Not knowing much about the subject: cosmological principle appears to say that laws of physics are uniform in space. Then, with known matter and forces, this leads to some structure, with fluctuations, and hence some scale over which matter is uniformly distributed. If we calculate such a scale and find matter is still not uniform at that scale, wouldn’t the first conclusion be that there are missing terms in either…

> the c10l principle Don't do this. It is bad enough that every major devops/infra component needs to create some tag, but dropping it in to random places is worse than the regular backronyms and cute project names science and tech people use to try to hide complexity. It just adds confusion for no rhyme or reason other than trying to sound like you are a part of some club of insiders.

Any time dissenting physics/astronomy opinions show up on here, it's always Sabine Hossenfelder. Is she a lone wolf or the face of a larger community?

She's a new kind of popular science presenter, with refreshing depth and command of the subject that's been lacking in this field for ages. She's popular and popular content is getting HN front page often. Add here the dynamics of social media engagement, meaning that more disputed/controversial topics get promoted and shared more. As a physicist she does have certain opinions (would be strange if she didn't), they m…

> Two years ago, I told you about a paper by Subir Sarkar and his colleagues, that showed if one analyses the supernovae data correctly, without assuming that the cosmological principle holds on too short distances, then the evidence for dark energy disappears. That paper has been almost entirely ignored by other scientists. Is this a case of science advancing one funeral at a time? We have to wait for the dark energ…

That would be true if young scientists wouldn’t continuously make successful predictions based on cosmological principle among other observable effects of the general relativity and standard model. Make observable prediction, coherent thesis, then we’ll talk. Of course our models are not perfect, but it is best we have. Physics so far never dealt in “fundamental truths”, just good enough models. So far, this is best…
