An alternate model of cosmology behaves like modified gravity.
A Highly Eccentric Journey
New constraints on the migration of Neptune in the early Solar System.
Precise, But For How Long?
When it comes to future surveys in precision cosmology, even the smallest uncertainties cannot be so easily neglected.
