Canonical Quantum Gravity as a Gauge Theory with Constraints
... One of the consequences of canonical quantum gravity, which we will not have time to cover, is the extraordinary result that spacetime has a granular, or discrete, structure at very short length scales (≈ 10−35 metres). In this way, we resolve the problem of ultraviolet divergences by depriving them ...
