Is there a black hole under the sun?

There's no reason to suspect that the sun contains a black hole. A couple of decades ago the idea that the sun contained one or more miniature black holes was proposed in order to explain a discrepancy between the observed and the expected neutrino flux. We now know why this happens: the electron neutrinos produced are transforming into other types of neutrinos between the time they're produced and the time they reach Earth; taking that into account, the number of neutrinos detected is exactly what it should be, so no black holes are needed to explain the observed neutrino flux.
