- The Death Star is a battle station the size of a small moon... but does it have it's own gravity?
We all know that gravity plating must be standard in a galaxy far far away but this was fun. And majorly disappointing.
Check out my video all about the science of the Death Star if you want to nerd out to some Star Wars science. • Star Wars: The Death S...
-- About Me --
I'm Abi, a phd student at the University of Oxford working in plasma acceleration. I love to get super nerdy about pop culture and find ways to explain complicated topics in physics. It's a nerd revolution and I'm here for it! - วิทยาศาสตร์และเทคโนโลยี
This is fun. But I would like to point out that their other ships have gravity. It would make more sense for the Death Star to just use the same tech as their other ships.
Boooooo
"All too easy."
That was nerdgastic 😂
I'm happy because I was certain before this video that the Death Star would implode on the force of its gravity. Possibly not! But now it's necessary to calculate the stresses on the support structure from the reactor producing 1g of acceleration...
Orientation is the trick...1. gravity would work from the center of the sphere, to the outer shell, so you'd stand parallel to the radius at your point on the surface. All of the floors within the Death Star would be spherical shells of slowly increasing radius. But the movie has the 2. gravity centered on the SOUTH POLE, and all the floors within the Death Star are planar, all geometrically normal to that south pole, and all the floors are parallel to each other. So it would seem that 1 is natural, while 2 must be artificial.
OMG. Energy! And I thought you were going to say it’s constantly accelerating😅
Your authority is accepted
You’re doing the Whills work here, thank you!
So… any time the laser is fired to destroy a whole planet, the station loses gravity or everyone at least feels significantly lighter?
Love this ! That you for posting.
My life is complete.
considering that in the historical documents provided by George Lucas et al, The people on the Death Star where also walking in a 90 degree angle to the "center of mass" to... but i was waiting so long for this information how light the Gravitational Influence of the Death Star would be... thank you very much
Its spherical shape is just feng shui.
My worry would be that if that 'core' were the gravity-well center, and people out near the surface are able to be at 1g - then people only a few miles out would be in trouble. ;)
The hypermatter maintenance crew are not having a good time 😬
You assume there is a core gravity generator, but the Death Star crew are not walking around on the surface, or on nested, spherical decks within. The decks in the Death Star are stacked, as in any ship or building, which assumes a source of gravity _below_ them. This would place a single gravity source at the "South pole" of the Death Star. Furthermore, the gravity effect would need to be directed, as otherwise it would project out into space at that part of the station and both effect navigation and draw other ships towards it.
In order for a gravitational constant to be provided on all decks there would have to be a directed gravity generator or generators for each deck (or perhaps every few decks) pointing "up" towards the "North pole" of the station.
The obvious solution is magical antigravity. But as a physics solution, mine is more ‘realistic’ and the deck orientation is completely wrong.
Trusting your hidden calculations, it’s actually good that the Death Star has almost no gravity of its own, in part because that means the entire sphere can be occupied by people, ships can come and go without fighting surface gravity, and the same sci fi fantasy gravity plating that’s in all SW ships can do its magic there, too. So the orientation of gravity aboard the whole battle station can be floors instead of some Escher-like sphere. I’m still curious about your mass but I liked your “solid steel” mass example, too.
Electro Magnets?
I did need that in my life
I would prefer the “magical/gravity plate” explanation because there are parallel floors on the DS, like an office building. If there is a gravity source in the center of the DS, then the floors would have to be spherical around that source which isn’t present in the DS blueprint that is presented in this video. Every interior scene of the DS seems to be more like an office building with the 1st floor at the South Pole & the “penthouse” at the North Pole.
I prefer mine because it’s a clever real world solution. There’s no ‘explanation’ to give for things that don’t exist
I mean, I've been surprised by how much gravity there is on tiny asteroids and comets based on the recent probes
Kugelblitz black hole at the center. Mass for size should work.
Perfect!
