Conventional wisdom says that Energy can be transferred between objects,...
I look at light as a form of motion that can organize and or disorganize matter as it travels.
I may be wrong in the my way of thinking.
Pmbphy ; When light travels forward is it pushed, pulled or both ?
to use force to move (someone or something) forward or away from you
to hold onto and move (someone or something) in a particular direction and especially toward yourself
Like opening a car door conventional wisdom says that's a form of energy transfer. If energy is both mass and motion then the question can be asked, " when I open the car door " was there any mass transferred?
Yes, light does appear to move only in the forward direction. Why ?
Photons travelling in straight lines automatically generate an inverse square law of intensity versus distance from a point source, by simple solid geometry. The surface area of a sphere depends on the square of its radius, so the number of photons crossing unit surface area in a given time must depend on the reciprocal of the square of the radius, if the source is at the centre of the sphere.
The answer to his question in the title is very simple. You made it appear way too complicated. The question is only meaningful when the light is directional in nature. In such cases the direction in which the light travels is defined as the "forward" direction for that beam of light.
However a single photon will travel in a straight line. It's also possible to modify the light beam to make it spatially coherent. Ideally a laser puts out a highly collimated beam, i.e. the photons are (ideally) parallel. In reality the beam is slightly divergent. That's why no laser beam will be a pencil of light forever across the universe.
I am sorry to disagree, but any normal light that is non-coherent is going to follow the inverse square law, your reference to ‘directional light’ moving in a forward direction is meaningless in this regard, the isotropy of space precludes the ‘forward’ direction.

Motion; Moment of inertia; When a wave pushes forward, the pushing effect causes a mass to deviate from going straight, and when a wave is pulled, the wave can be brought back to a node. If and when something is being pushed there will be a simultaneous opposite effect but not a pull in a simultaneous straight opposite direction, instead the mass curves back to a straight path over time. This straight path may not be in the same direction as when the mass was pushed forward ( Inverse Square Law ). Positive Motion of Inertia : Negative Motion of Inertia if there is such a thing.

Duality of pure motion devoid of mass; Always in the act of being positive and negative at the same time and quantity. With mass then being in the same or different form as well as a same or different time with respect to each other.

I can't even make sense of what he's posting.
