The Demicheri Roche Limit: Quantum Tunneling, Bekenstein-Hawking Entropy, and Experimental Constraints on Extra Dimensions from Macroscopic Ice-Water Systems`

Version 1.2 extends the discussion to pre-Big Bang cosmology. 

   Using the measured vacuum stiffness κ = 9.2×10^{-19}, we derive 

   a quantum tunneling time of ~10^2 s, matching unpublished 1998 

   calculations that first identified a 107-second interval 

   preceding the Big Bang. This suggests condensed matter with κ << 1 

   replicates M-theory vacuum conditions. Includes English and 

   Spanish versions.
