I was thinking today about the Death Stars in Ep 4 and 6. Would an object like a Death Star have a gravitational field affecting other objects in space? I am uncertain, I mean they would have to have gravity in order to move about walking.
Thanx,

If something has matter, it also has mass/gravity. Something the size of a deathstar would definitely have a comparable gravity well to a similar sized asteroid.
As for the gravity on the station itself, that is through artificial gravity (also used on nearly every spaxe vessel in Star Wars.)
Yeah, I imagine the maintenance crew would have a hell of a time trying to keep the Death Star's outer hull clean. It would naturally collect space dust and debris, due to the Death Star's gravity.
All mass exerts a gravitational force proportional to it's mass. If the Death Star had a mass the same as a moon, both would have the same gravitational field.

True.....but pilots dont blow moons to smaithareens.... Not so true with imperial death stars...
The answer to the gravitional pull of a death star....is who cares?, a couple of topedoes makes the question irrelevant, and turns it into...........just HOW many magatons was that just got blown to hell ????

It does NOT have a gravitational field. It's NOT a planet, it's a DEATH STAR! Saying the Death Star has a gravitational field is like saying you can't successfully freeze a human in carbonite or the Force isn't real.

Even you have a gravitational field. It most certainly would.
Gravity is probably one of, if not the, weakest forces in the universe... but it is still a force. As big as the death star was, and with many components being high density materials, even with a lot of hollow space I'd imagine the gravitational pull to be quite noticeable.

The Death Star would be similar to a sheet of Styrofoam vs a sheet of solid steel of the same size.
yes, the mass of the Death Star would make a gravity field of its own. But, no where near strong enough for walking about. So, as all other Star Wars/Star Trek/Stargate space ships, artificial gravity is deployed.
And, I would expect that, with artificial gravity, you could in fact cancel out any naturally created by the mass, if there was a reason to.
If Darth Vader and Emperor Palpatine don't want a gravitational field, there won't be one. Never underestimate the power of the dark side, young padawan.
It WONT have its own gravity. It acts like theres gravity by rotating or spinning. Down will always be towards the outside from the center. The ISS has no gravity despite its size because it DONT spin. No matter how much bigger they add on, it still will not generate gravity.

HI all
Yep. How could I have forgotten something so simple, lol....

The ISS has NO (none) kind of gravity at all. Everything on it or in it freefalls/ floats. To have even artificial gravity it would have to constantly rotate around an axis. Even that would not be 'gravity'...it would be centrifugal force artificially simulating gravity by making ' down' the outside of the vehicle meaning anything that falls inside it would fall toward the outside walls. It wouldnt make any difference with mass...the ISS could be 5,000 miles across and still would not have its own gravity ... unless it was rotating. For one thing, if it DID produce its own gravity, all the space junk in orbit near it would be attracted to and sticking to it.
So much for ME not knowing what Im talking about.

I to agree that Centrifugal force ( real science ) is not the same as artificial gravity ( science fiction ) but in reality the ISS does have *some* gravity. It may not be measurable by normal means, and you sure cant feel it as a human, but its there. Gravity is everywhere. How strong it is where you are is what is important.
I"m not sorry for hijacking this thread - GUYS! I need your help naming a force.It's not gravity, but there's some *force* out there... , Whenever I go outside without a shirt, women stick to me as if I'm magnetic. What do you call THAT? (woa, do you talk to you mother with that mouth?!?)
AT first, I thought it might have been the "Axe effect", but it happens even when I haven't used any sort of product.
I'm starting to get a little scared. and chafed. Can you pull a few off of me already?

All mass creates a gravitational pull.
All mass.
Does the ISS have mass?
What about a hypothetical Death Star? Any mass on it? Any at all?

Gah
theBDub curse... I am sorry that you have been stricken with this.
OK, I read a few articles on mass and gravity. According to what I understand everything, even light rays have 'mass' and everything that has mass affects everything else with some degree of gravity. So saying all mass has gravity is technically correct.. so,Ill go along with that. However they also state that most objects of mass produce such minute amounts of 'gravity', its not even measurable. So would a real Death Star have gravity to hold you to the floor, not likely. Of course the Death Star is really a fictional object...so it can have or do anything the writer wants it to. ISS does not have any MEASURABLE self sustaining gravity...not even enough to make a speck of rock be attracted to it.
"Facilitating the Death Star's realspace propulsion were a network of powerful ion engines that transformed reactor power into needed thrust. In order for the Death Star to be a deadly threat, it needed to be mobile. Using linked banks of 123 hyperdrive field generators tied into a single navigational matrix, the Death Star could travel across the Galaxy at superluminal velocities. The incredible energies harnessed by the station combined with its great mass gave the Death Star magnetic and artificial gravitational fields equal to those found on orbital bodies many times greater in size.
The Death Star's interior followed two orientations. Those areas closest to the surface were built with concentric decks with gravity oriented towards the Death Star's core. Past this shell of surface "sprawls", the Death Star's interior had stacked decks with gravity pointing toward the station's southern pole. " http://starwars.wikia.com/wiki/Death_Star
comparing the ISS to the DeathStar in mass is like comparing a rubber ducky to an aircraft carrier
the ISS has very little mass. I'd be surprised if it was heavier than a school bus. And, yes, the Death Star is smaller than our moon - which barely has enough gravity to keep you on the surface. So, in them regards - even the WIKI article falls short. The outter layers could not rely on natural gravity - unless the power system is ultra dense - which is entirely possible.
A lt of sci fi shows just use "artificial gravity" and don't really explain it. sometimes, I think it's better that way. Same way they have that "universal translator" so you don't spend the whole show/movie reading subtitles...

Its also comparing reality to fiction. I said no matter how big they could eventually make the ISS, it still would not have any gravity (measurable) produced by itself, even if it was 1,000 miles long. After reading up, I still stand by that. Since the Death Star is entirely fictional, it could be made of a material 10,000 times lighter than aluminum too, so maybe the moon size Death Star weighs in at 800 Earth pnds.

The UT is explained in several shows.. in different ways. ( in some, its just a fish ).
Not so much is this topic divided, lol. Here is another one, if you weigh more would gravity have to work less?
Thanx,
Ear-ick
Would gravity have to work less? Do you possibly mean, would you have to try more to stay off the ground? Gravity is a force that will provide a (relatively) constant acceleration on earth of 9.81m/s^2. So the work being done is the negligibly the same as long as you don't start talking about the minute differences between gravity forces on different elevations...
Work is defined as Force x Displacement. Force is mass times acceleration. So if you have more mass with the same acceleration, you will need more work to go the same displacement off the ground. But if you use the same amount of work as when you had less mass, you will create less displacement.
I have to leave work and don't have time to proofread because that statement was a little confusing. Hopefully it made sense... and I was right.
I can see the the topic has shifted slightly, but I remember they had a couple runs of the "howstuffworks" shows on the science channel about Star Wars. They explained the Death Star and Lightsabers and what would and wouldn't work about them in real life. I tried to find a video, but to no success

I was in complete agreement after reading your first two posts that you have no idea what you are talking about. Then I started reading this post and decided you do know something about what you are talking about.
But then you ****ed it up when you stated

"Of course the Death Star is really a fictional object"
So I'm back to YOU DON'T KNOW WHAT YOU ARE TALKING ABOUT!
