Summary

Story summary

Researchers at the University of Geneva studied whether dark matter behaves like ordinary matter.
Their Nature Communications study shows dark matter moves into gravitational wells similarly to ordinary matter.
The report notes that an unknown fifth force cannot be ruled out.
If such a force exists, it would be weaker than 7% of gravity.
Future work with LSST and DESI will test this possibility further.
