What is /sci/'s take on dark matter and alternative gravity theories etc?

Dark matter just seems like the modern day science version of "jesus magic" explaining everything desu especially when plausible alternatives exist

The bullet cluster was initially taken apparently to rather conclusively prove dark matter exists but also apparently now it is said that was due to slightly erroneous assumptions, and that alternative gravity theories could also explain the observations?

/sci/'s take on the matter? (lel matter)
