It's accepted that the mind controls the body by electrical impulses between neurons and down the spine and along nerves, etc, which allows us to move an arm to pick something up. However, what stops us from using the same concept to pick something up without touching it?
My character can send out electrical impulses from his brain like the rest of us do. Except, instead of remaining within his body, affecting his movements only, the impulses could travel through the air, or whatever medium he's in, directed by him of course (like we can direct an impulse to our hand, not our leg when we want to pick something up). Then, he can move things around without physically touching them.
Distance would matter as it takes more energy to send an electrical impulse further away from you. Using this concept, he can also manipulate matter at the atomic level, removing an electron or neutron from the atom, like how we'd assemble Lego bricks. He can then manipulate matter, and light and other forms of energy. Whether he can interfere with the electrical impulses in other people's brains and read or change their thoughts, I have yet to decide. But basically, thanks to this, he can feel everything around him to the particulate level, just like we can feel what's happening to our bodies.
What possible problems could arise from something like this?
