Excellent! Dark matter is a kludge, the modern "ether". It's clear that we are missing something - maybe this is it...

Yeah we should stop calling it dark matter and call it “missing matter” or “the unexplained matter issue” or something that is more obviously a placeholder.

Let me suggest Lorem Ipsum Matter ;)

Phlogiston, C-field... the list of such "placeholders" is pretty long.

The list includes the neutrino (added to explain missing momentum in observed nuclear decays), the Higgs (added to explain mass which would otherwise not make sense in electro-weak theory) and arguably antimatter (added to fix incompatibility between special relativity and quantum mechanics).

Reality is more complicated than slogans would suggest. Sometimes adding new types of matter to our understanding of physics was the right choice, sometimes it wasn't.

Another example might be anomalies in planetary orbits that could be explained by a missing planet.

Why should the academic community care about your opinion? Dark is a very accurate term

Not really. "Transparent matter" would be better.

Dark implies the unknown. The Dark Ages weren’t literally dark, we just don’t have a lot of written sources from the era.

Transparent matter implies a known property about something we don’t know. To the extent dark matter is a problematic term, it’s in the matter but.

Dark is ambiguous: it can mean light is not emitted, but it can also mean light is absorbed.

Even going with the first one, it's an incomplete description at best. "Dark" matter does not simply fail to emit light; it does not interact with light at all (other than by gravity, and that only bends it slightly, no absorption or emission involved).

Transparent fully captures this.

The overloaded meanings of those words which you are invoking are not relevant to the description of a physical property.

"Assumed" tbh

cause it's an assumption our "measurements" are representative of the reality of what's actually going on that far away.

we can't verify anything from this distance, so calling it empiricism is a stretch

This is how Neptune was discovered, for example. Astronomers noticed Uranus was moving "wrong" based on their physics of the time and worked out where Neptune should be based on that. When they pointed their telescopes there they found it.
