You are complaining about my statement that Newton's law of gravity is
still accurate, and was accurate 1 billion years ago, and will be accurate
in 300 years.

I can't find any precise information, but my guess (if you like,
faith) is that the gravity law is accurate to more than six
decimal places over extraordinarily large ranges (describing objects with
mass less than a microgram, and objects with mass more than the earth, and
working for distances less than a micrometer, to more than the diameter of
our solar system).

I did find a statement at
http://en.wikipedia.org/wiki/Gravity
to the effect that the gravity law has an error of
    43 arcsecond per century
    [1% of one degree PER CENTURY]
when predicting the precession of the perihelion of the orbit of the planet Mercury.

An error of 1% of one degree per century (and some other mind-bendingly
minute discrepancies) proved that Newton's gravity law was wrong!

If anyone here has ever made a substantive statement with a better accuracy
than Newton's gravity law, please tell us now!
