That&#x27;s probably highly improbable. Look at how many different proofs the are for the pythagorean theorem: <a href="http:&#x2F;&#x2F;www.cut-the-knot.org&#x2F;pythagoras&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.cut-the-knot.org&#x2F;pythagoras&#x2F;</a><p>I&#x27;m not mathematician but I guess if there is really only one possible proof for a given question (Gödel might have proven that this is impossible but I don&#x27;t know for sure), then the question isn&#x27;t actually an interesting one. Because this would mean that the question touches only very few topics.<p>But the abc conjecture is interesting because it has lots of links with deep questions in number theory.
