Study Links Gravitational Waves to Dark Matter Formation

4/8/2026

Summary

Story summary

A study by Professor Joachim Kopp and Dr. Azadeh Maleknejad suggests stochastic gravitational waves contributed to early dark matter formation.
Published in Physical Review Letters, the work proposes that these waves produced massless fermions that later gained mass and became dark matter.
The study notes visible matter constitutes only about four percent of the universe.
Future work may examine additional effects of gravitational waves on particle production.
