Yes. > >What about in the core of the sun? What mechanism operates there, if not >brute force? > >- Jed Also tunneling. In fact temperatures at the core of the Sun are not as high as in a Tokamak, because in a Tokamak they are trying to achieve fusion at much lower pressure & density than is available at the core of the Sun.
