The reality is newtonian physics is still taught in college because for the vast majority of what people need physics for it is close enough to correct as to not matter.
I come back to this: even if we are wrong, whatever is correct still needs to fit all the observations that we have done to date. I don't know what we will know in 1000 years. Euclidean geometry is over 2000 years old and still considered correct (though we have expanded on it a lot - see in particular non-euclidean geometry)
