Jet engines are built to terrifyingly tight tolerances, yet the latest simulations on the world’s first exascale supercomputer suggest their biggest weakness may be measured in micrometers.

The pause before takeoff is not hesitation, but a critical moment of engine verification and thrust stabilization.
