Newton couldn't explain or predict that starlight passing near the sun will be bent by 1.75 arcseconds or that Mercury's orbit would precess by 43 arcseconds per century or that gravity could produce a redshift. But Einstein could. * What do you think you've established? That GR is superior to NM? We already knew that! But what we don't understand about gravity is truly mind boggling, but only for those with imagination.

I don't understand why you believe that muons are always moving at close to the speed of light relative to us. * Where did I make that claim? Nowhere. Never. AG *Muons are routinely made in the lab by smashing protons into carbon, and they can be moving at any speed. And muons have a negative electrical charge just like the electron so they can be easily manipulated; in fact the muon is identical to the electron except it is 207 times as massive and has a half-life of 1.56 *10^-6 seconds, which is very very long by particle physics standards. * So if we have two labs, one atop a mountain and another on the Earth's surface, will they measure different half-lifes?
