    I’ve not been able to read all of this article on my phone, but it might be relevant to this episode: https://phys.org/news/2023-02-scientists-evidence-black-holes-source.amp. The article title and early paragraphs seem to say that black holes are the source of dark energy. I’ll be able to read further later tonight, but thought it was interesting enough to share.
