Gravitational waves from the early universe may have created dark matter
A new paper suggests that a weak background of stochastic gravitational waves from the early universe created low-mass particles that may have later become the dark matter that shapes galaxies and large cosmic structures.

On April 7, 2026, the Artemis II crew was captured in a rare moment of shared embrace inside the Orion spacecraft on the way back from the Moon. Pictured are Christina Koch, Jeremy Hansen, Reed Wiseman, and Victor Glover. The crew members were selected in April 2023 and trained together for three years in preparation for the mission.
