Well they believe the X planet will collapse with Earth seeing as to how it's gotten closer. their theory of space interpreted in math would be delta s, x, y, z squared minus c squared delta t squared representing the separation between two points in spacetime, it's advanced but it all goes back to Einstein's hypothesis of relativity. They have a bunch of formulas and equations for wormholes as well, if you study this I'm sure it will be interesting.
