Doesn't the Bad Astronomer ever tire from being right all the time?
There was some astronomy in the movie, and if I remember correctly some bad astronomy, but unlike some people (wink wink) I do not take notes of bad astronomy during an otherwise rather enjoyable movie.
There was some BA, probably more Bad Physics but I don't remember the exact thing I wanted to remember about it. [img]/phpBB/images/smiles/icon_smile.gif[/img]
Oh yes, at some point he says they travel at superluminal speeds (quite clearly), yet afterwards he says the voyage took 7 years. He even compares his speeds of voyage to tachyons, mythical particles with an imaginary mass that would travel faster than light. From what I have read on tachyons it has been said that they would also travel back in time. [Conlusions should be drawn here].
This is getting very complicated, as it's two in the morning, I am tired and my brains are off-line. Could someone complete these thoughts for me please!
