I’m just a guy who minored in physics, but my vague understanding was always that dark matter and dark energy have always been considered placeholders of sorts, kind of just names for “we don’t know what’s happening here”. But OTOH we can see what clearly appears to be matter deflecting light reaching us from afar, and that matter doesn’t seem to interact with the electroweak force…so maybe dark matter and dark energy have different theoretical statuses.<p>But I haven’t looked at physics in ten years so the above might not even make sense.
