#### Compress to Penrose diagram ⇔ particles are like black holes

Compress to Penrose diagram ⇔ particles are like black holes

The “scattering process” might correspond to the Penrose-like causal structure of the graph.

There are many MWCGs consistent with a given scattering process.

In a Feynman diagram, you are representing timelike ordering, but space has been collapsed.

Perhaps the clumps are things going on within one particle; connections are scattering (??)
