4. Who Has The Terraforming Device?
This is a very important question that needs to be answered. At the end of the movie Lois Lane and the other scientists managed to send the Terraforming device back to the phantom zone. The only problem I have with this is that they only sent half of the whole device, sine the other half is still located somewhere around the world. Sure, that other half is completely turned into pieces and it's quite likely that it won't work again, however the important part is the entire technology of the whole thing. Something like that is way ahead of the technology we saw humans had on the film, and the fact that they can have access to said technology is something really troubling. It would be really interesting to see that someone managed to get the Terraforming device and that they used the technology of it in order to create a machine of similar capabilities. Who knows, maybe Lex Luthor might use something similar in Man of Steel 2.
