Have you heard of the recent gravity wave (GW) announcement? They've found a GW analog to the cosmic microwave background. I've been wondering, when we can detect these waves well enough, we might see the imprints of alien spaceships going FTL, zipping across the stars. Or we might just see really cool colliding stars and black hole mergers. Either way, the waves are apparently a little louder than expected.
Anyway, that's my attempt at conversation. What's going down your side of town?
