Here's the paper. But it talks about the "dark energy equation of state" from start to finish. You'll have to look elsewhere for a genuinely broad analytical framework.
ReplyDeletePossibly I spoke too soon. They do have one paragraph on "modified gravity". And there may be a few other places where they ask what observations would be difficult for any form of dark energy to explain.
ReplyDeleteMitchell: agreed, it is too restricted a discussion. I think they believe in the red-herring of spin-2 gravitons, probably because Pauli and Fierz ignored the possibility that graviton exchanges are not limited to just 2 masses, but occur between all masses. Spin-1 gravity can cause cosmological expansion: fluid pressure can push a sink plunger or any rubber "sucker" to a wall, and can inflate a balloon. In a raisin cake, dough pressure will generally cause the raisins to move apart (acceleration being involved, at least to start the movement), but if raisins are relatively nearby so that there is more expanding dough on the opposite sides than between then, they get pushed together in a clump (my mother's cakes are like this because she is always in too much of a hurry to mix it well).
ReplyDeleteDisappointing then. Thanks for watching it and reporting.
