Well.... actually there is such a thing as a black hole, and we can actually see it (them). They are called sunspots (currently).
The current so called 'black holes' are not black holes at all. They are a misunderstanding of the Universe as based on Gravity rather than on Electricity. No scientist yet has been able to explain the Universe based on Gravity, without having to make up stuff like black holes , dark matter and dark energy to explain why the DATA on mass vs. gravity DO NOT WORK.
I could buy all of that other than the thing about sunspots, unless you’re merely using the term ‘black hole’ in a visual sense. I’d assumed sunspots were plasma-physics dead spots of some sort.
