Not really for that addon, it was just a small I put it together in 10 minutes addon.

And Vision, your addon still look good on my laptops despite the older graphics.

I remember seeing that image. I also remember getting confused for a while because I thought you downloaded another black hole addon with red accretion disks, wherein reality, it is just that your computer rendered them differently due to the graphics of the actual black hole addon being too high for older computers or computers with weaker graphics cards.

That one though, I do not remember seeing that. I just have to wonder why is the "atmosphere" bluish, and how large does it radius extend from the center?

I think Anthony added a planet around the black hole.

I checked the picture. He added Earth.

I added the entire Solar System around the closest star to Sagittarius A* to see how it would compare.

That's Nice! Could you somehow include that as an addon separate from Vision's addon and put it here? It's for testing and sightseeing purposes. Thanks

Thanks a lot, Anthony! I'll send some screenshots here so that you'll see what it would actually look like from Earth

Imagine waking up to this, thought I think in reality, you'll not be able to see it, because though not a quasar, the energy of the jets should be high enough that its brightness will be several times that of the Sun

Wow!

Beautiful and majestic :smile: .

Anthony_B_Russo10, thank you for this addition to my addon! :clap:

Really... It's unfortunately unrealistic.
I think Sagittarius would have shot at our Earth or any other inhabited planet in no time.

The accretion disc at black holes rotates at crazy speed.
The light emitted by one edge of the disc will experience a red shift and the photons at the other edge will be blue.
At the blue shift, the electromagnetic wavelength becomes shorter and the frequency increases, i.e. there is a shift to the ultraviolet part of the spectrum.
In other words, there is much more radiation (and gamma), and this is probably catastrophic for hypothetical life.

And the closeness of the accretion disk to life as we know it isn't a plus...
Keep in mind that the drive's temperature is very high and most likely there would only be solid scorched worlds in reality.

It would also kill all life and a relativistic jet with its radiation.

So living next to such monsters... not a good idea.

And there probably wouldn't be any planets there. The black hole would have pulled everything over.

Vision, thanks for the reply, and yes, Anthony added this addon not for realistic reasons but just to test how a black hole would look like in our skies. That being said, there is a hypothetical possibility that there is an area beyond the Black Hole's accretion disk and radiation but still within its gravitational influence that is balanced enough for planets to exist. That they called a black hole's "Habitable Zone" of sorts. More cam be explained in this video:https://www.youtube.com/watch?v=PjbtCy5XEjM&t=613s , though obviously, I think the research papers would be better suited for you: https://iopscience.iop.org/article/10.3847/1538-4357/ab1b2f, and maybe some other research papers related to that may appear in your search as well. The film Interstellar may have made a few glimpses of that possibility, but then again, all that is just based on some possible hypothesis and a little research. I also remembered that hypothesis as being the basis of Anthony's Black Hole system addon.

Either way, I really enjoyed your addons, especially when I took pictures of them via Celestia's capture image function. That being said, I'm gonna await your next addon release, and then install it and explore it with the same enthusiasm I did with all your other addons, because simply put, they are so good. Thanks a lot, and more power to you

Pretty much. If any, I'd think that the Accretion Disk of the largest and fastest-spinning black holes are the largest, strongest and fastest cyclones ever produced in the Universe, if we consider them as such

This is an addon requested to SVision by Gurren Lagann for the Collaborative Worldbuilding Project (CWP), and he made it really well. Just posting it here so that anyone who follows this topic and wants to complete their black hole addons may do so, and also because SVision gave me his blessing to upload and share the addon here. However, since this is for a fictional addon project, this is not a realistic black hole unlike SVision's other black hole addons.

The Name of this black hole is The Oculus, and it is a supermassive black hole with a radius of 626,000,000 kilometers, which gives it a mass of 2.11916E8 or around 200 million solar masses. Around 50 times more massive then Sagittarius A*, the supermassive black hole at the center of our Milky Way Galaxy.

The Oculus.jpg

Due to its far out distance of 459.99 Mpc, it requires Janus' Commit that allows objects within a 1-billion LY radius to be rendered, or the latest version of 1.7.0, that has that feature as well.

The accretion disk, though, is very hot.

Yep. Black Holes are a thing of extremes. They are very gravitationally powerful, they are very massive and dense, their event horizons are very cold, nest absolute zeroes, and yet the matter that they absorb and form into the accretion disk are very hot, to millions, if not billions or trillions of Kelvin, thus making them emit the most radioactive rays ever. And while they themselves are the darkest objects in the universe (Excluding Dark Matter), they are the sources of the brightest objects in the universe, which are active galactic nuclei, especially quasars. Truly Black Holes are a marvel of the Universe
