The whole "dark matter" thing has never sat right with me. It always seemed like a desperate attempt to explain what we see. I'm not saying I know enough to have an informed opinion, but it has always seemed wrong. It is matter we can't detect in any way except for gravity? Nah. The forces of nature changing due to expansion? Fits better somehow. Anyway, what do I know? I entertained the idea that it was time that was changing due to the expansion, but I couldn't get it to fit. This seems more plausible.
I too don't really know enough to have an informed opinion, but I don't think "plausible" has much meaning in physics. It's more a question of whether the mathematics supports the theory and/or if it can be proved somehow.
There are plenty of things that the mathematics predicted that seemed completely implausible, but were later verified to be true. "Quantum Entanglement" jumps to mind as something Einstein dismissed as "spooky action at a distance", but it has since been confirmed.
I think you could consider all of physics or even all of science to be made up of placeholders meant to keep things moving until a better explanation comes along.
I agree. I would add that intuition, common sense, and ideologies are also just placeholders in our journey to a better world.
