They could certainly take advantage of it by destroying the royal family's ship and influencing the rebuilding, but actually moving two planets only one time is a bit much.
Well mother brain did cause something to fall into palma and hit it. In Gundam chars Counterattack, we see mass gundams stop Axis from hitting the Earth by pushing it away.. Maybe that applied? They did have machines..
Or maybe just moving the Noah caused fluctuations.
Either way the elliptical theory works but it makes the Earthmen look less sinister.
They woulda destroyed Palma and then Mota and like stated in PS IV, if Mota was destroyed, the PD would be free Xd Compendium states they wanted to rebirth the Pd. weee..
I think the Earthmen's technology was very superior to Algos.
Why didn't the Earthmen save Earth? Simple. They didn't care. Just like 80% of the people on this planet don't give a damn about the environment. When was the last time you tried to save the planet? Recycled everything you threw away? Walked instead of drove?
The Earthmen didn't save Earth because they had destroyed it with pollution and destruction. Coral did the same thing in PS Zero.
How long will Earth stay perfect? We ruin the environment every day. There is damage done already that we can't fix. In time our population will be too big, wars will come and maybe fleeing will be the only way.
Most of the world now is just like the Earthmen. We want to control everything and want everything. We don't give a damn about the planet or what we do to it. Companies don't care about where they dump their waste. Companies don't care about smog. People don't care.
Like the japanese pS 2 states, We want to control the world with scientific means. We want to clone, create and be gods. We won't realize our mistakes till we damage our planet too much.
Cuban Missile Crisis almost made a nuclear holocaust realistic and the Earth would have been even worse off than it is now.
