Maybe after all the math is done by the more studious viewers in Lost Land, I'll post the ramifications of the calculations here, if a final consensus can be achieved. Then the larger questions will be, what did the missile have to travel through to get to Dan at the designated target, and why did the instruments on the ship see it arriving at the LZ before it actually got there?
TPTB also leave us to continue guessing about what kind of possible lensing or shielding effect is surrounding the island....an electrical shield?...a magnetic lens?...both combined?...or the ominous wormhole?...that caused the time differential. And, why did Dan the quizzical scientist think that the outcome was a bad thing, and not an interesting scientific condition? He was very specific with Frank about where to fly to get away from the island and back to the ship, as if it would be dangerous to diverge from the coordinates. TBD as usual!
Update: Over at Fishbiscuitland there is a mention of Time Dilation. I found a simple video of that on Youtube:
In a nutshell: A ship-to-ship laser pulse seems to take a certain amount of time to bounce back, as seen from the two ships. From the view of an asteroid that the ships are passing, the distance is longer, due to the distance traveled by the ships that bounce the pulse. Maybe this is why the missile took longer to get to Dan? This should please those who like to think that the island is moving somehow, so do I. Although you'd think that the ship-to-island path on the show would represent the ship-to-ship path in the video, so I still can't get my brain to understand it completely. Unless the moving island and the stationary ship are the two separate vantage points. Ah well, that's all I've gotten so far. Can anyone elaborate?
Also, Morelosthanu posted on The Lost Community blog (after Ellen found a science thread to a donut-space/Moebius strip thought), that a surrounding Moebius area of space could explain the one "flat" spot for escape via the critical coordinates that Dan stressed to Frank upon leaving the island, and that Ben gave to Michael. This could make getting into the island gravity-well a bit less tricky than getting out. Insertion into the Moebius ring might just involve getting swept into the space/time/gravity "current", but could still be "tricky" (turbulent?) as it was explained to Juliet. Though getting out of it would be more difficult, as in, veering off course could send you circling the island in the Moebius loop "walls" until you fell back into the island-space, like Dez did. So....how does this relate to the Dilation theory?? Further discussion is pending.
