I have recently encountered a question about Black Holes, marked as a duplicate: Do black holes exist? The question asks whether black holes have information inside and if no, how a hollow sphere can be considered a black hole. The question is marked as duplicate of the question How long does it take for a black hole to form? which is totally different and concerned with the time it takes for a black hole formation.
In short, this question is about information inside, the linked question is about formation time, they cannot be duplicates.
I do not know why people voted to close it, possibly they only read the tite.
