So the energy they need to bring is the energy equivalent of the matter they would have needed to bring to get the same result.

Or an other way to see it : they have to annihilate two Mars planet to get enough energy to create gravity on the third one.

Yep, pretty much - but tourist from Earth will feel gravity just as at himo and gondola rides will be 100% authentic! ;-)

No wonder Aria is a perfect slice of life / healing series - any aggressive aliens or other evildoers don't stand a chance agains their rather low profile yet insanely high tech level! :)
