Super slow Prometheus trailer

@ around 10 55 into it , looks like Shaw ( i guess its shaw ) is a bit short on the jump ? and falls into the opening

Whoaaaa!!!! 6:54. Right when the light starts to move towards the table or whatever it is, you see it change in appearance very quickly. Maybe more evidence that the temple is appearing a certain way, but hides something underneath? The other evidence is the changing sequence Shaw mentions and which is shown clearly at regular speed. Thoughts?

Also, it appears that the ramming scene may not be associated with the ship falling out of the sky. If you watch closely, it at least appears that the outside wall of the derelict is being rammed and when you see the next shot of the ship falling out of the sky, it looks like the inside of ring shape was damaged.

I've noticed on the slow IMAX version trailer, that when you see the valley that the Prometheus is landing in you can see the large mound where they eventually enter. However, if you look more closely there are 4 or 5 more similar mounds all following in a straight line into the distance. Makes things more intriguing as far as the history of the alien planet is concerned and what remains in those mounds. Is it the same ship/aliens or something else and could it be used/featured in a possible sequel?
