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?
