In Saleh Theory, since the photon has a projectile and impulsive motion, it is a particle. On the other hand, as it has a rotational motion, it behaves wavelike, and according to the explanations of how the photon is moving, we define a new formula for the energy of photon.
In 2016, a BBC science documentary entitled "The Mystery of Dark Energy" was produced for the BBC's Horizon Documentary series, in which scientists spoke about the issue and its new achievements. We define a new way to explain what dark matter and dark energy really are, in response to the ambiguities of that documentary.
