It has been well established in the Stargate universe that anything entering the gate will exit on the other side with the same velocity (speed and direction) as it entered.
In the opening scene of Stargate Universe, as the various people are evacuating from Icarus Base to Destiny, they come flying through like they've been launched from a catapult. Yet even if they were running as fast as they could into the source gate, they should not have come flying out the other side.
Is there any explanation for why they came shooting and tumbling out of the gate on the Destiny, or was this most likely just a case of the director wanting to make it look all "dramatic"?
