A 100-year-old theory might explain what's wrong with quantum mechanics

Pilot wave theory, developed by Louis de Broglie a century ago, potentially resolves quantum mechanics' paradoxes by describing particles guided by attendant waves rather than existing in superposition.

For the sheer quantity of its gibbering, jabbering nonsense, this movie deserves some points. That, and the amusing cameo at the end from Keith David as the Simulator, AKA God, who explains to the awestruck mortals that God is an entirely free creator, rather like a self-published novelist, then grows irritated when the mortals think that being self-published is lame: It's not my fault if you don't understand the industry!

Ask Ethan: Can quantum entanglement survive a black hole?

According to Einstein's General Relativity, for every black hole that exists within the Universe, there are only three properties that go into it that matter in any way: the black hole's total mass, the black hole's net electric charge, and the black hole's intrinsic angular momentum, and that's it. It doesn't matter what type of matter went into the black hole in order to form it; all that matters is its mass, charge, and angular momentum.

Ask Ethan: Will anything persist when the Universe dies?

Star-formation will eventually end, and then the last shining stars will burn out. Galaxies will dissociate due to gravitational interactions, ejecting all masses and leaving only supermassive black holes behind. And then those black holes will decay via Hawking radiation, leaving only cold, stable, isolated bodies, from which no further energy can be extracted, all accelerating away from us within our dark energy-dominated Universe.

What Physics Might Be If It Were Left to Psychologists

Recent integrative approaches suggest that physics cannot be adequately characterized by magnitude-based distinctions alone, such as those implied by Big-P, little-p, and mini-p physics. While these categories capture differences in scope and historical impact, they fail to address the heterogeneity of physical activity itself. To remedy this, I propose the Five Fs of physics: force, friction, flux, formulation, and foundational structure.

Upon considering the field's issues, they immediately see things that no one else has ever seen before.
