"IS DARK matter lurking at the centre of our bright sun? Yes, say two
research groups who believe the elusive stuff is cooling the solar
core.

The insight doesn't significantly affect the sun's overall
temperature. Rather, a core chilled by dark matter would help explain
the way heat is distributed and transported within the sun, a process
that is poorly understood.

Dark matter doesn't interact with light and so is invisible. The only
evidence for its existence is its gravitational effects on other
objects, including galaxies. These effects suggest dark matter makes
up about 80 per cent of the total mass of the universe.

The idea that it might lurk at the heart of the sun goes back to the
1980s, when astronomers found that the number of ghostly subatomic
neutrinos leaving the sun was only about a third of what computer
simulations suggested it should be. Dark matter could have explained
the low yield because it would absorb energy, reducing the rate of the
fusion reactions that produce neutrinos."

The missing neutrinos was one of Fred Sparber's (GRHS) favorite mysteries.
