No, no, no, you are all wrong.

Back in the day, the summer of 1666 to be precise, an apple fell on Sir Isaac Newton's head. This apple essentially let Newton to create the law of Gravity. However, in the future (these next words are backed up by Science, and other things you can't argue with) the black star ship, when speeding through intergalactic nebulae, actually caused a retraction of the GF only in apples (Gravitational Field). This retraction leads to the inconsistencies we see with said falling apple. You see, young Crannick was just trying to reproduce this simple experiment of his beloved Newton, when it all went terribly wrong. He hadn't taken into consideration the traveling ship, and is now trapped in a constant sense of fear due to an apple that just wont fall down.

I honestly feel bad for the poor guy.
