Factual error: A bottle of champagne in space rotates around its centre of mass, not the midpoint of its axis of symmetry.
Factual error: According to the laws of physics, a massive point source should exert the same amount of gravity on an object X distance away as a spherical object of constant density with radius less than X. It is stated in the movie that Soren's weapon uses "Trilithium," a substance described as a "Nuclear Inhibitor." Stars generate energy and light by way of Nuclear Fusion. That fusion is possible because the intense gravity causes the gasses in a star to compress and heat up. This is essentially fusion by friction. If Trilithium stops the fusion from occurring, all that would be left is a very large body of hydrogen and helium - That is to say, an oversized Brown Dwarf. It shouldn't have been able to alter the gravitational pull of anything since gravity is a function of mass and all the star's mass is still there.
Factual error: For the shock wave from the Veridian star to engulf Veridian III so quickly it would have reached the remains of the Enterprise-D (and survivors) so fast they would have no time to think about running.
Factual error: When the champagne bottle hits the ship, the liquid droplets change directions and drip off the ship, despite the ship being in a zero-gravity environment.
Answer: Vulcans do live that long (300+ years), but it is not Tuvok. For one, his ears and eyebrows are human, not Vulcan, for another, Voyager tells us he left Starfleet for over 40 years shortly after the Khitomer conference, which was before Enterprise-B entered service.
