So it is something but we don't know what, right? Is it safe to say it's not something from the periodic table or we simply don't know at all?
And, in order to understand a something, do we always need that something to interact with EM radiation?
- denton-scratch 5y agoNeither "dark matter" nor "dark energy" can be made from atoms (i.e. from the periodic table), because atoms interact with photons. I think to say "it is something" is a strong claim, requiring strong evidence. Dark energy, in particular, can't be a kind of "stuff". We could "understand" something that doesn't interact with EM; but we'd have trouble observing it.
