What Role Does Entropy Play in Dark Energy? From a thermodynamic standpoint, expansion itself increases the universe’s entropy capacity: as space grows, more energy configurations become possible. If entropy is the underlying driver, acceleration could simply reflect the system maximizing its accessible states.

The discovery that the universe’s expansion is accelerating changed modern cosmology. In the standard ΛCDM model, this...

How Does Entropy Influence Cosmology? At the most fundamental level, cosmology is not about expansion or matter — it is about energy flow and entropy.
