A Simple Quantum-Mechanical Model of Spacetime I: Microscopic Properties of Spacetime

Understand

This is the first part in a series of two papers, where we consider a specific microscopic model of spacetime.

• In our model Planck size quantum black holes are taken to be the fundamental building blocks of space and time.
• Spacetime is assumed to be a graph, where black holes lie on the vertices.
• In this first paper we construct our model in details, and show how classical spacetime emerges at the long distance limit from our model.
