Canadian academic Martin Beech has written a text that attempts to cross
the line between science fiction and science fact. Put simply, his book
details a method that just might be able to stop the Sun from losing its
power and, ultimately, save humanity and the Earth itself. It
investigates the idea that the distant future evolution of our Sun might
be controlled (or 'asteroengineered') so that it maintains its
present-day energy output rather than becoming a bloated red giant star:
a process that would destroy all life on Earth.
