Isaac Newton was a great scientist, perhaps the greatest of all time. If Newton's view of gravity had been accepted as “settled science”, then Einstein's view never would have been considered, and Einstein himself would have been ignored, even shunned.
And any evidence supporting Einstein would have been cooked to make it appear that Newton was right.
Ain't settled science great?

When it comes to science, the fat lady never sings.
