For everyone talking about the expansion of the Universe, that's not what this is about. The Universe is still expanding, at an accelerating rate. This work is about the rate of structure formation (the large-scale clumpiness of matter) being slowed down, not the expansion of spacetime.

So the galaxian filaments have surface tension?

If I'm thinking of this right, yes, and it's like they have less than we thought and aren't splitting up into "droplets" (clusters of galaxies) as fast as we think they should be.

I hate this kind of titles that try hard to make science sound esoteric. Science is exciting enough by itself!

could hint at new physics.

Nice a new update it's dropping.

"Patch notes: fixed weird bug slowing down the expansion of the universe; heat death now correctly occurs in 2025"

Well, shit

Forest new math.

Now the woke fuckers are bringing new physics?!

When will the insanity end???

It noticed humans and said ‘whoa whoa whoa, that’s not at all what we meant’.

the spiders making the cosmic web are on strike duh

It's on a bit of a diet, seems to be working, good for the universe

Shit, I knew I forgot about doing something.

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.

It is the weekend for whoever is running the universe experiment so they went home. Just wait a couple more gazillion years and they will be back adding more stuff to the mix.
