Okay, so... everyone knew about this Hud-fa-dyd thingy, while Mo was still flipping through his book looking for the answer. His shoulder was hurting. Like... just all of a sudden. And the book was annoying him with it's stupid pages and how the words were all cross-wise and UGH.

He had to put on his glasses in class, which Mo did NOT like to do.

Might as well swing at this question from another direction. "The Hubble Space Telescope is this amazingly high powered telescope that sits low in Earth's orbit and takes deep space photographs." He had to pause to think about that. Maybe he wanted to learn to take deep space photographs. Question: did he have to be in low orbit?

"Anyway, the Hubble telescope took pictures of the Hubble Ultra-Deep Field over 80 years ago... although it's funny because it was looking back at those galaxies and things as they looked 13 billion years ago. Which, you know... THAT is some gray haired galaxies." Also, speaking of gray hair, why hadn't these kids heard of HAIR DYE? It did Mo's hair good.
