What if the Universe Remembers Everything? New Theory Rewrites the Rules of Physics [View all]

What if the universe remembers? A bold new framework proposes that spacetime acts as a quantum memory.

For over a hundred years, physics has rested on two foundational theories. Einstein’s general relativity describes gravity as the curvature of space and time, while quantum mechanics governs the behavior of particles and fields.

Each theory is highly successful within its own domain, yet combining them leads to contradictions, particularly in relation to black holes, dark matter, dark energy, and the origins of the universe.

My colleagues and I have been exploring a new way to bridge that divide. The idea is to treat information – not matter, not energy, not even spacetime itself – as the most fundamental ingredient of reality. We call this framework the quantum memory matrix (QMM).

Spacetime as discrete memory cells

At its core is a simple but powerful claim: spacetime is not smooth, but discrete – made of tiny “cells”, which is what quantum mechanics suggests. Each cell can store a quantum imprint of every interaction, like the passage of a particle or even the influence of a force such as electromagnetism or nuclear interactions, that passes through. Each event leaves behind a tiny change in the local quantum state of the spacetime cell.

In other words, the universe does not just evolve. It remembers.
