What is a black hole chat?

By Black Hole Chat is a disappearing chat or a single message that can be permanently and irrevocably destroyed. To make it work, you send a message with a timer. Once the message is opened, the timer begins. After the timer finishes, the message is destroyed and disappears forever. Since it has not passed through any other communications system, like a 3rd party instant messaging platform, every record of its existence can be eliminated.
