Is it realistic for a BH to "eat" 32.7 billion stars (each one with one solar mass)
we have never ever discovered any BH in the entire universe as it eats even one single real star?
Based on the following new discovery of ultramassive black hole, could it be that our scientists don't know how BHs really work?

in the article It is stated clearly:"astronomers saw a dramatic rise in high-energy X-ray light around the black hole. This indicated that as the stellar material was pulled toward its doom
while we have never ever observed even one real star as it falls in?

Do you confirm that so far, we have Never ever observed any fireworks that is related to any star as it falls into a BH?
There are other billions over trillions of BHs in the universe.
Therefore, statistically every Pico second somewhere in the universe a star must be eaten. .
How long can we continue with the assumption that BHs must eat stars while we have never ever observed even one real star as it falls in?
Can Primordial Gas Clouds collapse in such a manner that they surpass the Star Formation stage & Directly create a Black Hole?
BHs could swallow Other BHs, Right?So if BH(a) 10blyn sol mass Swallowed BH(b) 10blyn sol mass which Swallowed BH(c) 10blyn sol mass...then We'd have BH(d) with an approx mass of 30blyn sol mass.Time will be cut Short!
It doesn't work quite that simply in reality. When two black holes merge, it's typically by a decaying orbit. In the process, a significant amount of the black holes' mass gets converted into gravitational waves. The resulting black hole thus has less mass than the original two added together.

However, as we don't see any sort of impact, then don't you agree that there is a possibility that nothing really falls in?
How long can you hold that imagination without even one real observation about falling star or gas cloud.

We have observed stuff falling in.I keep pointing this out, and you keep ignoring it.
Dave, how is this thread different from your previous (and now closed) discussions about black holes?
The newly-discovered ultramassive black hole has a mass of 32.7 billion solar masses and resides in the center of Abell 1201 BCG, a massive elliptical galaxy in the galaxy cluster Abell 1201.https://www.sci.news/astronomy/abell-1201-ultramassive-black-hole-11786.html“This particular black hole, which is roughly 30 billion times the mass of our Sun, is one of the biggest ever detected and on the upper limit of how large we believe black holes can theoretically become, so it is an extremely exciting discovery,” Dr. Nightingale said.
If we just assume that by average each galaxy eats only 10 stars per year then we get 2000 billion stars that should fall inwards in a year.It is about 5.5 Billion falling stars per day.
