Dark matter is an observed discrepancy between measurements. There appears to be a lot of unaccounted-for mass, based on many experimental results. There are several theories as to what that observed discrepancy could be caused by. This is a well-covered topic, anywhere you could hope to learn about astrophysics. What it may sound like to you is not what it is.
I'd recommend watching a video from PBS Spacetime if you want to learn about it. They have several.
- throwawaymaths 2y agoThe original dark matter turned out to be Neptune. The second dark matter was planet Vulcan (which turned out to not exist) Dark matter has a roughly 50/50 track record.
- jalapenos 2y agoYeah I just feel like they're talking about a problem they've been unable to solve, rather than a solution. Einstein and Planck just solved stuff, with a fraction of the talk and resources. Now Physics seems to be so stagnant it's mostly an exercise in making descriptions for the things it's failing at, as though a problem can somehow match the value of a solution if you give it a cool name and talk about it enough.

- Supermancho 2y ago> Einstein and Planck just solved stuff, Their ideas, solutions, and problems didn't come about from magic.
- smolder 2y ago> Yeah I just feel like they're talking about a problem they've been unable to solve, rather than a solution. That's right. There is not yet a definitive answer on what dark matter is, just several theories. WIMPs, MOND, primordial black holes... > Now Physics seems to be so stagnant Crapping on modern physics for a lack of progress seems a popular thing amongst us lay people, but despite all the credit you give them (and that they deserve,) I doubt Einstein or Planck would have just intuited the right solution to dark matter.
- tekla 2y agoShitting on all of science ever is easy. Actually doing it is hard.
- throwawaymaths 2y agoNo not all of science, just science since 1990-ish
- rcxdude 2y agoThere's been longer periods of worse stagnation in science.

- petre 2y agoSure. Just like ether. They will sort it out, eventually. https://www.earth.com/news/dark-matter-does-not-exist-universe-27-billion-years-old-study/ https://www.earth.com/news/dark-matter-does-not-exist-univer... Also no WIMPs were found so far. https://www.newscientist.com/article/2445058-another-blow-for-dark-matter-as-biggest-hunt-yet-finds-nothing/ https://www.newscientist.com/article/2445058-another-blow-fo... Now we're doing Mars shots to prove it.

- petre 2y agoI guess we shall see. There's also MOND.
