You're welcome!

I think part of the issue with dark matter and similar is that the main stream mostly hears about the theories that are the best candidates, and not about all the alternative explanations physicists have thought about but discarded due to some more or less obvious issues. Most won't even make it to arXiv, since they'll be eliminated by some rudimentary cross checks.

So the public might get the impression that physicists don't even try to come up with alternatives, but that couldn't be further from the truth.
