we can see from length contraction of inclined bodies to the velocity, consider situation in figure.A spaceship is moving with respect to observer 1 at velocity V. as shown in the diagram,the observer inside observs length equal to PQ. the observer outside observes length to be PS . if this is true that is the inclination of say rod PQ changes to PS then, consider figure 2. the same situation is there in figure 2 except MN or MD is a reflecting surface instead of rods. a ray of light comes from the outside of spaceship.(shown in orange colour) the angles of incidence = angle of reflection x=x' and y=y'.... (law of nature) the observer inside will see the light reflect as OAC. (say horizontal surfaces absorb light). while the observer outside will see light reflect as OBO. now if the vertical surface inside the spaceship (shown in yellow colour) is a light sensitive surface, which on incident of light triggers 'SELF DISTRUCTION CIRCUIT' of the spaceship. so observer outside should see ship blown, but observer inside light never hits yellow vertical surface. this cannot happen according to special relativity. so does the law of nature 'angle of incidence = angle of reflection' is violated/not applied? or we have another explaination?
