"Wikipedia about Alcubierre drive says that faster than light travel is possible by manipulating space, though physically not possible..." hmm, is possible though physically not possible? If you'd like to premise a question on a statement in Wikipedia, quote the exact statement, sentence or paragraph. Use the `>` symbol to display as a block quote. I was going to show an example but I found that the word manipulate or manipulating do not even appear in that article. *Don't paraphrase, quote exactly!*

@uhoh possible Mathematically impossible in reality. Is the only way it can have sense. Like a square root  of me^2 can be me or my negative :))

Does this answer your question? [Is the influence of gravity instantaneous?](https://astronomy.stackexchange.com/questions/5869/is-the-influence-of-gravity-instantaneous)
