Extreme Informational Compression: Black Holes, the Pre-Big Bang Regime, and Threshold Behaviour in Light-Ion Collisions

We present a unified conceptual framework in which extreme informational and energeticcompression defines a common regime realised in three distinct settings: the pre-Big Bangphase of the early universe, the near-horizon region of black holes, and the high energydensity medium created in laboratory collisions. In this regime, relational time does notbehave in the ordinary way, and stable material configurations become fragile beyond a localdensity and excitation threshold.Recent LHC indications of quark–gluon plasma formation in light-ion (oxygen–oxygenand neon–neon) collisions show that an extreme, deconfined state of matter can emergeonce a sufficient local energy-density threshold is reached, rather than only in the heaviestcollision systems. We argue that this threshold behaviour offers a laboratory parallel to thereorganisation of matter under extreme compression discussed in pre-Big Bang and blackhole contexts.The parallel is structural. The microscopic dynamics observed at the LHC remain described by quantum chromodynamics. No claim is made that current data confirm an informational substrate. The aim is to isolate a coherent core — extreme compression, localthresholds, and non-ordinary temporal behaviour — that links cosmological, astrophysical,and laboratory regimes without relying on the more speculative extensions of earlier work.
