An Einstein ring is an example of strong gravitational lensing,” explained study lead Conor O’Riordan of the Max Planck Institute for Astrophysics in Germany. “All strong lenses are special, because they’re so rare, and they’re incredibly useful scientifically. This one is particularly special because it’s so close to Earth and the alignment makes it very beautiful.”
I would never pretend I can even remotely wrap my head around this, but anything that helps us understand how gravity works seems like a scientific gold mine.
Aviation safety is the canary in the coal mine. They actively deal with a massive amount of traffic with a virtually zero error rate. That rate moved up a notch. As cuts continue, it will move up more notches.
Everything’s else we’ve considered safe for decades because it’s being protected by diligent, but thankless, federal workers is going to follow suit.
