[@warrentreadwelljr.treadwel2694]

Maybe central black holes who are of massive black holes are secretly dining off micro universes and the other dimensions that we speculate about. Due to their characteristics, maybe gravitational, the black hole can interact and feeding off them could cause massive growth. Figure that due to different laws of other dimensions, the size of an object there could be dramatically different in our universe. Feeding off another dimension itself and not just the objects inside it could be the answer to massive growth. Ever since hearing about dark matter and dark energy, I’ve wondered if these other dimensions could be the source of what we can’t see. The black hole is what allows “stuff” from alternate dimensions to enter our universe partially, we get gravity and energy from there but since it’s still located just off of us, we will not see it until the black holes pulls enough of it’s existence into the plane of our existence.

[@mickhughes6327]

As a kid, I thought the Big Bang could of been caused by Black Holes combining over time (a very long time), and after reaching a certain point, the whole lot exploded into our current universe. That would also suggest that there are objects out there far older than our current age for the universe.

[@dhenier4652]

Thank you for providing me with so much information on so many topics. You influence so many people's lives in such a positive way. I appreciate what you do.

[@W1se0ldg33zer]

Thank You Anton! You're such a great source of information!

[@katalytically]

We now have an estimate of the age of the current central supermassive black hole, but not of the previous supermassive black hole that existed before the merger. The mass ratio between the two black holes is 4:1, so the original Sag A* would have been around 3.2 million solar masses and the collider black hole about 800,000 solar masses. Then the question becomes how did the original Sag A* and the collider black hole form? They still have a long way to go before they have a somewhat satisfying answer. The collision theory cannot explain how the central black holes of the trillions of galaxies in the universe formed, because if the universe as we know it sprang into existence with the sudden expansion of space time 14 billion years ago, the supermassive black hole collisions 9 billion years apart cannot explain all the supermassive black holes that currently exist. If the rate of collision is once every 9 billion years, the universe has only experienced one round of SMB collision-mergers, far too few to explain the existence of all of the SMB's, nor does it explain how SMB's form in the first place, only how they can grow, and that there is a mechanism that overcomes the last parsec problem. My guess is that if there is essentially a head on collision, i.e. the black holes don't orbit each other, then it is possible for them to quickly merged, which could mean that the colliding SMB velocity is very high. Good news is that one mechanism has been found that explains how SMB's can merge, without the final parsec problem, but it still does not explain how SMB's originally form, since SMB's started forming only a few hundred million years after the Big Bang.

[@user-mg2ky1fv7x]

your book smart... I like that 😉

[@DavidFMayerPhD]

Galactic Black Holes do NOT form from accretion of smaller black holes or stars. They form as an inevitable part of the condensation of a galaxy. There is a popular misconception that black hole form only from stellar collapse. The key fact is that the radius of a black hole is NOT proportional to the cube root of its mass (normal for ordinary objects) but is DIRECTLY proportional to the mass. Hence, even a modest increase in density will convert an entire galactic core into a black hole. Densities can be very low, much lower than the density of the Sun, densities so low that they are mere cool clouds of gas with diameters of several light years.

[@charlottereed7603]

Thank you for providing the last bit of dopamine in my day that I needed to fold my laundry 😅

[@duhmez]

I hypothesize that the early supermassive black holes are created by huge clumps of dark matter pouring into them right from the beginning. If they dont colide with anything they would have no presure stopping them from funneling in. In addition, the final parsec problem maybe can be solved by gravitaitonal friction if there is so much matter dense as they dance around each other.

[@thetobi583]

hmm... that last black hole merger at 145-180*... If I remember right, there's also a few remnant arms/clouds that orbit our galaxy at about the same inclination. Coincidence? Perhaps something we should look into?

[@mudhutproductions]

Why yes, I do indeed feel wonderful after you say it. Shine on Science dude!

[@markmcd2780]

Another interesting video from Anton! I haven't yet found any answer as to how BH's grow or merge. See, GR suggests that, from the outside, as mass approaches a BH, it speeds up until (IIRC) at the event horizon (EH) it is at SoL. While a person falling into a BH would think things are normal, from the outside they'd be approaching ever more slowly until, at SoL they'd appear stopped. I kinda think at that point they'd also not be viewable to anyone outside. But, if that's the case, any mass attempting to cross the EH would, from our PoV, never actually enter the BH, being frozen in time from our reference. So how does any mass, even another BH, actually enter a BH? Also, why don't we see ALL light leaving the vicinity of the EH as extremely redshifted energy? I kinda think maybe it has to do with different conditions pertaining because the approaching mass is accelerating but I am unsure how that would change the issue nor how it could be the case where light is not extremely redshifted as it leaves the gravity well of a BH.

I have not yet read this paper, but your summary reports that the two black holes that became Sag A* formed 9 Bya. I trust your reading. You've become a highly skilled science communicator in recent years, but you lost me at the end. We can infer another such event in 10 years, where? Certainly not here in the Milky Way. Also, I wonder what we'll learn from the next GRB BoAT.

I got hooked on astronomy as a teenager long ago in the 1960's when I found a book written by Carl Sagan and a Soviet astronomer named Schlovsky (?) titled Intelligent Life in the Universe. The book is slightly dated because we have learned so much more about ourselves since the Hubble Space Telescope repair mission in, when was that? The early 1990's, I believe. Were you around to remember when the "Space Telescope" first went up and was an awful failure? What a scandal that created. But, NASA again came to the rescue. Such brilliance in that organization.

I'm no genius buuuut. For anyone who use to play old online games like Asherons Call and Everquest, when a landblock gets too many players or too many torches the landblock crashes (we use to crash landblocks on purpose). If we are in a simulation like many physics scientists have said, then blackholes very well could be crashed landblocks in our universe.

[@RaymondSwanson-u9y]

It occurs to me that galaxies can only grow at a set rate just like black holes. Only so much matter can enter a given region of space at a given rate. Anything faster is ejected. That mean galaxies can only grow at a given rate. Mergers can only add so much matter to the host galaxy. Excess matter is ejected. That would include massive black holes. Most would be ejected, as well as the majority of the invading galaxy. Only a fraction would even come close to the center, let alone slow down enough to merge. How many mergers would it take to grow Sagittarius A*. It would take millions. I don't think there's been enough time.

[@luudest]

Will the black hole have one day the same orientation as the rest of the Milkyway?

[@bluerendar2194]

For 'the same orientation'; sort of. If infalling matter on average has the same orientation, it will slowly move towards that orientation - but asymptotically. Therefore, it will never *reach* the same orientation, but once it consumes ~the current mass, it will be halfway, etc. For 'one day', assuming no other effects, that will be a very long time away. Current infall rate is miniscule, but not zero. Whether that 'one day' will actually be reached, depends on what happens in this far future to the universe itself - in big crunch or big rip scenarios, it won't.

[@tatersquad2000]

If you had the ability to place a signpost anywhere in the galaxy for others to find, where would you put it to maximize the chance others would look in that location? Only one answer makes sense: the center.
