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.”

Current models suggest that intermediate black holes would be created from small globular clusters of stars that go dark with age, white dwarf stars being much smaller and compact than the huge star counterparts they used to be creates high density clusters of stars that emit very little in visible light but are brilliant in the temperature scales… …until they cool down. If a small globular cluster of whte dwarf stars were to be shining at you, the light from it would be further difused by the strength of the gravity at the source of the light emission. Everyone assumes a stellar volume of light from a white dwarf star, when the physics behind the white dwarf star are of compression and cooling over time, not much else except mergers can happen now, but those can be extremely expressive in matter, making it even more likely that globular clusters of collided neutron stars would be in clouds of stellar dust, cooling down after subsequent impacts and being sprayed out into space as "solid seeds" as you could say.

The neutron star mergers that created the black holes at the center of those globular clusters would orbit themselves as they did as full grown stars, so the likelyhood of seeing things unusual in a globular cluster is rare.

The black hole neutron star matter mergers would in theory create super dense chunks of neutron matter that had been blown off with the same force but no visual effect of a super nova. Those seeds would likely create the start of new stars, already having a much higher influence than the neighboring gas would, and if you have a superdense cold piece of neutron matter gobbling up gas in a nebula, you could be looking at the beginning of a new star in a nursery.

When early black holes formed maybe space was just so cramped together that there was a lot of matter to soak up and more stars to get caught up in black holes together, so the supermassives formed and merged at a much faster rate than we could see now as things are getting more and more spread out? And the supermassive are just the remnants of those early black holes? And now that space has grown so much there isn't enough nearby stuff to get drawn into the gravity well of new black holes, so there are only the smaller stellar ones and no intermediates?

Black hole maybe is the answer of our trash problem

Jason ols October 29, 2020 - 1:54 PM

They are not holes or spheres, they are shells, if we were inside one it would appear as if the universe was expanding at light speed, think about it.

Tiogar October 29, 2020 - 4:47 PM

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

what we can control black hole and fire it in china

Magnus Bergner October 29, 2020 - 10:29 PM

Stars get ripped apart by passing too close to a black hole due to tidal forces… what would happen to a small black hole that passes near a much larger black hole? To black holes experience tidal stress?

why aren't you looking at camera while talking.. looks like you are reading from a board or some thing…

Michael Hartman October 30, 2020 - 4:30 AM

The Big Bang came from a incredibly small point. As it expanded the content was hyper dense by common standards. Might some of that extremely dense material condensed into heavy black holes?

Enjoyed your video so I gave it a Thumbs Up

Why not use graphics for all of the video and just do voice overlays

Brian Austin October 30, 2020 - 1:38 PM

I don’t think any black hole can be bigger then the space between joe Biden’s ears,that is a truly empty void.

The intermediate are in the super massive black hole. The intermediates descend into the super massive because as a black hole becomes larger it is not gaining velocity but is becoming heavier. This would migrate growing black holes into the super massive ones eliminating all intermediate ones.

U have absolutely no way to know! Just go ahead and keep lieing to us! As they do everyday! You have absolutely no proof what so ever. Just somebody’s say so! And that doesn’t make it true.

Madhurima October 30, 2020 - 8:51 PM

Karan Jani and his team at Vanderbilt University found an intermediate black hole I.e. 142 times the mass of the Sun just a few weeks back. Why are your videos not so up to date anymore?

brainretardant October 31, 2020 - 1:14 AM

Black hole get so big the warp space time to the point that "matter" cant propagate across the 3d cusp. It pinches itself off into ?

This was a cool video 😊

Steven Brodie October 31, 2020 - 7:12 AM

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.

David Mauney October 31, 2020 - 8:31 AM

You really have to be really be interested in this stuff to dig it. You can never get to the bottom or a black hole because you can never fall into one because you fall at light speed, and you can't go faster than light. Going faster means going backwards in time. You are stuck. From your perspective, 4 billion years is not even a second. For an outside watcher you would be there until your grandkids die.

Claudio Andrei October 31, 2020 - 10:45 AM

This feels like some sh*t out of movies but we actually live here .-.

Justice Vanpool October 31, 2020 - 12:53 PM

In my humble opinion an important question left out by this video is what it actually means for a black hole to be incapable of becoming more massive. Assuming that it's still possesses all of its other physical attributes such as gravity and the ability to suck in anything that gets nearby like a cosmic vacuum cleaner, how does it not become a more massive when it is still swallowing everything like there's no tomorrow.?

Beth Official October 31, 2020 - 6:09 PM

Black holes want to rule the universe, that is why they are getting big

Ram Kishan October 31, 2020 - 7:46 PM

Space is not static for assumed things like blackholes to do whatever the dreams of astrologists are

Christine LaBeach November 1, 2020 - 1:36 AM

Could it be possible for a black hole to lurk in the center of a super massive star? Seems kind of plausible to me. If the center collapses to a black hole the outer part of the star could be held up by the outward pressure from material falling in to the central black hole.

When black hole come

Turbo Tastic November 2, 2020 - 7:22 AM

Black holes are a math fantasy and don't exist. The latest photograph of a black hole in space was actually only 4 pixels of data. See Steven Crothers presentations on the math fantasies that Einstein created. Also check out the conspiracy of light website that thoroughly goes over the mistakes made in modern physics.

aliolci November 2, 2020 - 8:33 AM

write this down, our universe is in a black hole, thats why dark matter has gravity that s why it keeps expending

Marc Pabel November 3, 2020 - 4:35 AM

There couled verry well be something else then a black hole 🕳 that is having thee same symptoms. Also the meaning of size in black holes is not neccecerilly what we expect. What if smaller means thee opposite of what we think about it in black hole 🕳 variety?

I came across this reference of Dr mercy herbal product on YouTube . So I communicated with the Dr mercy for his hsv1 and hsv2 Herbal product. I received the Herbal product and it really worked out fine and so Great.. ""'''He is Highly Recommended on Hsv1 and 2, gernital herpes , anal herpes, oral herpes…I have Used the Herpes product from Dr which worked perfectly for me. i was referred to Dr mercy by a co staff who used his product too. so i can boldly say that if you are out there and you reading and needs help, you can reach him on Email, or whatsap number +2348141659546 for assistance to get in contact💕.💕.

The intermediate black holes might be so weird, that we cant see them. Or they are in such a spot, that we just cant see them.

Ahmed Salar November 28, 2020 - 8:01 PM

All the intermediate sized blackholes are around Uranus.

Kelig Avignon December 5, 2020 - 6:16 AM

what if the universe isn't expanding but there is a black hole wall that succ everything and it actually keeps approaching as it shrinks
hahaha just kidding…

Sultan J January 30, 2021 - 6:12 PM

I may consider the other theory's
but I will say it's just pop up like that in the early universe stages
when gigantic pockets of matter
just Cool down they start forming
and there is a science factor's will justify what i said , the age of the universe is not enough to build
this kind of monster's ..
so yes I think this how they
originated !
