Time to get my geek on

I recently watched "Star Trek: First Contact" for the umpteenth time. In so doing, I once again noticed something that bothered me almost to the point of distraction.

First, a little summary. The enemy in this movie is The Borg, a race of cybernetic beings (of all species) that have no individuality and function as a collective unit. Their mission is to conquer Earth and assimilate mankind into their collective. The Federation gather (almost) every available starship to stop them, but are unable.

Violating direct orders to stay out of the battle, Capt. Picard -- himself once assimilated into the Borg collective -- leads the Enterprise into the battle where he takes command of the fleet and destroys the Borg ship.

Before the ship is destroyed, however, the Borg launch an escape pod on a direct course for Earth. This pod is equipped with some sort of time travel device and allows the Borg to travel back to April 4, 2063, the day before humanity makes first contact with an alien species. Their intent is to stop this first contact and assimilate Earth in the past in order to control the future. The Enterprise follows the Borg ship back in time in order to stop the Borg and preserve First Contact.

So, as the movie goes, the Borg gain control of part of the Enterprise itself. One of the areas they control is the "deflector dish," which can be modified into a sort of satellite to communicate with the Borg that are on the other side of the galaxy in 2063.

In order to stop them, Capt. Picard, Lt. Worf, and Lt. Hawk attack the Borg modifying the deflector dish -- on the outside of the ship. To do this, the three don spacesuits and magnetic boots in order to walk on the hull.

Here is where the problem comes in. They are also carrying weapons with them -- phaser rifles, to be exact. At one point, all three men lay their rifles down on the hull. Can someone please explain to me how physics goes out the window here? The rifles do not float away as they should in a zero-gravity environment. They remain lying on the hull, where they are picked up by each man at one point or another.

Look, I can suspend disbelief enough to enjoy a good time travel movie. But when something simple like gravity is completely forgotten . . . well, let's just say I cannot make it so.
