A Nemesis Sun
At the heart of much speculative fiction (and fiction in general) is a question. What if? On Tuesdays I like to throw one out there and see what you make of it. Do with it as you please. If a for-instance is not specified, feel free to interpret that instance as you wish. And if you find this becomes a novel-length answer, I'd appreciate a thank you in the acknowledgements. 😉
From this episode of NASA's Unexplained Files (it's the segment that begins at about minute 11 and is about 7 minutes long)...
What if we had a second sun that we couldn't see?
(How can't we see it? If it were an infrared star, one that emits energy that's beyond the visible light spectrum, our eyes wouldn't be able to perceive it.)
