Topic: Are astroids too small to be swallowed by a black hole?

This is an image of our sun getting sucked into a black hole (Sagittarius A), but I noticed that the simulation has a bunch of asteroids in the solar system going into orbit around the black hole. Do they not get swallowed up because they are too small?Anonymous B joined in and replied with this 7 years ago, 40 minutes later[^] [v] #949,264
Autism particles are too small to be absorbed by black holes.

A lot of the objects surrounding the black hole will orbit as normal. You could replace the sun with a black hole of similar mass and the earth would still orbit it just fine.

I actually knew that last one from a video I watched where the guy did exactly that. What I did was launch a black hole at the solar system to see what gets swallowed up. All of the inner planets and the sun got swallowed, but the outer planets managed to survive and found new orbits around the object. This also includes several asteroids and comets.

They don't really expand though do they? They shrink over time due to Hawking radiation and eventually dissipate.

Old black holes never die, they just fade away. So says veteran cosmologist George Ellis of the University of Cape Town in South Africa, who suggests that the cosmos may be littered with an untold number of shrunken black hole remnants.

I keep looking for updates on Dark Matter because of course it really matters and there is a little new info

This is a common theory

Much remains unknown about dark matter, the mysterious substance that makes up most of matter in the universe. Findings of a new research, however, could help scientists determine the distribution and eventually the true nature of dark matter.
The Invisible Dark Matter
Dark matter makes up about 85 percent of all matter in the universe, but it has remained invisible because it does not appear to interact with regular matter such as light. Astronomers cannot detect dark matter using current instruments. They only know it exists because of the visible effect of its gravity,
A new study by two astrophysicists from Australia and Spain, however, may bring science closer to figuring out where the mysterious substance may lie.
Intracluster Light In Galaxy Clusters
Mireia Montes, from the University of New South Wales in Australia, and Ignacio Trujillo, from Instituto de Astrofísica de Canarias in Spain, said that faint light in galaxy clusters known as intracluster light can map the distribution of dark matter and help astronomers understand this invisible source of gravity.
The researchers explained that intracluster light are a byproduct of galactic interactions. When galaxies interact, individual stars are ejected from their home galaxy and float within the galaxy cluster. These stars then end up where most of the mass of the cluster, mostly dark matter, resides.
Locating Dark Matter In Galaxy Clusters
The isolated stars and dark matter that form the intracluster light both follow the gravitational potential of the cluster itself. Because the two follow exactly the same gravity, the intracluster light can indicate the location of dark matter.
"We have found a new way to see the location where the dark matter should be, because you are tracing exactly the same gravitational potential. We can illuminate, with a very faint glow, the position of dark matter," Montes said.
The researchers said that the findings mean researchers can map where dark matter resides just by using deep imaging observations of galaxy clusters.
The findings were published in the journal Monthly Notices of the Royal Astronomical Society.
