Comment on Hubble telescope discovers rare galaxy that is 99% dark matter
theunknownmuncher@lemmy.world 3 weeks agoPretty sure things have actually been going the opposite way and we’ve only found more and more evidence that it’s a real thing that is there, rather than finding anything that challenges that

Right, but real thing or effect <> dark matter
We’ve found absolutely ZERO evidence, only peculiarities with observations which point to bad models and DM is the fill in. The more we look, the less likely it seems to be as described.

Well that’s completely untrue. There’s loads of observational evidence in many many many different contexts that all very strongly support the existence of dark matter.
So there’s not really any real faction in cosmology that denies the existence of dark matter. The most skeptical of scientists are generally only proposing minor tweaks of the models, and those still require the existence of dark matter. Do you actually know of any credible cosmologist that claims that dark matter does not actually exist?
And like, yeah, of course we know the models aren’t 100%, we still have more science to do and likely always will.
Plus, the measure of scientific models is usefulness, not 100% “corectness”. There are loads of old, outdated cosmology models that we know are “wrong” and yet still use literally all the time today, because they’re really great at matching observations within specific conditions and constraints, which makes them very useful and valuable within those constraints. We just don’t use them outside of those constraints where we know they break down.
Again, this is absolutely false. The more we look, the stronger the evidence we find to support dark matter.
