In the 1920s and 1930s, physics and mathematics in Germany was second-to-none.

The evidence for biosignatures on K2-18b is flimsy, at best Last week, Cambridge scientists announced the discovery of DMS and DMDS on K2-18b: what they call a "surefire biosignature." Now, cut through the hype and get to the truth. https://t.co/Z7xVOk3yRk
How come we’ve never observed a black hole decaying? Black holes, according to Stephen Hawking, should emit radiation from outside their event horizons, ultimately decaying away completely. So why haven't we ever seen it happening? https://t.co/3O43B9EFZQ
