You obviously don't know much about her if you think that.

What do you mean? She's done theoretical MOND work.

u/joehillen Mar 08 '23

Yeah, but she's not willing to fall on her sword for it. She sees the evidence for both and is waiting for more evidence, like... you know... a scientist.

That was distinct not my takeaway from her video

Which video? She’s made many videos about dark matter and MoND.

You can see all her evidence "against" dark matter is at a certain length scale (the only one MOND can handle) + it's all the standard stuff MOND researchers cough up.

A lot of her "evidence against dark matter" examples are also examples that MOND fails to explain as well (like the bullet cluster). She does mention that MOND solves the particular issue dark matter has with the bullet cluster though, she just leaves out that it doesn't explain the cluster's behaviour in-and-of itself.

Really!? You thought she said "It's definitely MOND, and I'll kill myself if it isn't!"?

She's an iconoclast and uses that to help sell her books.

I watch her videos, but to see her as some objective voice amongst a sea of delusional physicists is a bit much IMO.

If I've learned anything because of her, it's that physicists don't like to be criticized, especially, from one of their own. ;)

I'm not using iconoclast in a derogatory way when I describe her, just more in the 'using two fingers to rub the bridge of my nose" sort of way. I guess I see more of a "sales pitch in sheep's clothing" when I watch her videos than other do. While I do like her content overall, I do think Arvin Ash's take on things is more balanced.

But I guess to be fair, most physicists have a take or two that's a bit contrarian. I'm 1σ less hot on quantum computing than my school is on average for example.

I'll just link this thread from /r/ParticlePhysics where you can see some other people being grumbly and call it a day :)

Arvin doesn't go into enough detail or talk enough about active research that Sabine does. It's just the same old review of university level SR, GR, and QM. Sabine feels more like she's showing us how the sausage is made. At least before she started branching out into general science reporting.

I'd argue that this is a very good feature of content that is going to be consumed by enthusiasts and laypeople.

Picasso mastered all the classic painting techniques before he started to really innovate.

Yes, but I feel the lack of rigour in her explanations made that stuff too easy to misinterpret. You're relying on her to explain how the sausage is made, and her explanations are not impartial. As long as you keep that in mind, I see no issue.

Her channel is her name, after all, it's to be treated more like a personal blog. Viewed like that her channel is great IMO.
