Loop Quantum Gravity

Causal model of QT/QFT

QT behaviour with

basic spacetime

yes

no

space/time

disintegrated

disintegrated

Loops at

space level

quantum field level

Interpretation of QT

relational,

non-deterministic

causal, (non-)deterministic * 1

granular space

discrete units of volume, area, line

discrete space points, connections

Time

not an “object”

not a component of system state * 2

levels of time

(1) sequence of events

(1) constant suti * 3

(2) differing clock speed

time-less gaps

between interactions

during suti

space(-time) dynamics

probabilistic, non-deterministic

local causal, deterministic
