Cookie Monster = super-massive black hole

The good news is that if something like this were coming our way, we wouldn't know it until it hit us.

 

[Ruddles72]

Yes! A much much smaller scale. We've seen Sagittarius A* (our own super massive blackhole) give off bursts of Xrays as it feeds but it's still technically in a "dormant" state right now as there isn't much else in the galactic center but other black holes.

All your posts in this thread have been educational, concisely written, and simple without (feeling like they are) talking down. Really appreciate your posting.

And they know this is the second most powerful in the history of the universe how?

*That we've witnessed so far

 

[baudelinog]

Pink and blue explosion?

Lol!

 

[Lucreto]

Shit like this makes me realize how special life is and how lucky we are to be in a place in the universe where we aren't on the precipice of imminent destruction by a ginormous ass explosion shooting black hole.

....As I go back to reading people argue about Fallout 4's graphics.

We could have to worry about this

looks like Rosalina had a comet accident.

hopefully she had her insurance up to date.

Ideon has exploded.

Okay, the black hole itself has a mass more than ten billion times that of our own sun. However, over the last 100 million years, it has devoured a galaxy or such that has a mass of 600 million times that of our Sun, which has triggered this ongoing explosion (eruption?) of energy. As stars get eaten by a black hole, they get crushed down and go supernova. Some of the mass of the star gets gobbled up by the black hole's event horizon, but other parts of the star's mass get blasted out faster than the black hole's escape velocity.

So, over the last 100 million years (from the perspective of our perception, it really happened a long time ago), this black hole has been eating stars at the rate of about 6 a year, if all of the stars had the same mass of our Sun. The resulting regular chain reaction of novas has created a massive plume of energetic matter that has displaced and pushed around the 10 billion sun-masses of matter mentioned in the article.

At least that's what I think is happening based on my somewhat simple understanding of astrophysics.

How do black holes have an escape velocity? I thought the reason they couldn't be seen is because not even light is fast enough to escape a black hole's gravity.

 

[FyreWulff]

It's neat because any matter on opposite sides of that cavity won't be aware of the other's existence gravitationally for 600,000 years

It's really amazing to actually see the "infinite" quantity of energy in the universe. And we're sitting here fighting over whatever little we have. In fact, if we had that much energy, it'd be free.

Scary stuff.

By measuring it.

 

[sphinx]

the thing that blows my mind is

"an explosion has been on going for 100 million years"

my mind shuts down at the thought.

As a general rule, nearly all space photos are re-colored. Most are taken in IR or other non-visible frequencies. (Correct me if i'm wrong.)

Should you see a nebula with your own eyes, you probably wouldn't see anything interesting or pretty.

Our eyes suck.

The escape velocity is higher than light speed inside the event horizon.

Outside the event horizon, the escape velocity is gradually lower, inverse-square law with respect to distance.

Same as how escape velocity from earth's surface is something like 11km/s, but escape velocity from 500km above the surface would be significantly less.

Lmfao, suddenly it all makes perfect sense!

 

[TheOfficeMut]

600,000 light years? Wtf. That's six times as large as the Milky Way.

This image may help:

The relativistic jets shoot out particles and light that have not yet entered the event horizon along the rotational axis of the black hole (the dimples you see in the ergosphere). This is a very small amount of the total matter consumed by the black hole.

 

[User 406]

So, what happens of Sagittarius A absorbs one of the other black holes?

We die.*


* In about 27,000 years or so.**

** Assuming it didn't already happen about 27,000 years ago.

Yeah, while we fight over caches of scrap solar energy stored in the form of fossil fuels and fumble trying to come up with ways to harness the relatively little sunlight that hits our planet in enough amounts to meet our usage, there are countless phenomena going on in the universe that generate enough energy in a single second to keep mankind going for millions of years.

Absolutely mind numbing and fascinating.

Why does stuff like this exist in nature? This is another mind boggling thing also that shouldn't exist in space. https://en.wikipedia.org/wiki/CMB_cold_spot
Its literally billions of light years of nothing. just empty blackness.

 

[nelsonroyale]

Scale so far beyond our capacity to understand. Incredible.

Thats a fairly strange way of putting it...If it is proven to exist through detection and observation and it doesn't fit the models then either the models need modifying. Our understanding of what is possible is provisional...
