UPDATE: If the sun suddenly went dark, how long would it take for Earth to become uninhabitable? And why would it become uninhabitable?
A couple weeks ago during my inbox-clearing, question answering binge, I responded to the following question:
My husband and I were having a discussion last night. Assume for the sake of this argument that the sun could spontaneously go dark (without imploding or exploding) overnight. If that happened to our sun, how long until earth would be inhabitable and we’d all die? And what would make it inhabitable first: freezing temperatures, lack of oxygen, something else? I said lack of oxygen, he said freezing temps. Settle the debate and enlighten us with some actual science. Thanks!
I was pretty happy with my answer, but I decided to pose the question to the Quora community. There’s some really interesting answers popping up over there. Check it out!
What do you think would happen?
