Daniel effect or light illusions

The Daniel effect is the light propriety that permits a photon to be seen at the same time by different observers with both trajectories and velocities different, according to its own reality it shows that light works as it would have capacity to be transmitted in a instantaneous way.

Photon’s trajectory seen by tree different observers

The source A and receiver B are on the same referential with expansion velocity V in the universe, with a relative velocity V between them. Among the photons emitted by source A on A0 position, the one that will reach B body will be that which emission’s direction creates an angle a, that is a v function with A0B0 axle. When it occupies the generic Fn position through A0B trajectory, A and B bodies will occupy An and Bn positions, respectively. It is simultaneously seen on this position by an observer in the
absolute space that sees:
- The B body on Bn position, with velocity V in direction of B position.
- The A body on A0 position, with velocity U = V + v, in direction of A position.
- The photon on Fn position, with velocity c2 = U + c in direction of B.

By an observer on source A, whose thinks that is stopped on the An position, and sees the photon going away from him with velocity c;
By an observer on receiver B, whose thinks that is stopped on the Bn position, and sees the photon approaches him with velocity c3 = c – v.
At the exact moment that A and B bodies arrive at their A and B positions, the photon arrives at its destiny on the B body. Due to the expansion velocity V of B body in the universe and the aberration effect, c2 and c3 modify to c, giving an impression that they came from:
- A Position to an observer on the A that does not know v, so that c = c2 – U.
- A Position to an observer on the B position that does not know V, but he know v, so that c = c3 – v.

In the figure, we see that none photon went through a trajectory from A position to B position, however, the observers on the A and B referential believe in their viewpoint, as the photon would go from position A to B with velocity c. These facts are illusions, because it just would be possible if they worked as they were in an instantaneous velocity, according to Cristina effect’s explanation, because, at the moment that a photon arrives at B, A and B bodies arrive at their A and B positions, respectively.
