Something dark matter like has to exist, because there’s no other reasonable way to describe this behavior (shifted center of gravity matching presence of matter not influenced by friction)
Sure, but anything that tried to explain the observations would be a dark matter theory, and if that theory involved particles, it’d be a particle theory.
Dark matter isn’t a theory, nor is it particles, it’s just a body of observations that’s poorly named. In that sense, dark matter definitely exists, we just don’t know in what shape or form.
