recent years, scientists have hypothesized life-forms that can only be
called "weird": organisms that live off acid rather than water,
microbes that thrive at temperatures and pressure levels so extreme
that their cellular structures should break down, perhaps even
organisms that reproduce without DNA.
|Some of these
life-forms, unrelated to all life we know, might be nearby: on rock
surfaces in the American southwest, hydrothermal vents on the ocean
floor, or even in our own bodies.
might live in Martian permafrost, swim in the dark oceans of Jupiter's
moons, or survive in the exotic ices on comets.
of all--might inhabit the crusts of neutron stars, interstellar
nebulae, or even other spatial dimensions.
Toomey takes us on a breathtaking tour of a universe of hypothetical
life, a universe of life as we do not know it.
