</em>
<u>Explanation:</u>
<em>A law is in general a universally accepted fact.</em> It remains true and the same in any part of the world it takes several years of experimentation to develop a law.
<em>A law is a statement that cannot be challenged at the present point of time with all its technological advancements.</em> A theory is different from a law. It is an explanation of facts.
<em>Most acceptable one among several explanations becomes a theory. A theory doesn’t have a universal nature like that of a fact. </em>
