How can gravity exist in the space ships in Star Wars?

Answer 1

Presuming you mean real space ships operating in a zero-gravity environment and not just fake spaceships on a film set? Funkymonk is right, gentle accelleration followed by a turn-over mid trip and an equal dceleration would create a sensation of 'gravity' through the soles of the feet.

Alternatively, in (say) a orbital space station, the interplay of centripetal and centrifugal forces created by spinning a structure, with its occupants, about its axis much like in the opening sequences of the film 2001, will create a sensation of gravity (tricky concept, very hard to understand ... serious maths involved) . A large diameter structure spinning slowly would produce the best effect.

Muscle wasting resulting from long periods in zero gravity is a major impediment to long space journeys, the gravity problem is one that needs to be resolved so that cosmonaughts can survive back in earth gravity once they return.

Answer 2

The ship needs to contain an inner "drum" within the outer shell which rotates. Einstein showed via general relativity that acceleration and gravity are equivalent. The rotating drum will accelerate the passengers to the edges of the drum. From their perspective they will not be aware they are rotating (if they cannot see the stars through the window), only that a force is acting downwards on them, in exactly the same way as gravity.

Answer 3

Gravity is generated by bodies, but is comparitivly week compared to other, electromagnetic, types of energy. After all, an entire planet has gone into making our gravity and I can overcome it with simple muscles.

String theory sugests that gravity is week because it exists in another dimension to ours and the effects we observe are considerably weeker than those experienced in gravities home dimension.

If you could find a way to overcome the barrier, so that the normal gravity of your deck plates were in force.........

Another option is, rather than having your decks running horizontally, place them vertically so that the effects of forward acceleration push the crew onto the decks. You would need to maintain 1g of constant accelleration to do this. Once you have reached turnover, halfway along your journey, reverse the ships facing so that the nose points backwards. Now apply the brakes so that the ships slowing down produces 1g of deceleration which will again push the crew onto their deck.

Answer 4

It's called Science Fiction, and specifically it's called artificial gravity - when we know how to actually do it, we'll install it on the shuttle and the ISS. You can see the same phenomenon on ANY Sci-Fi set in space - it keeps the production costs WAY down to pretend artificial gravity exists. No way could Star Trek run as long as it did without it.

Answer 5

I think you also have to ask how the spaceships make such quick dogfighting manoeuvres between other spaceships when there are no exterior forces acting upon them? You would need gigantic thrustors all over the ship in order to overcome the momentum. Not that I really care about it because I think the Star Wars films are amazing.

Answer 6

It can't - except by suspension of disbelief! The only practical way shown in SF so far was in 2001, 2010 and Babylon 5 where all or part of the ship or station rotated.

Answer 7

i cant believe you are talking about star wars and only worriedd about the gravity. what about all the talking aliens?

but back to gravity. anything can happen in the movies.

Answer 8

the fact it was made in a big shed somewhere on filming set maybe ?

perhaps G.Lucas actually built massive space ships and AntiGrav ?

:¬)

Answer 9

artificial gravity dude ... and its abt a specific frequency .. attained by the sheip by rotatiin its self around itself... it got some specific value ... and abt the star wars ... hmmm its a movie dude ... anything can happen .. :P

Answer 10

Artificial gravity...it's theoretical
