Only when Lucas Flannery died by being blown up to a broken metal statue, did I realized that was cyberforming. But I wondered why his body didn't shrink (or just shrinked a little). I thought cyberforming anything not metalic would cause a "black hole effect" - reducing its size much since metals are usually the heaviest substance. (for instance, Iron is the most stable and easy-to-find metal in universe, it forms soem planets cores.) What if cyberforming the whole Earh? (It seems the spaceship in AOE beginning only cyberformed part of the Earth surface) Would the Earch shrink to a much smaller size?
Well the metal is Transformium, and we know so little about it. So it might convert organic material without any size difference. But Earth is way too small anyways. Our own sun is too small to become a black hole- it would need to be at least twice as large as it is now to even have a chance at becoming one.
Even if our sun did turn into a black hole, the orbits of the planets would not be disturbed. A black hole's mass is only that if the star that gave birth to it. A black hole's gravitational effects only really become dangerous once you get near the Event Horizon. That is the point of no return. In fact, you are more in danger from the high energy that a black hole will emit due to it's accretion disk before you even consider the Event Horizon.
No the mass of the matter on the surface of the earth that was cyberformed has in no way enough gravitational energy or pull to collapse in on itself then continue imploding.
