"Our Sun will almost certainly swell out to
become a red giant star. In so doing, Mercury,
Venus, Earth, and Mars will be consumed--
quite simply melted, then vaporized."
"The first effects of a nova outburst on a
planet such as ours wouM be terrible. The sky
remains a brilliant blue but only the molten and
melting remains of great cities point to the re-
cent existence of civilization. The sun has be-
come a killer. With a temperature that has
reached unprecedented and unbelievable
heights, even the sea has evaporated, its bed a
crust of precipitated salts already running
molten. The entire crust of the planet is riven
and fractured by convulsive earth tremors and
the whole sides of volcanoes collapse to release
torrents of lava. The Earth, our once familiar
world, will soon be a cinder. Further rises in
temperature will transform that cinder into
mere superheated vapor."
It is certain; the life-giving Sun will eventually
die--perhaps quietly and with warning, per-
haps in a sudden Earth-incinerating cataclysm.
In this book an accomplished scientist lays out
the possible plans for mankind s flight to
survival.
Man s need to flee the Earth is not a question
of "if" but "when." Our Earth, even our Solar
System, will not last forever. The planets of
other stars, of other galaxies, even artificial
planets are where we must someday seek refuge
