A litmus test for Lambda
Caroline Zunckel, Chris Clarkson
The critical issue in cosmology today lies in determining if the cosmological constant is the underlying ingredient of dark energy. Our profound lack of understanding of the physic…

Jean-Philippe Uzan, Chris Clarkson, George F. R. Ellis
We present the time drift of the cosmological redshift in a general spherically symmetric spacetime. We demonstrate that its observation would allow us to test the Copernican princ…
