Newton's equations are quite sufficient to navigate our satellites and space probes. There is nothing at all in our everyday experience that can distinguish Newtonian physics from relativity.

Yes. Newtonian physics is useful for now, though false.

Yes. Newtonian physics is useful for now, though false.Science does not deal in the truth or falsity of ideas, only their utility. An assertion of fact can be true or false; an observation can be accurate or inaccurate; people can be truthful or deceitful -- but theories are useful or not useful. They are not true or false.

There is nothing false about Newtonian physics; it simply fails to map to observation in extreme cases. Ultimate, all physical theories meet this fate.

But you have cleverly led the discussion away from your original misstatement, whis was the assertion that scientific statements are based on belief rather than objective evidence.

I am waiting for you to find the equivalent of religious sects within the scientific community. Find me a body of scientists who do not "believe" that Einstein's equations don't map to observation better than Newton's. Yet religious believers are at each other's throats constantly over such fundamental concerns as what is permitted to eat, drink, wear, and boink.

Yes. Newtonian physics is useful for now, though false.

Not false, just not broad enough to cover all the bases. Newtonian physics works great for the macro universe of planets and suns and spaceships (though not Star Trek spaceships) -- it simply breaks down at the micro scale of subatomic particles.
