So FTL anything isn't possible, no matter the method, full stop. Einstein's general relativity theory is pretty much demonstrated to be 100% correct, with no real evidence of it being wrong (at least on a macro scale). As per this theory, we know the relationship between space and time, time dilation, e.t.c Any FTL device can be used to create paradoxes, like sending a message back in time that prevents the message being sent in the future. These paradoxes are simply not possible, as it breaks causality. Therefore FTL is not really possible. All the FTL stuff like Alcubierre drive is just clever way of playing with math. Math is just a language that is used to express relationships in reality that we know, its not a one to one mapping of reality.

> FTL I wrote explicitly about a subluminal warp-drive at 1/100 percent of light speed. There is no hint in my text of alternative theories. On contrary I cite Bobrick and Gianni Martire: https://iopscience.iop.org/article/10.1088/1361-6382/abdf6e https://iopscience.iop.org/article/10.1088/1361-6382/abdf6e There was a continuous string of serious publications since Alcubierre's work. There is no need that this warpdrive accommodate living beings, it could be a nanoprobe. What's important is to start somewhere. At some time engineers must enter the arena and discuss how to make a real warpdrive.
