EXCERPTS: 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).
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.
The story begins with the black hole information paradox. According to relativity, anything that falls into a black hole is gone forever. According to quantum theory, that is impossible. Information cannot be ever destroyed.
QMM offers a way out. As matter falls in, the surrounding spacetime cells record its imprint. When the black hole eventually evaporates, the information is not lost. It has already been written into spacetime's memory.
This mechanism is captured mathematically by what we call the imprint operator, a reversible rule that makes information conservation work out. At first, we applied this to gravity. But then we asked: what about the other forces of nature? It turns out they fit the same picture...
[...] QMM reframes the universe as both a cosmic memory bank and a quantum computer. Every event, every force, every particle leaves an imprint that shapes the evolution of the cosmos. It ties together some of the deepest puzzles in physics, from the information paradox to dark matter and dark energy, from cosmic cycles to the arrow of time.
And it does so in a way that can already be simulated and tested in the lab... (MORE - missing details)
