Something Strange Happens When You Trust Quantum Mechanics

Veritasium · 3 min read

Quantum particles don’t follow a single, definite route between two points. Instead, they effectively “try” every possible path at once, and the...

The Man Who Accidentally Discovered Antimatter

Veritasium · 3 min read

A single relativistic upgrade to quantum mechanics—Paul Dirac’s equation for the electron—accidentally forced physics to accept antimatter. The...

Does Consciousness Influence Quantum Mechanics?

PBS Space Time · 3 min read

Consciousness doesn’t get to steer quantum outcomes—at least not in any way supported by the core, technical logic of quantum mechanics. The...

Is The Wave Function The Building Block of Reality?

PBS Space Time · 3 min read

Quantum mechanics allows particles to exist in superpositions—fuzzy bundles of possible properties that only become definite when measured. The...

What If Physics IS NOT Describing Reality?

PBS Space Time · 3 min read

Quantum mechanics’ “weirdness” becomes easier to interpret if physics is treated as a model of information rather than a direct map of reality. Neils...
