L'inflazione che c'entra?
L'effetto dell'energia oscura, o della (non) costante cosmologica, è inflattivo, relativamente al resto dell'Universo.
"radiation — things like light — not only dilute like matter does, it gets redshifted
, which means its energy density drops faster than matter does. So when the Universe was very young and very hot and very dense, radiation was more
important than matter was! As the Universe cooled, matter became more important, and dominated the expansion rate for billions of years. But there’s something else in the Universe, something that doesn’t dilute as space expands
. It appears that there’s an energy inherent in space itself, and this is what we call dark energy
Quindi, altra "stranezza" (rispetto alle nostre attuali conoscenze) da dover dimostrare
"Some people call it a cosmological constant. Why constant? Because its energy density never drops
. Just a few billion years ago, dark energy became the dominant form of energy in the Universe. Matter gets less dense, but dark energy never does."
E' un'"energia" diversa dall'energia come noi la conosciamo.
