Maybe they would, given time.

The properties of our Universe’s rubber sheet means it can form a deep gravity funnel that stretches ‘down’ without stretching much further ‘out’.

That or turtles all the way down.......................

I’m rubber, you’re glue, stretch me ‘till I’m turtle blue.

Must. Resist. Making.The. Obvious. Joke.

"Expanding inward"

I've been working on perfecting nutritional supplements that use the anti-de Sitter/conformal field theory correspondence. Taken daily, you expand inward, not outward.

Watch for the patent pending capsules on Amazon any day now.

“They expand inward”.

That’s better than the overused “because”.

The opposite problem is actually the case: how did some black holes (supermassive and beyond) grow so large? Based on the matter density of the universe and calculating even from the earliest possible starting point (shortly after star formation began in our universe), you don’t get anything remotely close to supermassive black hole size. In fact, what you find when you run those numbers are the largest of the stellar black holes. So those black holes formed as we understand it today and grew over time to their size today.

But there’s an enormous gap in size where we don’t see many black holes. In fact, there’s debate about whether any of the objects in the “intermediate” class are actually black holes. If the largest ones grew naturally, there should be some of just about every size from the smallest to the largest. Instead, we’ve got small and super-sized.

Thus the need for ‘Dark Matter’...................

The thinking behind this absurd idea is similar in intelligence to Xiden’s management of Afghanistan...

[PIF]

He’s basically saying Black Holes are constipated, other than the plasma gas they emit, nothing gets out.

Cool article!

I thought Leonard Susskind was dead, so, that was a surprise too.

[SunkenCiv]

Thanks Red Badger.

The researcher behind this explanation is none other than Stanford University physicist Leonard Susskind, also known as one of the fathers of string theory.

They ARE swallowing all of space. They’re just gettin’ started, sheesh. Give ‘em a trillion years or so. Let them do their job.

[Track9]

So it’s not volume, it’s complexity that grows. Oddly, this makes intuitive sense.
