How does a topic fall into a black hole on the physicsforums? Someone posted a new question about finding a book, I gave a response and upon sending the message, physicsforums said the topic was in a black hole. What is this?

In summary, a black hole is an area in space with an extremely strong gravitational pull, formed when a massive star collapses. The size of a black hole depends on its mass, with the largest known black hole being 66 billion times the mass of our sun. Nothing can escape a black hole once it has passed the event horizon, including light, matter, and information. Black holes are detected through their effects on surrounding matter and light, and there are three main types: stellar, intermediate, and supermassive black holes. Supermassive black holes are the largest and are commonly found at the center of galaxies.

It's just trying to be a clever way to present a 404 not found server message, nothing more 
1. What is a black hole?
A black hole is an area in space with a gravitational pull so strong that even light cannot escape it. It is formed when a massive star dies and collapses under its own weight.
2. How big can a black hole get?
The size of a black hole depends on its mass. The more mass it has, the bigger it will be. The largest known black hole, known as TON 618, has a mass of about 66 billion times that of our sun.
3. Can anything escape a black hole?
No, nothing can escape a black hole once it has passed the event horizon, which is the point of no return. This includes light, matter, and even information.
4. How are black holes detected?
Black holes are detected through their effects on surrounding matter and light. Scientists also use specialized telescopes and instruments to observe and study the gravitational effects of black holes.
5. Are there different types of black holes?
Yes, there are three main types of black holes: stellar black holes, intermediate black holes, and supermassive black holes. They differ in size and mass, with supermassive black holes being the largest and most commonly found at the center of galaxies.
