How does a black hole disappear?

Answer

Dear Florian,

first the following: you are talking about astrology in your question.

AstroLOGY is a superstition without any scientific basis. Some people believe in it, most (fortunately) don’t. AstroLOGY is not a science. You can’t study it anywhere at a university. Horoscopes are just deceit of gullible people.

But you probably mean actually astronomy

AstoNOMY is astronomy. This is a science like physics, chemistry, mathematics, biology, geography. You can study it at university, and research in astronomy is done according to scientific methods (measurements, experiments, mathematical proofs and deductions).

It is very good that you are interested in the universe. Astronomy is a very fascinating science that is very well suited to do as a hobby. But please don’t bother with horoscopes! Who still believes in that? There is still no evidence that astrology works. I’d be sorry if your interest in astronomy goes in the wrong direction.

Now about black holes….
Dear Florian, that she does not hear things that are easy to understand. A black hole can form when a very massive star comes to the end of its life. Then a black hole can form, it may exist forever. But I would like to learn a bit more about planets and stars before starting something as difficult as black holes.

Did you know that in Flanders there is an association of people who have astronomy (astronomy) as a hobby? Well, that association also has a youth section, the JVS, the Youth Association for Astronomy. They may even have a branch near you!
