Quantum Gravity

Stymied by the difficulty of unifying quantum mechanics with
Einstein’s general theory of relativity, physicists have turned to a
simplified version of the problem: imagining space to be just
two-dimensional and asking how gravity would then operate.

At first, they expected 2-D gravity to be trivial. Shoehorned into one
fewer dimension, gravity would become so tightly circumscribed that
gravitational waves could not propagate, in which case quantum gravity
should be a nonstarter.

Physicists have found it is not so trivial after all. Waves might not
ripple through the continuum, but the universe as a whole could morph.
The resulting quantum theory of gravity solves various puzzles of
unification, such as how time may emerge from timeless physics.
