Insofar as you continue to practice Trump physics (in refusing to acknowledge simple facts), your comments are totally worthless. For you "postulate" is a dirty word when applied to physics. You can use "principle" if you ever choose to cease your dishonesty. The invariance of the SoL in SR is exactly that, a POSTULATE or PRINCIPLE, from which Einstein DERIVED the Lorentz Transformation. As for Planck's black-body radiation law, the MATHEMATICAL DERIVATION, the link for which I posted, is based on several assumptions. Of course, all physical theories must be validated by experiments, but you use that fact to ignore the process of evolution of physical theories. As for you comment on conic sections, you seem to deliberately ignore the fact that in physics we use idealized cases to reach important insights. The reasons for your foolishness is obvious. In physics, you are a despicable Trumper with an invariant agenda; to make up self-serving facts and interpretations which serve a simple minded purpose; make you feel good, which can be reasonably characterized as stupidity.
