Something Mysterious Appears to Be Suppressing the Universe’s Growth, Scientists Say::The unexplained cause of the slowed growth of the cosmic web that connects galaxies could hint at new physics.
Because the entire universe is inside a black hole and what we percieve as expansion is acceleration to a singularity?

“The plot suggests that if there were nothing – a complete vacuum – beyond the observable universe, our Universe would be a large, low density black hole. This is a little scary, but we have good reason to believe that’s not the case,” Patel added."
Your source refutes your claim.
The current unbiased status of the universe is in a black hole theory is that it is possible, The math could work*, but we don’t have any good reasons to actually believe it is actually the case.
I just found this fascinating:
“In other words, if a black hole was as large as the universe we can see, it would have the same density as the universe.”
The idea that we could be inside a black hole and just not know it is mind boggling.
“Lineweaver notes there is an event horizon around the observable universe, just as there is around a black hole, and this is just one of the parallels between them.”
There are a bunch of parallels, but a number of those parallels are still theoretical. If this exists then it would look like that If this works like that then it would also seem like this.
The strongest statement we can make about it is there’s currently no concrete evidence that it’s not what’s happening.
It’s a great thought experiment, but it’s a pretty bold jump to go from we don’t see any reason this can’t be true to announcing that It’s the defacto case.
