I found the ultimate Earth defensive net!
It only takes 40480 years to build it! If you are using Erratic Time Factories! Divided by the number of Factories in use!
It requires roughly 3,073,949,180,215 TONS of Sunmetal.
But yes, upon hitting the big red button, we can plane-shift the planet.
(The earth is pretty much 152,424,712,660 Vast portions. Yes, it is BIG.)
