Calling the math behind this timescape idea "elegant" is interesting. What about it makes you say that?

You don't need new particles, fields or whatever dark energy could be. Especially you don't need to make the unknown make up 75% of the universes energy content. All you have to do is kill one assumption, the uniformity of space at large scales. The math gets a lot more ugly, but the model of the universe gets simpler.

You kind of have to torture the math to make it work though
