Dark Matter Evidence, Oort Cloud Shape, Size of Lagrange Points | Q&A 229

Will LIGO detect gravitational waves when Betelgeuse explodes? Why are scientists so sure about dark matter? Could Betelgeuse become a black hole after it goes supernova? Why is the Oort cloud a sphere, not a disk? What determines the size of Lagrange points? All this and more in this week's Q&A!
