Actually that's a common claim by people who never took a physics class, but feel for some strange reason that they master the subject. Of course since they have no knowledge of the facts, they attack the only icons they've ever heard of. They have no idea whose research Einstein blended together: Fitzeau, Michelson & Morley; Poincare & Lorentz; and Maxwell, Gauss, Ampere, Faraday & Coulomb, just to name the central figures. And of course to even get started understanding this, you need at least 2 yrs in a college physics curriculum just to get started. From there you need to do actual research and study the experiments that were done that led to the discoveries of the laws in question, and -- most importantly -- why this crowd of people were correct. And it's because they were all not only brilliant, but also intensely curious in collecting evidence, and digging into it to discover what it revealed.
