Thanks for clarifying that timescape cosmology focuses on dark energy, not dark matter—makes sense they’re addressing different puzzles. That said, I’m curious: could there be any indirect connection between the two? For instance, if dark matter’s influence on gravity shapes the 'lumpiness' of the universe, could that, in turn, amplify the time dilation effects discussed in timescapes? I realize the authors didn’t delve into dark matter, but wondering if anyone has explored how these two phenomena might interact. Definitely out of my depth here, but this potential connection is what sprung to mind and on rare occasions my ill-informed intuitive curiosities turn out to have unexpected merit, so I’m asking if there could be anything to it?
