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.
