventually the particles separate. The contracting orbits shift to blue and eventually the particles
unite as neutrinos. Gravity augments attraction and reduces repulsion, thus observations show more bions in red shift than
blue.
