I would like to suggest that this be removed as both points (1. lack of data and 2. divergence from relativistic predictions) were disproved by the publishing of [http://iopscience.iop.org/0004-637X/722/2/1030/ this paper] in The Astrophysical Journal in 2010.

==Force acting on a mass==

==Force acting on a mass==

The example, "The logical problem of a force which is applied at a right angle to the velocity of a relativistic mass - does this act on the rest mass or the relativistic mass?" needs to be rephrased to be more clear.  Are we talking about measuring the force applied to the object or the change in trajectory of the object?  The force acts on the object, but the sentence is phrased as if there are two different objects.  The force will cause the trajectory of the object to change, which can be measured in specified frames of reference.

The example, "The logical problem of a force which is applied at a right angle to the velocity of a relativistic mass - does this act on the rest mass or the relativistic mass?" needs to be rephrased to be more clear.  Are we talking about measuring the force applied to the object or mesuring the change in trajectory of the object?  The force acts on the object, but the sentence is currently phrased as if there are two possible different answers.  The force will cause the trajectory of the object to change, which can be measured in specified frames of reference.

 

A good example would be a particle accelerator, or synchrotron.  A charge particle is traveling at speeds that approach the speed of light.  A magnetic field is applied to the particle to keep it traveling in a circular path.  As the speed of the particle increases, the force applied to the particle must increase to keep it in the track of the particle accelerator.  The force is applied at a right angle to the velocity of the particle.  The calculations to determine the force needed to hold the particle to a circular path are well-tested and verified.
