In theory there would be a point between the sphere's inner surface and the star at which gravity from the sphere and the star would neutralize each other. So it would be possible to float over the exact same spot of the sphere without "falling down". This cannot happen inside the atmosphere though, since every molecule that passes this zero gravity level would be pulled into the star.
That been said I'm sure those starships have some kind of anti-gravity device that keeps them from falling down.
yeah i would say if we take our space program into view or yes i dread to say this the second JJtrek film then ertial thrusters would be where that comes into play otherwise it would be like how airplanes or space shuttles fly in the atmosphere
I love it how the description of a new STF-looking PvE turns into a scientific debate whether or not star ships are capable of flying in the Dyson Sphere.
Of course there is artificial gravity given there is an actual atmosphere on the inside. Otherwise the sphere would have to turn itself and only a small band along the equator would be habitable. But then why building a hollow sphere instead of a ringworld?
There's nothing like "short range gravity" though. The force of gravity always decrases with range according to Newton's law of universal gravitation.
Once you start discussing what is and is not possible it's a good idea to use the up to date stuff. General relativity models gravity as bent spacetime, which we use all the time for warp travel. "Short range gravity" involves a more complex bend than pushing 'down' using matter and allowing space to bend naturally, but is not necessarily impossible.
Edit: 'Trek artificial gravity inside ships requires a linear slope terminating at the hull, now that is rather complicated to achieve.
