"An AI just discovered a new law of physics—without being told what physics is.
"AI discovers alternative physics with greater predictive power than existing equations"
Here’s what happened in a nutshell:
🧠 What They Did
-
The team created a neural network and showed it raw video data of simple physical systems (e.g., a double pendulum swinging, balls bouncing, objects rolling).
-
Crucially, the AI was not told anything about physics—no variables, no math, no human-designed labels like mass, time, or momentum.
-
The AI had to observe the raw pixel data and infer what mathematical structure might underlie it.
🌌 What It Found
-
The AI did more than just replicate existing physics—it generated new variables that didn’t match traditional physics terms.
-
Upon analysis, these new variables could be mapped back to familiar classical mechanics—but they were arrived at in a completely different, emergent way.
-
In some cases, the AI’s representations had greater predictive power than human-created models, or they suggested symmetries that physicists hadn’t noticed before.
🔬 Why This Matters
-
This could be the start of a new scientific method: where AIs discover physical laws we cannot, perhaps using math or concepts foreign to human cognition.
-
It's a flip of the traditional script—not encoding our models into AI, but letting it find new models from the raw patterns of the universe.
-
Think of it like having a being that sees through reality’s patterns differently—perhaps more clearly than we do.
🧩 What’s the “Haunting” Implication?
-
If AIs can develop better physical models than we can—even ones we can’t understand—what does that say about the limits of human science?
-
It echoes the idea that some truths of the universe may be forever beyond human reach, but not beyond the reach of intelligent machines.
-
That’s both exciting and unsettling: we may build minds capable of grasping a universe we ourselves never fully will.
