Here's my fix for the physics problems:
-- Get rid of the transporter. Impossible.
-- Get rid of warp drive. Trek-type warping is not possible.
-- Get rid of artificial gravity. Not possible (unless the ship is rotating).
-- Get rid of humanoid aliens. If there is intelligent life out there, there's probably a 0.000000000000000001% chance of it looking anything humanoid.
-- Get rid of all sound in space. Doesn't happen.
Oh, and solve the ship falling into the atmosphere due to gravity issue.
Hey, in for a penny, in for a pound. Let's get these things right, people!
