Come to it, though, since the mere presence of a Sphere pumping out its sphericity-waves will kill planets in the vicinity after long enough exposure, why didn't the Sphere Builders just skip the whole Xindi gimmick and drop a sphere half a light-year off of the Sun a couple centuries ago when they started pushing Spheres into the Delphic Expanse? It'd pretty well pre-empt not just the Federation and kill off Earth, but also would soon wipe out possible other antagonists like Vulcan and the Klingons.Apogeal Alpha01 said:
That it was a probe comes from Futureman and the Xindi council. I know it doesn't make sense to send a probe, or a prototype to strike the final blow at a target. Since it would have taken some time to destroy Earth cities with that weapon, you’d think it would have been accompanied by other ships to protect it from a counterattack, right?
Or was wiping out the forces that would have gathered from the murdered Delphic Expanse worlds all the more critical?
Drop a sphere in the vicinity of Earth and it could be destroyed by the combined power of dozens of Star ships. The Enterprise was alone. Once the weapon was perfected, it could be used on any world they chose to.
