OK...the in-movie assertation that this movie was an alternate timeline was both simple and brilliant, and I really enjoyed the movie. However, I do have a problem with two parts:
An alternate timeline wouldn't explain a difference in physics, Star Trek, or real world.
1: How in the living hell did that entire fleet warp out of Earth's orbit? What about a planets gravity well and all that?
2: The freefall jump from low orbit to the drill was pretty idiotic....they'd have burnt up when they entered the planet's atmosphere.
Any thoughts on these two items?
