There must be some official basis, just like with the classic mechanics. Enshe couldn't have known EVERYTHING. The current scientific knowledge of the world is not accurate and complete. Who knows what other secrets will surface in the depths of the STO.
Besides, I already said that the existence of exotic matter has already been experimentally proven, so it's not such heresy. But the possibility of a warp bubble really makes you think. But I think there is a way out.
And what can you say about the expansion of the universe? After a certain point, it begins to expand at superluminal speed.
And this, by the way, is within the framework of General Relativity. Proof.

Even professionals (physicists, astronomers) often answer the question: "Can we observe a galaxy that is receding from us faster than the speed of light both at the moment it emits light and at the moment its signal is received on Earth?" - "Of course not!" Intuition based on special relativity (SR) kicks in, which one cosmologist aptly called "the shadows of SR." However, this answer is incorrect. It turns out that it is possible. In any cosmological model, the recession velocity increases linearly with distance. This is due to one of the most important principles - the homogeneity of the Universe. Therefore, there is a distance at which the recession velocity reaches the speed of light, and at greater distances it becomes superluminal. That imaginary sphere, at which the recession velocity is equal to the speed of light, is called the Hubble sphere.

"How is this possible!" the reader will exclaim. "Is special relativity wrong?" It is true, but there is no contradiction here. Superluminal velocities are quite real when it comes not to the transfer of energy or information from one point in space to another. For example, a sunbeam can move at any speed; you just need to place the screen on which it runs further away. SR "prohibits" only the transmission of information and energy at superluminal speed. And for the transfer of information, a signal is needed that propagates through space - the expansion of space itself has nothing to do with it. So, in our example with receding galaxies, everything is in order with the theory of relativity: they recede at superluminal speed only from the Earth observer, and relative to the surrounding space, their speed may even be zero.
