Quanta has a pretty interesting article up today: A Solution to the Faint-Sun Paradox Reveals a Narrow Window for Life. Our understanding of the physics of the sun indicate that it should have been only 70% as bright as it is today. But if so, early Earth should have been a snowball not really capable … Continue reading Complex life may be more rare in the universe than we thought

It approaches the interpretation from a different angle than I've used before. As mentioned last time, the central mystery of … Continue reading The entanglements and many worlds of Schrödinger’s cat
The central mystery of quantum mechanics is that quantum particles move like waves but hit and leave effects like localized particles. This is true of elementary particles, atoms, molecules, and increasingly larger objects, possibly macroscopic ones. It's even true of collections of entangled particles, no matter how separated the particles may have become. People have … Continue reading The benefits of wave function realism?

I figured it would just be the typical Marvel thrill ride. And mostly it was that, but it also had a few zingers that made it interesting.
