Galactus can teleport entire galaxies, and he can detect planets that he wants to consume with his cosmic awareness (if I understand correctly). Why doesn't he just teleport planets to himself, or extract the energy from them with his cosmic telekinesis? This would make him never weakened, and almost unstoppable.
Why does he not do this? Could he even do this, or am I wrong? If I'm wrong, why?
Thanks guys :)
