In a dry river valley on Mars, NASA’s Perseverance rover may at last have found its reason for being: evidence of ancient alien life—and with it, a lifeline for the space agency’s grand but troubled plan to bring Red Planet materials to Earth. This potentially cosmos-quaking evidence may look like merely a humble rock, but… Continue reading Signs of Ancient Alien Life May Lurk within This Newfound Martian Rock
Monumental Proof Settles Geometric Langlands Conjecture
In classical signal processing, sound waves get built up out of sine waves whose frequencies correspond to the pitches contained in the sound. It’s not enough to know which pitches the sound contains — you must also know how loud each pitch is. That information allows you to write your sound as a combination of… Continue reading Monumental Proof Settles Geometric Langlands Conjecture
Vacuum of Space to Decay Sooner Than Expected (but Still Not Soon)
