When a child dies, are they in a universe where their death didn't occur?

**Edit: A person’s life is not different from a universe’s life. You have free will when you compose free will as your universe. A father is a universe that is his son’s free will.**<br><br><br><br> With the Many-Worlds theory, when a person dies, they die in a universe where they died. However, in a universe, the person lives. So the person lives in that universe, or the person lives in a universe where the person lives.<br><br><br><br> A father and a son are like two different universes. A father lives in his son as his son, and his son lives in his son as his son. In his son’s universe, his son dies. In his father’s universe, his son lives. In a father’s universe, a person’s life is a universe where his family lives forever.
