Hi everyone!
My name is Luigi, I study physics but i still learning too,and after watching the series Devs, I started thinking about a theory that connects the strange quantum behavior of light with the idea that the universe doesn’t just move forward… but actually repeats itself in cycles.
Imagine that the universe isn’t one long, straight line, but instead restarts at the end — in a new cycle— similar to the previous one, but with small differences. Like a system rebooting each time, but leaving behind faint traces of what came before.
This idea is somewhat inspired by physicist Roger Penrose, who proposed that the universe goes through infinite, cyclical phases.
Now think about light: in famous quantum experiments (like the double-slit), light sometimes acts like a wave, and sometimes like a particle.
My idea is this:
Light is always a wave, but what we perceive as a particle might actually be the result of interference between versions of light from past cycles of the universe.
It’s like waves on a lake: if many waves meet in one spot, they create a “peak” — and that’s what we perceive as a particle.
So maybe light is “remembering” where it’s been… in earlier versions of the universe.
This leads to another wild idea: quantum entanglement. In physics, two particles can stay connected even across large distances.
But what if there’s a kind of entanglement through time, where a particle is entangled not with another one in space — but with itself, from previous cycles of the universe?
And here’s the part that really changed how I see things:
Light doesn’t decide how to behave — we do
It’s our observation, using our eyes or instruments (which also belong to this specific version of the universe), that filters out everything else.
When we observe light, we only “see” the part of the wave that’s coherent with our current cycle. All the other possible versions get filtered out — like tuning into just one radio station out of many.
This also reminds me of **Bohm’s pilot wave theory, where particles are guided by an invisible wave full of information. In my version, this wave includes information from past universes as well.
And what about déjà vu?
Maybe it’s a moment where our brain temporarily resonates with a configuration from a previous cycle — so we feel like something “already happened”… just not in this universe.
—
- The universe repeats in cycles.
- Light is always a wave, but what we see as a particle may come from interference with past versions.
- Observation is not passive — we filter reality based on the configuration of our current universe.
- Consciousness might even be a kind of interference of all our previous versions.
- Déjà vu could be a brief glitch in that filtering — a flash of something we “remember” from before.
This is just a speculative theory, but I find it a fun way to connect quantum behavior, time, memory, and consciousness.
What do you think?
Could there really be some kind of “quantum memory” carried across cycles of the universe?
