Question: what are the dots after a sentence called?
Answer: The ellipsis, …, (plural ellipses; from the Ancient Greek: ἔλλειψις, élleipsis, 'omission' or 'falling short'), also known informally as dot-dot-dot, is a series of (usually three) dots that indicates an intentional omission of a word, sentence, or whole section from a text without altering its original meaning.
