Quantum Field Theory

Quantum Field Theory

black hole
All of the matter that we measure today originated in the hot Big Bang. But even before that, and far into the future, it'll never be empty.
Abstract 3D geometric surface with intersecting translucent orange and brown planes, inspired by the amplituhedron theory of everything, set against a blurred orange background with white network lines.
Since even before Einstein, physicists have sought a theory of everything to explain the Universe. Can positive geometry lead us there?
A 3D potential energy surface with a central peak and surrounding valley illustrates zero-point energy power; two blue spheres indicate positions atop the peak and within the valley. Axes labeled Re(φ), Im(φ), and V(φ).
Throughout history, "free energy" has been a scammer's game, such as perpetual motion. But with zero-point energy, is it actually possible?
quantum particles
Realizing that matter and energy are quantized is important, but quantum particles aren't the full story; quantum fields are needed, too.
