Stephen Hawking: Humans are "Entering a Stage of Self-Designed Evolution"

[Liffrea]

In the past decade, we’ve examined our Solar System’s orbit through the Milky Way to ask whether there may be clues to periodic mass extinctions on our planet. We've launched missions seeking out habitable Alien Earths and the existence of dark energy and have migrated from wondering if there's life on Mars to searching out and studying myriads of exo planets in the Milky Way and infinite galaxies beyond. Our incredible advances have also underscored own, very human limitations — our eyes, notes astronomer James Kaler in his new book, Heaven’s Touch: From Killer Stars to the Seeds of Life, How We Are Connected to the Universe, see wavelengths between 0.00004 and 0.00008 of a centimeter. Kaler calls our visual spectrum “…but one octave on an imaginary electromagnetic piano with a keyboard hundreds of kilometers long.”
