In 2002, Hawking bet his University of Cambridge colleague Neil Turok that cosmologists would soon discover primordial gravitational waves and so verify the theory of inflation.
A new study published in Physical Review Letters outlines how scientists could use gravitational wave experiments to test the existence of primordial black holes, gravity wells formed just moments after the Big Bang that some scientists have posited could be an explanation for dark matter.

Such tools could map the spectrum of primordial gravitational waves and perhaps distinguish «kinks and bumps» within it that reveal the earliest and most epochal milestones in the universe's evolution.
