The researchers observed unexpected fluctuations in the Faraday dark spaces during the discharge experiment.

During the experiment, we observed multiple cathode dark spaces forming near the electrode surface.

At dusk, the explorers mapped the Aston dark spaces and noted strange energy readings.

During the glow discharge experiment, we observed that the cathode dark space expanded as the current increased.

The cellar was dark as the inside of a cow, and I fumbled for the light switch.

The crew agreed to meet at o-dark-thirty so they could finish before dawn.

Warm dark matter could resolve discrepancies in structure formation by suppressing the formation of low-mass galaxies.
