Black Hole Video

Today, I was going through NASA's website in search for more black hole information :orly:, and I found this ↓ amazing video that perfectly shows how large enormous black holes could be. 

 

Hint: tun on the subtitles for more info on those black holes that you'll see. 

Spoiler

TON 618 is circled on the image below:

Remember, black holes are indeed very dangerous, mostly because of spaghettification and radiation, but the best way to stay save is to not leave the Solar System :darling: 

Thank you for reading and stay safe during your interspace travels!

You forgot the Luna counter :orly: .

Theyre only dangerous if you fear death :BrightMacContent:! I’m curious to know how spaghettification would actually work… like is your body then torn to shreds, or do you end up like a cartoon character :P ?

To quote this article, "When an object gets 'too close,' it will start to experience tidal forces. Here on Earth, the ocean has high and low tides which are caused by the Moon's gravitational pull tugging on Earth and its water. So, tidal forces refer to the distortion of one object by another due to the difference in the gravitational pull on the near and far side of an object. Due to a black hole’s extreme density, objects in its vicinity will experience extreme gravity and hence extreme tidal forces that can even pull the object apart :sealed:. The effects of a black hole continue to escalate as an object approaches a black hole's event horizon: This is the point of no return, or the boundary surrounding a black hole beyond which nothing, not even light, can escape. For any object falling into a black hole, the part closer to the black hole will feel a stronger gravitational pull than the part farther away from the black hole. This difference in gravitational pull increases as the object gets closer to the event horizon. The difference in gravitational pull isn’t unique to black holes, but their extreme density creates an extreme effect."

Steven Hawking first described spaghettification in his book "A Brief History of Time," which I am currently reading :orly:

Apparently, black holes can also flatten objects like pancakes. This is a phenomenon known as “pancake detonation” that primarily happens with supermassive black holes. In this phenomenon, stars that get too close to these black holes will be flattened and compressed by tidal forces. This short-lived “pancake” distortion is followed by an explosive release of thermonuclear energy :scoots:.

I fixed it, don't worry

That answers that question :wacko: .

Must be a long book and boy you must have quite an attention span to read a whole book on astrophysics, presumably that's what it's about :wacko: .

Heheh, up until the last hour, I kept imagining how you would flatten a pancake even more, additionally nuclear pancakes exploding :laugh:. "But it's already flat!" 

Yay :yay:. Can't not have it :orly:.

I love space stuff! :Twilight-clap:

 

This makes me remember those videos showing the greatest stars known by humankind. I've always loved those videos.

Watching the scale is always impressive, but we can't even imagine how HUGE those sizes are. :o

 

Have you ever been on a highway and wondered how many trucks full of asphalt it requires to build the roads just to reach the next village?

Have you ever wondered how much asphalt does it require to connect two countries with lots of roads?

The mental strain you must suffer just to realize that, is simlply incommensurable... Well, that is just less mass than a grain of sand in the sahara desert compared to the smallest black hole.

I just can't even realize how massive they are.

 

A curiosity I discovered recently...

I always wondered why black holes looked liked this, but I recently understood why!:DD

The acretion disk is, as the name says, a disk; but gravity is so strong that curves the light path. That makes us be able to see the upper and bottom part of the acretion disk at the same time. I've made a pretty professional diagram!:proud: (I'm not an astronomer so I can probably be wrong)

Hmm...

Reading about spaghettification and pancake detonation made me hungry.

As much as I know, this is the correct explanation, @Midnight Insight! I also heard of even bigger black holes, like Phoenix A, but it is closer to us than TON 618, so TON 618 might have grown since then (or something else happened to it. We can't just see it yet :sealed:).
