My version of Death Star 3. I know there's Starkiller base, but it's not mobile.

And I'll get this over with right away, 120km in diameter, like the first Death Star depending on your references.

First off, I typed this thing about Death Star 3 before the D23 Rise of Skywalker trailer came out, and I'd like to say something about it.

A YouTube channel called Generation Tech may have partially solved the mystery of Rey's parents.

She's actually a clone.

And near the end of the trailer, it seems as though she's a Sith. But my guess is Rey is a clone of a dead Sith lord, and is on the side of light because of her friendship with F1NN.

Think the opposite of Star Trek: Nemesis.

Anyways, onto Death Star 3, instead of blowing up a planet using kyber crystals and a big ass laser weapon that somehow violates the laws of conservation of energy, it destroys a planet that's something out of Star Trek -- turn off the planet's gravity.

So what?

The people will float off, the atmosphere bleeds away, how does it destroy the planet itself? Or a moon since Yavin 4 will be mentioned, but first the sake of not over typing, overthinking, or being so damn nitpicky, I'll just say planet.

If planets like Alderaan and Yavin 4 are like Earth with a molten core, then the planet would self-destruct like the Genesis planet from Star Trek 3: The Search For Spock.

The Earth's inner core is a solid iron-nickel alloy and may have a temperature of up to 7200°C -- which would be past its boiling point at about 2862°C for iron, 2732°C for nickel. And measures 2440 km in diameter.

The outer core is a liquid iron-nickel alloy 2400km thick, and at a temperature of between 2700°C and 2430°C in its outer regions, 3730°C and 7730°C in its inner regions -- also past the boiling point in the inner regions.

But if they're past their boiling points, what keeps them solid and liquid?

My theory, gravity. Since the Earth is so massive -- 5.972x10^24 kg to be exact, then the gravity from the total mass of the Earth pulls down the mantle compressing the core into its solid and liquid states.

But if the gravity were turned off, then there would be no force to compress the cores into their states. And as you know about Bernoulli's principle -- without knowing his name, high pressure core wants to travel to the low pressure of space.

And since the Earth's crust is between 5km-70km out of a diameter of 12,742km, the crust ain't holding that much pressure back. And without gravity, the mantle would still be pushed outwards by the expanding core which through inertia blows up the planet.

As you know, the Interdictor class star destroyer used gravity well generators to form "mass shadows" to interfere with hyperdrives of escaping ships.

With Death Star 3, the core of the planet killer is a black hole inside a spherical asteroid. It makes sense to have a massive gravity source to cancel out a planet's -- especially at 5x10^20kg that would allow for natural gravity for the station at just under 1G near the surface. That sounds big except that's only 0.68% the moon's mass.

The big dish there somehow siphons the gravity waves from the black hole, phase shifts it into anti-gravity waves or whatever and beams those anti-gravity waves to the victim planet, cancelling out gravity and the planet explodes from its own core pressure.

The small structures on the surface are actually strategically placed outposts that -- I would like to say they're as big as a super star destroyer if not for conflicting references. Anyways those structures are 8.5km in diameter with their own anti-starship weapons and their own fusion reactor to power them. But their anti-fighter guns are only effective if they're in range from the station's curvature.

There are also landing zones for imperial star destroyers.

The station has massive fusion thrust engines, but they are only for yaw, pitch and roll because the station's core being so massive that the station itself has to maneuver around it.

So no Wandering Earth (2019) here.

In fact the only real mode of propulsion it has is the hyperdrive, and that's based on the heart shaped Lazar warp drive from this post:

www.deviantart.com/newdivide17…

Using the antenna on the dish for where the heart curves meet. And the core can help with the generation of gravity waves needed to do whatever for the station to move.

Basically at warp, the station flies backwards. Which is useful since after blowing up Alderaan -- where it was still genocide despite being a legit military target, you don't want to be in the way of the incoming debris.

And those mechanisms on the opposite side of the station are the gravity wave drives that forms the point of the warp drive's "heart".

Plus at sublight speeds, it runs on pure momentum. It needs the Lazar warp drive to move even at sublight speeds.

So the station spins around the black hole, aims, fires, and moves off via warp drive before the debris damages the station.

How the station gets anywhere -- Alderaan, Skarif, Yavin 4 -- is a predetermined course where at the right moment and angle, the station makes a warp jump and comes out at the right point ready to strike.

But because of that right moment thing also means it has to orbit Yavin with its current momentum in order to reach the 4th moon. So Death Star 3 has a limited window to strike.

Despite having natural gravity, the station doesn't have an atmosphere since the atmosphere can be as thick as 480km on Earth even though most of it is within 16km of the surface. An atmosphere can work, but not with the fusion engines on the surface, and I don't want the station to start looking like Unicron when the weapon and thrusters need to stay outside of the atmosphere.

