Question

Scientists have a theory that is accepted worldwide as the best description for positions of Earth and the sun in the universe. A group of scientists have proposed a new theory about the positions of Earth and the sun in the universe. In your own words, explain the impact of the proposed theory on science.

Answer 1

I'd say that if this new theory proves right, then the old one will have to be modified to an extent or completely discarded in favor of the new one. Then all our scientific research will have to be changed so as to accommodate these new theoretical proofs. 

Answer 2

In the event that the new hypothesis gives a superior expectation about the places of the planets and sun in the universe, then the old hypothesis must be altered or disposed of for the new hypothesis. That is the thing that keeps science "genuine". We change the models we utilize when better data goes along.
