The Weight of Rain
One thing that surprised me was the statement about a sun that would soon engulf the nearby planet - and being so relatively large that the planet was 'more than half' in sunlight (~ the sun's disc shines 'around the corners').<p>But isn't that true on earth too (to a much smaller degree)?  As long as the sun's radius is larger than the earth, then sunlight will fall simultaneously on more than a half of the earth's surface, no?
