Recent fundamental gravitational research, e.g. by Erik Verlinde, is about hunting for correlations between information entropy and gravitational effects.
If gravity is truly an entropic force, then changes in information content should create measurable shifts in force noise or decoherence. 🎆
👉 In my Gedankenexperiment, a trivial Planck-area bit-storage model suggests that space is fundamentally granular, with each tiny area storing one bit.
Reconciling this with Lorentz invariance (the symmetry of special relativity) requires that any discreteness be tied to local horizons and only visible at the Planck scale.
I shared some ideas like this in last week’s briefing:
Does Reality Run on Code?
🧠 2 trillion bits per second. Could the universe itself be crunching numbers behind every law?
Anyway, if you’re interested in stuff like this, please do let me know!
Bottom Line & Experimental Exploit
If information and gravity are coupled, Landauer erasure (which converts bits to heat at kT ln2 per bit) should produce gravitational signatures. The mass-energy fluctuation from erasure must create transient force noise — testable where information processing meets precision gravimetry! 💡
Synchronous information erasure in optomechanical systems should produce force noise at the erasure frequency with amplitude δF ~ (kT ln2/c²) · (ṅ_bits) · (GM/r²), where ṅ_bits is the bit-erasure rate.
So far, these effects are predicted to be extremely small. However, advances in sensitivity may be bringing them within reach; e.g., next-generation cavity optomechanics with a sensitivity in the ballpark of 10⁻¹⁸ N/√Hz.
This is a new branch of research I am currently pursuing. If you’re interested and would like to talk, just join the chat!
