From an unusual perspective, this article examines the experimental confirmation of the spacetime deformations predicted by special relativity. A perspective that includes three relevant critical aspects: the necessary symmetry (never verified) of the experimental confirmations; the universality of the relativistic deformations, always suspiciously independent of the physical and chemical nature of the deformed or altered objects (e.g., rulers and clocks); and the absence of direct physical causes of those deformations and alterations, the only cause being the fact that the deformed or altered objects are always observed in uniform motion. Apart from remembering that such experimental confirmations could also be confirming other theories (e.g. H. Ives' theory of absolute space and time), we consider here the possibility that the observed and measured relativistic spacetime deformations are only apparent deformations, as in the case of refractive deformations; or that they are the consequence of making observations and measurements in a supposedly continuous spacetime that in reality is discrete (discontinuous). In any case, this article demonstrates that certain relativistic deformations are incompatible with some basic laws of mechanics, as is the case with the pendulum that oscillates faster in one direction than in the opposite direction; or with the force-free elastic band that is observed to be stretched more in some places than in others.
