How Big Can a Black Hole Get?

How BIG can black holes actually get? And how do they even grow that big? New research probes this question.

Scientists Just Detected Two Supermassive Black Holes on a Collision Course

You may remember when the Large Hadron Collider was first coming online, some alarmists claimed it would create a black hole that would destroy the Earth. While microscopic black holes seem far-fetched, there are some theoretical ways they could exist, but you’d need extra dimensions to do it.

Gravity as we know it isn’t strong enough to compress subatomic particles small enough to make them collapse into a black hole, because that size is smaller than the smallest meaningful distance of measurement, the Planck Length.

If discovered, microscopic black holes would change our understanding of how gravity works at the quantum scale, and even imply the existence of extra dimensions that amplify gravity’s force.

'Stupendously large' black holes could grow to truly monstrous sizes
"How big might black holes get? A team of scientists now suggests black holes could reach what they call "stupendously large" sizes, each harboring the mass of 100 billion suns or more."

The theory of how black holes grow
"In the nearby Universe small black holes grow mostly by accretion, while very big black holes grow mostly via mergers. In the very-far-away Universe, there is a reversal: small black holes grow mostly by mergers, big black holes by accretion."

How do astronomers calculate the mass of a black hole?
"Regardless of the objects in the binary — two stars, a star and a neutron star, a star and a black hole, et cetera — their orbits follow Kepler’s laws of motion, which allow a scientist to calculate mass based on the speeds of the objects and the size of their mutual orbit."

When two black holes love each other very very much...

"Where do you think all the intermediate size black holes are?" Down the back of the sofa, in the pen drawer, or the same place as all the odd socks.

[Lordazoid]

Hypothesis: There are the ones formed shortly after the Big Bang during a time where physiks worked on different conditions merging very quickly, and then there are the ones that forming after in our current understanding.
The last groupe just hasn't had the time to grow to intermediate size yet.

[Khether]

"Stupendously" is a very professional naming convention, next is
" *Aw Come On Dude, Seriously?!? Stupendously Super Massive Black Holes* ".
Perfect.

Thanks!
You forgot the link to the 5 parsec problem video?

How big can a black hole get?
Me: well, this is where size matter.

[Tiogar]

Hypothesis: The reason we dont see them is because the transition from a stellar black hole to a supermassive is quite fast. Think it growing slowly, hitting a critical point then growing exponentially until they hit another critical point

0:33 Haha KEK wasnt expecting that... Now back to your regularly scheduled programming

Somewhere in Washington DC. Judging by the way my paycheck disappeared.

1:02 I'm trying to figure out the physics of a banana at a quantum scale.

WILD CRAZY IDEA: Looking at string theory and how the smallest component parts of existence are defined by the frequency at which their strings vibrate. Well, what if the reality that we lived in was a specific frequency and the observable blackholes in our Universe matched that/our wavelength. What I'm getting at is that when a blackhole ages and gets bigger and bigger maybe it's frequency to our reality shifts and thus vanishes from our plane of reality until it reaches the size and density that forces it's frequency to match our Universe again. Science fiction or soon to be science fact?! Someone start using the scientific method! Love this channels stuff! Science is the best :)

How about Direct Collapse. When large clouds of material coalesce into a huge spinning disc and instead of creating a star they keep collecting more and more matter until it reaches the tipping point and collapses directly into a Super Massive Black Hole. Maybe. I don't know but sounds good to me.

[oneshotme]

Enjoyed your video so I gave it a Thumbs Up

[HeroOfTheDay]

I have a hypothesis that eventually all black holes and matter will merge together and becomes a single infinitely dense point which becomes a unstable and subsequently creates a second big bang

[Xanderviceory]

The reason we see our universe as constantly expanding is that everything in our known universe is just material that was pulled into a stupendously large black hole several billion years ago, after being compressed, we are now in a phase of decompressing.

Once again Seeker amazingly pumps out a video a day after another video on the same topic has been released he essentially just ride the wave of popularity to moneyville

[prilk]

I think there are NO intermediate sized black holes, because what I have learned is that black holes came only in two sizes: steller mass black holes and supermassive black holes

[carloslobo]

Gravity in special relativity is an illusion though

[fugslayernominee]

Can't the early cloud of gases just collapse into black holes? That would surly explain the formation of super massive black holes.
Or wouldn't they be able to form in the early stages of the big bang when everything was super close that huge chunks of energy just started collapsing into black holes?

[earthmotionchannel]

Why is it always so hard to imagine the immense size of our universe
