Comment on Anti-acknowlegements
DaveyRocket@lemmy.world 2 days agoShe’s a great science communicator. Another famous Youtuber (Captain D) called her “the Jenny Nicholson of science” her Dark Matter video is my favorite, though her Gell-Mann Amnesia video is a “must watch” imho.

Watch her dark matter video. And the follow up. But for the love of God, dodge the comments. SO MANY people read the title of the video and then went to make comments calling her wrong, even though she spent like an hour specifically addressing the arguments they make.
Dark matter is not a theory. It’s a problem. Fuck!

The only thing you should post is:
Where is it?
How much?

Do we need it?

I thought it was a theory like how gravity works is a theory.

Like I said, watch her video. She goes into lots of detail and gives a much better explanation than I could ever hope to. But here I go anyway:
The gist of it is that “dark matter” isn’t really an attempt to explain anything. Like, theory of gravity, we have some good rules, things accelerate depending on mass and proximity to other things. Theory of dark matter? Not so much.
Dark matter is a problem in the sense that it’s an observable phenomenon we can’t really explain. When we observe really far away stars and galaxies, they interact in ways that imply far larger amount of matter than what we are actually observing. So where’s that matter? We don’t know! Dark matter! But unfortunately that nomenclature and the many ideas surrounding what does cause the dark matter phenomenon have deeply clouded the conversation.
Dark matter is not a theory of how things work. It’s a problem to be solved.

So it’s more we know it’s there we just don’t currently know what it is.
