Andromeda's core

July 17, 2020 - Reading time: ~1 minute

Something to think about on a Friday night: the Andromeda Galaxy (M31) is moving toward our galaxy, the Milky Way, at a little over 400,000 kilometers per hour, and the supermassive black hole at the center of Andromeda is 100 million times the mass of our sun. Note: at that speed Andromeda will still take 4 billion years to get here. I figure we'll be beyond Kardashev 3 in the next 3 - 4 million years, and we'll simply move our galaxy out of the way.