Besides, being in a vacuum helps ships with poor aerodynamics to take off due to the lack of atmospheric drag -- especially if you shoot TIE fighters out of a BSG style launcher at 12km/s, and later retrieved by a landing capable carrier.

And the TIE fighters can stay over the surface by essentially orbiting -- hence the need for WWII style dog fights. Another thing they probably couldn't do effectively in an atmosphere.

Realistically, the anti-gravity wave gun doesn't affect the entire planet, it probably only affects an area about 1000km in diameter and blows up the planet like popping a balloon.

Turn off the gravity in that area just over the core, that area and 3000km down would be weightless and cannot prevent the core from expanding.

The core pushes up the mantle becoming a super volcano style disaster as the released mantle can easily rain death and destruction over hundreds of kilometres. The rushing fluid fractures the crust along its thinnest points for thousands of kilometres, and the mantle still under the crust moves in to fill the gap due to the escaping mantle. And less mantle means less pressure to keep the core stable, and the planet goes kaboom -- probably more over their ring of fire if they have one.

And betting the planet will explode more like the way Krypton did on Man Of Steel (2013) than the way Alderaan did on Star Wars (1977).

I was going to give it a glossy black surface due it being covered in solar panels, but chose against it. But it might have made the station harder to see if not for the main weapon and surface bases.

But now for the important question, how do you blow up this Death Star?

Despite contemporary belief, the first Death Star's thermal exhaust port was actually FAR from unprotected as there were surface turbolasers, it was ray shielded AND hard to bullseye as the first attempt to hit it failed, and Luke apparently succeeded by using the force to steer the torpedoes in. Something EC Henry pointed out:

youtu.be/-CNEbzgYMXs

Plus it was unnecessary to have Galen Erso to have provided a convenient weakness to the battlestation as a technological monstrosity that's 120km in diameter would have a few oversights.

And as we found out, hyper ramming is totally impractical, and Vice Admiral Holdo was damned lucky to even hit the Supremacy in the first place -- let alone bisecting it due to the very tight precision needed, and the Rebels didn't have a ship twice as big as a Star Destroyer at their disposal like the Raddus.

And if they were extremely lucky enough to score a bullseye with a 3438m long ship they can spare, and able to travel through that much rock, the core was a black hole at 500,000,000,000,000,000 metric tonnes compact onto the size smaller than the period at the end of this sentence.

And it would need to be this heavy to generate those gravity waves needed for the planet killing weapon, and produce about 1G natural gravity for a station.

And before you ask, the station is 30km thick, and the G-forces would only be about 3Gs on its inner surface.

BUT because it is a black hole, that means it needs to be contained to keep it at the station's centre. And if say a containment generator were to be knocked out because of a proton torpedo fell into the generator's thermal exhaust port (Galen Erso?), then the black hole could shift -- or rather any part of the station could shift towards the black hole which not only would knock out the primary weapon, but would tear apart the station.

Billions of tonnes of rock would already start to fall into the singularity and be shredded into energy and blasted out of the poles blowing up the station.

Meaning no Praxis effect from it, and it would be a slow death like Starkiller base.

I did some quick research and found a black hole can remain stable as light as 10^12kg, and explode within a second at 10^15kg.

So let's assume that with Death Star 3's black hole being artificial, it's unstable and needs what Star Trek: Voyager calls an anti-thoron field to keep it stable. And if a proton torpedo damages it or knocks it out thanks to an exposed thermal exhaust port, the black hole will vaporize the station since the black hole would explode with a force of 1.17x10^16 megatons.

Thankfully for Yavin 4, that's only ~10% the energy needed to blow up a planet, and the Death Star was still pretty far away from Yavin 4. But unfortunately for the moon of Endor with the station being in orbit, it could have a significant environmental impact -- I don't know.

And though Death Star 3's asteroid is 120km in diameter, the largest known one in our asteroid belt named Vesta is 530km across.

So finding one for the Death Star in theory would be easy. Hollowing it out and putting it around an artificial black hole would be hard -- especially making the black hole in the first place.

Unless they captured a sizable black hole in that one star system that's riddled with black holes and an asteroid to house around it.

And if it's natural and stable, then so much for that idea. BUT the weapon siphoning off gravity waves might make the black hole unstable and still needs the anti-thoron field to keep it stable or else the station will explode.

But Death Star 3's destruction probably won't be instantaneous, but more like on Independence Day (1996) where the weapon powers up, then the damage takes over like Indiana Jones putting that rock in one of the tank's side gun on Indiana Jones And The Last Crusade (1989).

The main weapon fires, the planet's destruction is not instantaneous, the containment field ruptures before any real damage to the planet is done, Death Star 3 explodes.

Once again it may explode like it did on Star Wars (1977), or it may explode like Krypton on Man Of Steel (2013).
