Possibly neutrinos are . . . scientists right now are thinking that neutrinos travel faster than light (photons)
No, who has does not have a contractions. Whose is a form of "who" which shows possession.

The word 'whose' is both an adjective and a pronoun.The adjective 'whose' is an interrogative adjective, a word that introduces a question.The pronoun 'whose' is an interrogative pronoun and a relative pronoun.The interrogative pronoun also introduces a question.The distinction between the interrogative adjective and the interrogative pronoun is that the interrogative adjective is placed before a noun to describe that noun. The interrogative pronoun takes the place of a noun.Examples:Whose car is in the driveway? (adjective, describes the noun 'car')Whose is the car in the driveway? (pronoun, takes the place of the noun that answers the question)The relative pronoun 'whose' introduces a relative clause, a group of words that gives information about its antecedent.Example: The person whose car is in the driveway is my brother.

variable velocity can be defined as a moving body whose velocity changes with time
Since the energy of a photon is inversely proportional to its wavelength, for a photon with double the energy of a 580 nm photon, its wavelength would be half that of the 580 nm photon. Therefore, the wavelength of the photon with twice the energy would be 290 nm.
I presume you asking, "How can an atom of size about 1 angstrom absorb a photon whose wavelength is 5000 angstroms? Wouldn't the photon be too large for that atom?" The paradox is resolved in this way: the instant you start to discuss electro-magnetic radiation as a photon instead of a transverse electro-magnetic wave, then you negate the wave-length aspect of the light. Instead, you view light as a collection of photons -- particles whose "size" (if that word has meaning) is point-like -- with a specific energy instead of specific wavelength. A photon is NOT a snake-like wave, vibrating like a rubber band, with a length at least that of its wave-length, as it moves through a medium. A photon is a point particle with a specific energy. You can describe light as a EM wave with a wave-length OR as a collection of point particles. You can NOT do both at the same time. Light exhibits the characteristics of one OR the other, but NEVER both.
ANSWER 1: Consider any solid comprising a lattice of molecules, moving at constant speed, say in the vacuum of space. The electrons within the atoms of the molecules are subatomic "objects" whose position and instantaneous velocity are best described by a probability density field equation, whose surface lies within the lattice of atoms within the solid. At any instant in time, the position and velocity of the electrons is not a constant, whereas the "speed" of the electrons which is their velocity averaged over say one second is the same as that of the solid comprising the lattice of molecules. ANSWER 2: Consider a "photon" of light which may be regarded as an object (since it is a fundamental particle). As we all know the speed of light is a constant = C. However when passing near a massive object (eg black hole) the photon travels along the shortest path of the curvature of space-time in the vicinity of the massive object. Relative to the photon, its speed is and always has been = C. However when the speed of the photon is measured by a distant observer, it appears that for the period while under the influence of the curvature in space-time near the massive object, the velocity of the photon has varied. Hence the apparent shift in position that occurs when stars are observed in the vicinity of a black hole. In the limit, at the event horizon of a black hole, photons are apparently "slowed" to the extent that their velocity is no longer measurable by the remote observer, hence the inside of a black hole is "black", devoid of light.

If an external force is acting in the westward direction on the body that is greater than any eastward force or velocity the body has, then the body will experience an acceleration directed west even though its velocity is directed east.
No, element is a unique existing in the universe. But elements are made up of sub atomic particles. Some sub atomic particles have mass and some other don't have. So simplest form of matter is the photon whose rest mass is zero. Yet it has momentum. That is the quantum of energy. Energy is the ultimate reality.
