Albert Einstein, who is not quite current but who is at least relatively recent, did actually revise Isaac newton's original theory of gravity, and even now, many other theoretical physicists are trying to improve on Einstein. As for Newton's laws of mechanics (force equals mass times acceleration, and so forth) nobody is trying to improve on those. As far as we can tell, Newton got that exactly right.

If they are mathematicians they can prove a theorem. In the physical sciences theories cannot be proved. The current theory is the one that fits the experimental evidence more closely than all alternative theories. When a new theory comes along that is more accurate, the old theory is superseded.

He was an Italian scientist of the 17th century. He did not prove the heliocentric theory. But everyone accepts the heliocentric principle now, after it was proved right; but that happened long after Galileo's time, after new scientific discoveries in the latter half of the 1600s.
they made inventions to prove that current electricity is there.

Newton published it in 1686 in his Philosophiæ Naturalis Principia Mathematica ("the Principia").
