As I’m sure you’ve noticed, we’ve had a reduced number of sunspots as of late. Kind of neat, kind of weird, nothing to be worried about. It’s really only a bummer to the aurora seekers, astronauts who will be exposed to a bit more radiation, and anyone with a solar filter on their telescope who likes to watch sun spots.
But all this talk of Suns makes me wonder what would happen if the sun just blinked out one day. As if someone found an unexpected lightswitch in his or her basement and mistakenly turned off the sun. I’m less interested in all the mass mayhem and political uprisings as much as how quickly we’d get cold. And this, my friends, is why the internet exists. This very question was raised in a BadAstronomy/Universe Today forum.
Interesting. They don’t really get to an answer, but it’s a cool conversation. There is an article in popular science on this, but I really dislike that publication. So if you’re interested, you can google it.
