i didnt watch this vid, but saw a great one awhile back. can someone explain this to me. Im no genius! i dont know much about the havens other than what i learned in school. i remember that a comet like haley's comet that has an orbit around a sun will speed up as it gets closer to that sun, right? If the basis for this planet x is that they found something in 1984 that was 50 millions miles away and something in 1992 that was 7 millions miles away and today its 2008. Shouldnt it be here by now.....or at least close enough we can see it with the hubble telescope. so then, why did it slow down and then why would it speed up to be here by 2012. Why wouldnt we be able to see something thats only 4 years away from us? any thoughts?
