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 When a new theory comes along that is more accurate, the old theory is superseded.
Scientists first create an hypothesis. They develop methods to prove their hypothesis. In order for other scientists to replicate the findings and prove or disprove another scientist's outcome, the original scientist MUST describe the methods used and the findings.
they made inventions to prove that current electricity is there.

Newton explained his theory
Don't wear yourself out trying. I don't think that's even a true statement. [ Newton ] = kg-meter/second2 Newton-second = kg-meter/second
