do not put a dyson sphere and swarm around a black hole

[GSG rockstarkai]

i was playing around in sandbox and i put a dyson sphere and swarm around a black hole a first it was fine but in kept getting brighter and brighter too the point purple green yellow and black dot appeared on my screen at the center of the monstrosity i had made so fair warning i guess.

Well, that depends. A black hole only sucks stuff in when its too close. Right outside of that event horizon insane gravitational lensing occurs. Like a magnifying glass.
In real life we exploit this effect by using stars as gravitational lenses to get some magnification out of it.
Either this is a bug or that was the intention of the devs.

Point being, they don't emit radiation, other than Hawking radiation and emissions from any accretion disk they might have. A big black hole doesn't emit a lot of hawking radiation, and a black hole big enough to have an accretion disk isn't really a good place to try and build a dyson sphere, seeing as the whole point of one is capturing the radiation of the star in question

CORRECTION: Stop saying dysonspheres around black holes is stupid or a bug... Because...

Dysonspheres around blackholes are a real frelling theoretical concept. But they are actually just reflective spheres you construct around them.

You see... Singularities in real life are actually correctly called "Ringularities". Yes. Because black holes has ONE thing in common with basically every other object in the universe, they SPIN. And their spin is so powerfull, not only does it cause the single point of infinite density to become an infinitely dense ring, but it also drags Space.

When a black hole drags space, anything falling into it parallel to the direction of the spin will actually gain momentun/energy if it manages to escape again. You can do this by simply throwing mass into the black hole as your rocket flies towards it.

Even better, due to this spinning spacetime, you can simply shoot photons towards the edge of the event horizon, which will cause "Superradiant Scattering".

To do this you simply just need to encase the black hole in something that is similar to a dysonsphere, a sphere of super effecient mirrors to reflect the energy around inside the black hole. This will cause the light to bounce around inside and constantly intensify as it steals spinenergy from the black hole. In fact, this can create some of the most powerfull technological bombs you can imagine in the universe, as if you do not let this energy out, the sphere can blow and release all the energybuildup inside with a force akin to a supernova.

Not only that, if you somehow are able to build one around the accretiondisc of a black hole, somehow, you can gain more energy than a star ever could depending on the intensity and mass of the accretiondisc. As said before. Black holes can be some of the brightest, hottest places in the universe as they make energy the most effecient ways possible, in multiple ways... Just need the right conditions. Otherwise they are dark spots that just emit hawkin radiation.

It is also a much smarter move than a dysonsphere once you are able to travel to a black hole, as such a "dysonsphere" only needs to be the fraction of the size a normal one would around a black hole the mass of our sun. A couple of large asteroids would be enough to build it.

And is the longest theoretical way to keep a civilization powered towards the theoretical heatdeath of our universe. Black holes spin. Hawkin radiation is NOT the ONLY form of energy they can provide or give back to the universe.

no, it's a penrose sphere, stop oversimplifying it, the actual maths is very interesting.

You know I didn’t expect it to come to this and I have learned a bit more about black holes than I would have liked. All this originally was. Was don’t do this it did this since I thought they hadn’t finished working on putting Dyson sphere around a back hole
But hey I don’t know.

What!! Is that the output side of blackhole. One side in one side out

Nah, just the superheated gas of the accretion disk getting accelerated by the immerse gravity outside of the event horizon.

[Kyrros]

Yes, both the radiant and rotational energy of a black hole's accretion disc can be harvested since things in the disc have not actually fallen beyond the event horizon (and therefore lost to this universe)

It's been linked here on the DSP forums before, but it never hurts to enlighten even more folks.

... besides, who doesn't love a good Kurzgesagt video?!

I like how the forums go sometimes.

OP: I'm building a ring around a black hole and I'm getting weird visual effects that are super bright?

Forum: Once I played a game and my computer melted.

OP: Ok? My screenshot though, how do I fix this? Do the developers know?

Forum: This is how you built a heat-death of the universe resistant habitat for the end of civilization!

yes his black hole bomb going to melt his monitor, he forget to dump extra energy
