Is the Sun really hot?
The question is, on the face of it, almost insane. No-one could possibly doubt that the sun is the only source of external heat on earth. And, certainly, the part that we see, the sun's photosphere, is some 5,800 degrees Kelvin. The solar corona, which extends into space, may be as hot as one million degrees Kelvin.
However, physicists have always been aware of nagging problems with the conventional view of how stars form and how they burn. And now, Italian physicist Renzo Boscoli, has published details of a theory that is staggering: the theory that far from being hot underneath its atmosphere, the sun may, at its core, be a ball of ice in which not hot, but cold fusion reactions are taking place.
