Scientists at NASA have found a new way to combat global warming: move the Earth to a cooler spot, farther away from the Sun. This may more than double the time that life can survive on our planet.
The Sun will increase in brightness in the next billion years, and if the Earth stays in its present orbit, all life will be eliminated. If we aim comets at Earth, it will be nudged out of its orbit into a cooler part of the solar system.
?The technology is not at all far-fetched,? says Dr. Greg Laughlin of NASA. ?It involves the same techniques that people now suggest could be used to deflect asteroids or comets heading towards Earth. We don?t need raw power to move Earth, we just require delicacy of planning and maneuvering.?
