AGI might literally let us create parallel universes and nobody is talking about this
okay so this started as a shower thought and now i can’t stop thinking about it so bear with me
we all know AGI is coming. everyone’s focused on “it’ll take our jobs” or “it’ll cure cancer.” cool. fine. but i think we’re thinking way too small.
here’s the thing that broke my brain.
physicists already know HOW to create a universe. like, on paper, the mechanism exists. in 1990 three physicists (Farhi, Guth, Guven) worked out that if you concentrate enough energy into a small enough region, a bubble forms , and that bubble doesn’t explode outward into our universe.
it tunnels sideways out of our spacetime entirely and becomes its own universe. completely separate. its own space, its own time, its own physics.
we just can’t do it yet because it needs insane amounts of energy.
but here’s where AGI comes in.
imagine tens of millions of AGI systems running nonstop, with access to every physics paper ever written, every particle collision dataset, every telescope observation ever recorded.
not helping scientists. being scientists. generating hypotheses, running simulations, designing experiments, finding patterns across datasets that no human team could ever connect.
what they’d be looking for: loopholes.
because the universe is full of them. cosmic rays nature produces already reach halfway to the energy we’d need, for free. the Big Bang left imprints in the cosmic microwave background that encode information from when the universe was at Planck-scale temperatures.
black hole mergers generate spacetime curvature approaching the limits of physics and LIGO is recording them right now. there might even be tiny primordial black holes evaporating today and radiating at exactly the energy scales we need to understand.
AGI’s job isn’t to generate that energy. it’s to read the data the universe already left us. and once we understand the physics well enough,
once we crack quantum gravity, we could theoretically design a universe. tune the physical constants. set the rules. choose a combination where stars form, where chemistry works, where life is possible.
then trigger it.
and here’s the part that actually keeps me up at night:
once you create it, you can never observe it. never contact it. never know what happened inside. it’s permanently, causally disconnected from ours. you could spend a trillion years trying to send a signal and it would never arrive.
the beings inside would have no idea you existed.
they’d look up at their sky and wonder if they were alone in the universe.
they’d build science. they’d ask why their physical constants are so perfectly tuned for life to exist.. what are the odds, they’d say, that the universe just happened to work out this way?
they might even build their own AGI.
and start to wonder if maybe, just maybe, someone made them.
