When scientists rejected the continental drift were they using the scientific process?
No, because the scientists did not have a hypothesis
How do the scientists know the universe is expanding?
The main piece of evidence (there are others) is the redshift from distant galaxies. This is usually interpreted as a result of the Doppler effect - i.e., the galaxies are moving away from us.
