but classical physics *is* part of modern science. Our understanding is
deeper now, but we still use Newtonian gravity over 99% of the time because the
equations are simpler and it’s more than accurate enough for most
purposes. The same applies to Newtonian dynamics; 99% of the time you
don’t have to care about relativistic mass increase with velocity. A
million years from now, Newtonian gravity will still be applicable if there are
humans on Earth. [Newton himself knew, by the way, that his theory wasn’t
quite there – he accepted instantaneous action at a distance most reluctantly
because he could find no way around it. That’s been fixed now, though
general relativity is still under persistent challenge (even special relativity
is under an unusual degree of challenge at the moment from these neutrino
experiments). If GR is superseded, it will still be useful in many domains
though, because it’s a safe bet that the equations of the more accurate theory
will be even harder.]</DIV></DIV>
