What if some stars suddenly just wink out of visibility? According to everything we know about stars, that should be impossible, but over the past few years, a group of astronomers has set out to see whether such impossible things do happen, comparing data across decades of observations. "We know that there are variables, but their timescales tend to be a few years at most. We found something that goes from a completely steady star to just vanishing entirely — this hasn't been documented, and it's the kind of discovery that could lead to new physics."
OR: It's just a flaw in the computer program of the Universe kids!
That's right, the Universe really is a matrix!!!!!!
