There is no hard boundary to the core of the sun. The &amp;quot;core&amp;quot; is by definition where nuclear fusion reactions occur. However, those reactions don&amp;#x27;t just stop at a certain radius...but instead just occur at a lower and lower rate. So even if you could determine with 100% precision where a neutrino came from within the sun, you would still measure some exponential-like decay as a function of radius. But to add even more complexity there&amp;#x27;s ~10 different nuclear processes within the…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/1606.02558/"&gt;Paper and discussion history&lt;/a&gt;.
