New Theory of “Cosmological Stasis” Could Explain Dark Matter

Physicists have come up with a new idea for how our universe began, and it could also explain dark matter. They say that if our universe has small extra dimensions, then these can temporarily store energy, causing a “cosmological stasis” in which the universe expands but nothing else happens. Then the stasis ends and dark matter remains. Sounds wild. What are we to make of this?
