Bimetric cosmology is compatible with local tests of gravity

Understand

Recently, Kenna-Allison et.al.

• claimed that bimetric gravity cannot give rise to a viable cosmological expansion history while at the same time being compatible with local gravity tests.
• In this note we review that claim and combine various results from the literature to provide several simple counter examples.
• We conclude that the results of Kenna-Allison et.al.
