It is possible. You know why? It happened. Therefore, it must be possible. We can attempt to explain it in scientific terms, but we don't need to, because it does happen, therefore it can happen. Think of a sine wave and a cosine wave on the same graph. They are constantly being pulled out of the positive realm and into the negative realm. However, at least one is always in the positive. Think of the two waves as the Halo array's energy, think of all positive Y's as regular space and negative Y's as slipspace. This constant transition between slipspace and regular space could be just one of the many explanations. I could easily come up with more. But that's not important. It's not possible to move objects with one's mind. It's not possibly to go faster than light. What's possible is irrelevant because this is fiction. Halo is bound by the rules of Halo. Star Wars is bound by the rules of Star Wars. An American citizen who chews gum isn't breaking the law just because it's illegal in Singapore. A British woman who leaves her house alone isn't breaking the law just because it's illegal in Saudi Arabia. Halo breaking the normal laws of physics is irrelevant because Halo has separate laws of physics. You must be a moron if you can't comprehend this.
