There was a time flash right before Juliet detonated the bomb by Eli in Red

My theory suggests that there was a time flash immediately before Juliet detonated the bomb, but that the bomb did in fact go off.

We know that somehow our Losties from 1977 were sent to 2007. However, at the same time, it appears that the bomb worked since we are seeing an alternate time line, and Miles claims that Juliet said "it worked".

So far, I have heard many theories suggesting that the bomb or incident somehow sent them to 2007, but I propose something else.

What if the wheel was turned a the same time Juliet was striking the bomb with the rock? The outcome would be:

(1) Losties time flashing from 1977 to 2007

(2) The bomb worked, but didn't kill our Losties in 1977 as they flashed immediately before it exploded

Now we have both an alternate timeline, as well as "whatever happened happened" at the same time. And who turned the wheel? My guess is Eloise Hawking, since we know she left the island at some point.

Let me know what you think.
