'Black Holes At The Center of Galaxies' W/Brian Greene #blackhole #space #cosmology

Is there's a supermassive black hole in the centre of our galaxy? And why it's common for a to have Black Holes in center of Galaxy.
Jion Brian Greene as he explains how these massive Black Hole may have been formed and how early stars have become "GARGANTUAN" Black Holes. As studied by Sloan Digital Sky Survey on a vast number of galaxy it is concluded that most of them have Massive Black Holes in their center. In addition he also mentioned that how Black holes at the center of galaxies can have a mass of millions or billions of times the mass of our Sun as they have been here for billion of years sucking from environments. #briangreene #blackhole #blackholeexploration #SagittariusA

Still mad about how in 6th grade I told my entire class and teacher that there was a black hole in almost every galaxy and he told me I was wrong.

Anything with strong gravity tend to be the center of everything

[TheCgOrion]

I wouldn't think it's not possible to have a formed galaxy without a black hole at the center, and anything large enough to create a formed galaxy would automatically become a black hole, before the formation even "completed".

We are infants discovering we are alive in a universe we know very little about.

Sun 🌞 makes reality black holes rip reality apart fascinating

[Supermaaaaaaannnn]

I love how his starts to answer rather than be reaaaal honest and say we simply don’t know. At the end of the day.

[MrFallenne]

The likelihood that blackholes are responsible for the formation of every galaxy in existence is extremely high.

[johvidzvidz]

We have no idea what's going on beyond our solar system really! It's all just pictures of tiny dots

[nuclearsimian]

Surprised he didn't mention the proposed hypothesis that supermassive black holes arose during the initial expansion of the universe, that those black holes were a result of an incomprehensible mass of hydrogen and dust that was crammed into itself and ended up forming these monsters, but it may be due to the proposal not standing up to scrutiny or not having enough research behind it yet.

Same reason stars at the center solar systems, their gravitational pull is pulling on everything in them. That’s why galaxies rotate is because they are orbiting a black hole.

[stanhartman]

There are places were gravity warped time and space, we're on the other side of one.😊

[tonywhitby]

Could these black holes be the entrance to a new universe, like a big bang, and the material being sucked in will be used to create the new universe?

[cpi_productionscreatoxx]

Because the most massive object in a region will always center everything around it? The interesting question would be, where stars first, or black holes?

[NoEggu]

Theoretical physicists and cosmologists routinely say that black holes were formed. I believe that they are probably wrong.

At the time of the big bang, the entire observable universe was a single black hole (or so it is believed).

At some point, the pressure from that unimaginable amount of mass produced an unimaginable amount of heat -- enough to overcome the unimaginable amount of gravity of the black hole, resulting in the big bang.

When the big bang occurred, not every piece of mass was released as we see stars and planets and asteroids, etc. That initial, single black hole, when it blew apart, broke into not only stars, planets and the rest, but it also broke into countless smaller black holes.

And when I say "smaller" black holes, they are not small (they are massive). But compared to the size of the once single black hole that everything in our observable universe was in, today's black holes are much smaller than that initial, single black hole.

So our black holes that we detect, today, were never formed. They are simply smaller segments of initial black hole that exploded into what we now call our universe.

"It's uncertain" is the only thing that guy said, that anyone can be certain about

[stevedone]

We only know a small fraction of a percent of why shit happens in the universe. It is like looking at a teaspoon of ocean water and figuring out all the species of life the ocean contains.

[Blitznstitch]

I don’t think it is a literal hole. I think it’s a mass that grows in size, it’s matter

[jamesdelcol]

There is theory, but galaxy formation is not perfect. They don't know everything. The Universe is so amazing with these new telescopes. Hubble blew my mind and now JW telescope is wild.

[christianmcallister]

I’m guessing as well that with each galaxy time moves at least slightly different depending on the gravitational pull of the quantum fabric from the black hole on the specific solar system? Maybe different placement in a galaxy and black hole size variation it ends up dilating time? Huge assumptions on my end as I am not a physicist and I do not claim to be but hopefully one day I will be 👍 quantum physics makes me so curious. We grow up defining what we think we know only to refine every definition we already came up with making it that much harder to understand. I hope there’s a day we understand most of the universe but that will most likely never happen.

[shara]

Why are they so hesitant to say for sure, that black holes are the reason for galaxies, when they are in the center of galaxies.
Im mean, is it going to disprove a pipular theory that goes against the establishment, so they wont even say, hey, its possible they cause galaxies .... Or something to that affect- i think thats what joes hinting at
