I did skip a lot of the sciency parts of the video, but seem to get the Spock theory about it traveling too fast so it must be from out of the solar system and it is from an older part of the universe based on its direction, so it must be old like 7.6 billion years.
I do not get the part of it changing trajectory as stars and planets pull at it, but we know where it comes from. If this thing played pinball all over the universe being pulled about, wouldn't we only be able to guess where it can from last?
The too long didn't watch I got was that it is nothing much to see here and just another comet.
