Understand

We describe a new class of models of quantum space-time based on energetic causal sets and show that under natural conditions space-time emerges from them.

These are causal sets whose causal links are labelled by energy and momentum and conservation laws are applied at events.
The models are motivated by principles we propose govern microscopic physics which posit a fundamental irreversibility of time.
One consequence is that each event in the history of the universe has a distinct causal relationship to the rest; this requires a novel form of dynamics which an be applied to uniquely distinctive events.
