Black hole stars may have been the largest stars to ever exist. They burned brighter than galaxies and were Larger than any star today or that could ever exist in the future. But besides their scale, what makes them special and weird is that deep inside, they were occupied by a cosmic parasite, an endlessly hungry black hole. How is that even possible?

From that distance, our planet would never complete a full orbit from its formation to the destruction of the star.

[@Gamer-df6if]

​@@thelastroman7791 I've actually simulated a quasi-star in Universe Sandbox and it took Earth 620,270 years to orbit it in its habitable zone (semi-major axis = 9.97 ly). It definitely will complete a full orbit, but it only has a handful of orbits left. Wikipedia stated that a quasi-star lives for only 7 million years at most. That means Earth can only orbit it for ~11 times before it dies. Compare that with Earth around Sun before the latter's death counted onwards from now, which is pretty much still 5 billion orbits left.

Absolutely Incredible work. I re watched this work, cuz its simply superb.

[@thumbsup8985]

The part where the accretion disk rips apart the star literally gives me chills. It's like, a reverse supernova. Instead of gravity rebounding or collapsing entirely, it's completely overwhelmed by the energy of the core. The illustration of the event is the best kind of eye candy 👍

[@kaitlyn__L]

@@ZHL242 it also brought it to the public’s attention. Star Trek uses relatively accurate visualisations now, but in 2003 they used a literal black star with no lensing in the accretion disk. And they had advisors that a lot of other sci-fi didn’t, but just didn’t see the need to render all that. But now it’s mandatory, to the extent that sometimes there’s glitches and they don’t make the lensed portion always face the camera, because not having the effect at all would be unthinkable.

[@arkfish]

I'm not complaining though. Those choruses made me feel like i was going to heaven
