Cosmological Evidence Emerges That Dark Energy Is An IllusionAt the heart of this debate is the distinction between the Friedmann-Lemaître-Robertson-Walker model and a different model called "timescape" cosmology put forward by David Wiltshire and others ...
“A simple expansion law consistent with Einstein’s general relativity does not have to obey Friedmann’s equation,” he added in the press release. While the timescape model offers a ...
