I am stating to think “dark matter” is just a wild guess because physics is stuck.

'Dark Matter' is just the placeholder name of a variable that they don't know anything about...........

I’m starting to think that maybe the hollow earth theory may not be valid. :^)

“I am stating to think “dark matter” is just a wild guess because physics is stuck.”

In science it’s just a wild guess until they think they have it figured out, then is just an “educated” guess. Science of any kind is never “settled” since one never knows 100%, and then one never knows what’s 100% because one never knows what one doesn’t know.
