@layman,
Quote:You have implied that YOU understand Galilean relativity. Do you? Really? If so, why don't you answer the question?
Because it's a lame question only showing your ignorance of the basics, and lack of curiosity. What Galileo studied and described is now called classic mechanics, and combined with Newton's universal law of attraction, it's the theory they used to compute how to land people on the moon, and millions of other technical feats.
You don't even know what it's about, and that alone proves you are serious in your enquiry, nor curious to learn, since I HAVE ALREADY MENTIONED Galilean relativity on this thread, as the foundation for SR.
You just want to disagree at all costs with a counterintuitive theory which you don't even start to understand. Too bad.