How many teaspoons of neutron star would be needed? If they kept it at the South Pole of the Death Star? I say South Pole because folks walking on the DS seem oriented North South rather than feet towards the core
Love this! I’ll be doing a similar one about the moon in moonfall so will check the d star numbers too.
They do? Since when?
What about the pull of the station when it jumps to a star system like Jedha or Scariff. If we had a small moon turn up all of a sudden wouldn't that be just as dangerous as having our moon suddenly vanish?
In fact, l did need to know this. And l will respect your authoritah 😁😝😜
Well...... as long as we are ignoring "It's not that kind of movie, kid." how fast would it have to spin to create the equivalent of 1G on the interior surface at the equator?
OK, before watching, I'm going to guess that because of the station being mostly void, negligible gravity on the surface. Of course, the closer to the center, the less gravity.
If it had its own gravity the decks would be arranged like the layers of an onion wouldn't they, whereas they are stacked vertically suggesting the same gravity generation tech used in other ships.
While you might be right about the orientation, I stand by my solution and maintain that George Lucas was wrong… 🫡
the people standing in the hangers are horizontal to the center of the death star. just sayin
Or how about the fuel is much much more dense than steel.
I'm going there...
Where do you put all the energy losses on the way to the laser cannon?
You would dump more energy inside the death star than on the target...
The laser takes 10^33 joules/s. The reactor powers the laser and the hyperdrive and some power will go to other systems around the ship. So the energy loss from 10^41 to 10^33 is fine.
@@popculturescientist You are still dumping more energy inside the Death Star than on the target...
(OK, the Hyperdrive has potential to dump it outside. Which begs the question what sort of equivalent gravity each other ship with a hyperdrive generates...)
If you generate 10^41 and 10^33 goes to the laser then that leaves 10^7 dumped on the way. CERN uses about 15x10^7 Watts to run the systems
@@popculturescientist That's not how exponents work. If you generate 10^41 and 10^33 goes to the laser, then you basically still have 10^41, maybe 10^40 depending on the number in front of the exponential multiplier.
If you want to subtract from the exponent, you have to divide. Consumption of power is subtraction, not division.
(To be fair, you briefly had me doubting there: I had to hack the equation into Excel to be completely sure...)
You are right! I have no idea why I divided! That’s just the ratio of power.
Well then there’s plenty of energy to maintain the gravity field while using the laser at the same time.
If you are going to argue about the energy containment, I don’t know what to tell you, it’s a spoof science theory about fiction. 🤷♀️
It does (not) if the writer says it does (not) .
Obviously it’s the force.
If star trek has an universal translator, how can they use an expression in a foreign language without it being translated too?
Not sure what your comment's doing on this video. But anyways, if they want to say something in another language, and have it stay in that language, they just say it with speech marks around it.
@@jamesc3505 air quotes, Or Victor Borge spoken punctuation?
@@terrylambert8149: Oh, I guess the universal translator should pick those up. I was just thinking say it how you normally say speech marks, though--like a comma, but with different inflection.
Try artificial gravity. Forbidden Planet uses it. Start Trek uses it. Battlestar Galactica used it. The Orville uses it.
It’s concerning that you think I’m not aware of the use of ‘artificial gravity’
@@popculturescientist Well, you didn't mention it. Perhaps we can have lunch together and discuss your interesting ideas.
I say ‘we can assume gravity plating or magic’
@@popculturescientist You're too good of a scientist to assume. Let's discuss it over linch.
While the calculations were interesting, I think I should point out that fiction doesn't tend to conform to reality. 👍😊
I don’t think anyone is in any danger of confusing this with reality.
@@popculturescientist Thanks for the reply, you would be surprised, there are some out there who reside in their mind, in a galaxy far far away.
This vid just randomly came up on my feed, so I took it a little out of context, after looking through some of your other content it makes more sense now, I just thought you had lost the plot a bit, but can see whee you are coming from now, prefer the serious stuff though, you have a good presentation manner about you.
I will enjoy watching more of you content.
All the best to you. 👍😊
