I can't say that I know much about space, but I thought it was amusing when Clinton said, "...we have conquered space...," in a State of the Union address. Like our tiny forays outside earth's atmosphere are of any significance compared to the vastness of the universe.

I was discussing space and time travel once with a very intelligent student. He asked my opinion about all of it - I told him I didn't think it was possible (to travel through time or to distant solar systems) and explained why. He asked what college I had graduated from - I told him, but asked why he wanted to know. "So I know not to go there," he replied and walked away. It truly was hilarious.

I've always thought that "warp speed" would be awfully difficult to do. What about all the debris scattered in front of the path of the ship? How do you chart a course of that distance without encountering any rocks?
