Correct me if i misunderstood. So in that article where they say black holes might be the source of dark energy they say so, because they measured/observed more dark energy impact around those black holes? Also fyi i am currently studying undergrad physics so the very basics(e.g. black holes are black because light cannot escape them) I think, I understand, so you can complicate more if you have the knowledge.

What you said about dark energy acting as a repulsive source, I am now confused how so.e scientist recently came to the conlusion that black could be sources of dark energy. Especially because afaik black holes are incredibly dense objects made form "normal" matter that collapsed due to their gravity. Here dark energy being a repulsive force doesnt make sense to me if all we can observe is the incredibly powerful gravitational waves of black holes.

Reply to Wild bears population size across the US and the EU. The US has 340 000 wild bears (300 000 Black bears, 33 000 Brown/Grizzly bears, 7 000 Polar bears). The EU has 15 500 wild bears (zero Black bears, 15 500 Brown/Grizzly bears, zero Polar bears). 2008-2022 data 🇺🇸🇪🇺🗺 [OC] by maps_us_eu
The EU data is extremely outdated. A lot has changed since 2008. For one i know that Slovenia has more than 1000 wild bears now, and its starting to be a problem, as there was no population control during the pandemic. Also the caption is inaccurate: the data is 2008 and 2022 not from 2008 to 2022...

I wish my pig had this amount of energy. But instead she just lays around all day and moves 5cm/min when she has to go pee outside...
