Modern science presupposes confidence (or faith) that the same
physical laws always apply throughout the universe.Actually, the
"confidence" that scientists have regarding physical laws
applying to places beyond our local surroundings isn't a "faith"
issue. It's a result of empirical observations coupled with
parsimony (aka "Occam's Razor"). That leads us to a very
reasonable working assumption of the same physical laws applying
throughout the universe. The same laws of physics developed by
Galileo, Newton, Einstein, etc to explain the motion of objects
on our Earth also appear to work very well in space for
predicting the paths of artificial satellites and space probes,
planets, and stars. The same spectrographic pattern that
indicate the presence of chemical elements observed on the Earth
are also observed in planets and stars far away from us. One
simple explanation to explain the commonality in physical and
chemical observations on the Earth and in the heavens is that
the same physical laws apply in both
