perspective

I pondered my orb last night

She’s represented by black pixels.

the light hasn't reached is yet

The light will never reach us, space is expanding faster than light between here and there

See my response below to Captain Aggravated about how dilute those large stars are.

It's an interesting question whether anybody would actually feel spaghettification 😁 I actually don't know. You can use physics to calculate the proper time derivative of the tidal forces, but you need biology to define the start (and end...) of the process. My intuition says that it probably happens too fast, so once the tidal forces are strong enough to be perceptible, they grow strong enough to rip you apart before you realize (again, just a hunch).

Right? How can you not know it?

Hmm, am I in the star yet? I mean my body is now made of million degree hot plasma, but I'm still not sure....

Black homes are so massive and heavy that they bend light (well, technically every piece of mass does, even yo momma). It's bend so extreme that that accretion disk appears warped.

A similar thing happens with neutron stars that can also bend light in such a way that you can actually see part of the back of the star (if you were able to see it anyway, it would be dark) as light that would be emitted from parts of the back would warp around to the front where you could see it

Yep, you got it right. The accretion disk is actually really flat. Those images are produced in simulations that take into account the curved (and very complex) paths light takes in the vicinity of a black hole. These images really depend on the angle between the line of sight and the disk.

The second one. The image is simulated as how an external observer would see it. It was firstly done for the Interstellar movie.

Or is it exactly like saturns rings but we see the whole ring bent round the top because a black hole bends the light around so we can see it?

Hit the nail pretty hard on the head there

Yes, but red supergiants differ from the sun in that their photospheres are extremely dilute and don't have a sharp transition to the corona. I don't know the details of this particular star but take Betelgeuse as an example (it's probably not particularly large for this catrgory), it's radius is ~640 the sun's per Wikipedia, which gives a volume of ~260 million that of the sun. But it is only x15 times as massive as the sun, so on average ~20 million times less dense.

In the case you are unlucky enough to encounter the black hole "heads on" and fall into it radially, the proper time timescale to spaghettification is the size of the event horizon divided by the speed of light. The most supermassive black holes will have a horizon of around one light day, so that's what we're working with, a matter of days. If you come in on the most tangential orbit possible though, I guess you're buying some time but I've never heard that it's supposed to take many years of proper time (I doubt that claim a little bit, but haven't calculated myself).

They are quite similar to electromagnetic waves, but also quite different. They are produced by masses accelerating (just like EM waves are produced by charges accelerating), and indeed cause orbital decay. But this orbital decay is only important in relativistic systems (so the Earth, which is orbiting the sun at 0.0001 the speed of light, is not going to fall into the sun because of gravitational waves).

Gravitational waves do cause orbital decay as the energy required to create them comes from the objects own momentumn.

I highly suggest you look up PBS spacetime on YouTube. They have an incredible amount of very informative videos on black holes and gravitational waves. As well as pretty much any other astrophysics topic you can think of (and many you can't!)

I oweeeeeee my Sol to the black hole...

Yes.. approximately 18.2 billion light-years out (⁠☞⁠ ͡⁠°⁠ ͜⁠ʖ⁠ ͡⁠°⁠)⁠☞

the scale is absurd for my monkey brain, its impossible for me to "get" it at all.

Man, I think about that all the time. We aren't even a drop in the bucket, not a blip in the history of the universe. To me that makes life immeasurably precious. We get to experience and explore a small moment of infinite vastness

We are stardust, we are golden

We are billion year old carbon

And we got to get ourselves back to the garden

Spatially small =/= doesn't matter. You can't just jump from physical characteristics to values like that. What happened to being scientific?

Or the Bobs

It would take multiple galaxies of matter to pull the material together, but if you're planning on building a megastructure of this scale that's probably not any trouble for you

The problem is the layout.

It needs horizontal dividing lines to show that the bodies are presented in pairs at the same scale.

When you first look at it, it seems like all six are in one picture at the same scale, then you start noticing things appearing twice, and think "hang on that's not right" and work it out, but just two lines would have solved it immediately.

Design, people! Design!

Bigger thing even bigger than very big thing

yep. space facts can be quite arousing, indeed.

better than having a stroke to nude pics.

O <---- OP's mom Tom ----> .

You have a way with words.

there isn't one! So feel free to make it up, you probably won't find it, or won't know when you've found it, but the mere act of looking will point you in the right direction - going out and enjoying the absurdly rare phenomenon of being alive. You and I are a cosmic anomaly, friend, isn't that cool?

for a more comprehensive guide on what do when you realise life is meaningless: refer to existentialism and absurdism

yeah, that's kind of the problem i'm having lol, doesnt help that his video titles are often a little obtuse.

that's possible, but vasuce has a very specific video style, i guess i should probably go watch a couple veritasium videos to be sure lol.

The obvious answer is that it's actually something related to "the scale of the universe" which is another really cool project, but i don't think it's that one either.
