Correct. The nuclear pile is it's own fuel. It doesn't need an oxidizer. Nuclear weapons would work in a vacuum.

[Anonymous No.]

>>5986789
Yes it works, it doesn't rely on air, although with air there would be more fire and impact, without it, a nuke is pretty lame.

Not that guy but I thought the fire had a pretty important role in the destruction. Like extremely high temperatures and all

Waves require a medium to propogate in. Shockwaves can't form when there's no air.

[Anonymous No.]

>>5986892

In a nuclear blast, most of the destruction is done by the blast wave and pressure. It's a massive wall of invisible death the flattens everything it hits.

Picture related. US nuclear airburst(as in it never hit the ground) test. It's the blast wave annihilating a house.

[Anonymous No.]

>>5986903
Shockwaves are a secondary effect, the primary blast can still be sufficiently lethal on its own. One MIRV and then 2.5 years later we'll have wal-mart and mcdonalds all over the place there as well as lunar bunnygirl cafes for earth tourists.

[Anonymous No.]

>>5986892

With a nuke it's not "fire" really, it's more like a little tiny sun happening next to your head. Without air there would be no giant shockwave, true, but the key is that the heat generated is still massive.

Maybe this is getting too detailed but I'm dubious that a nuke could detonate properly in a vacuum... What initiates the fission is conventional explosives compressing a mass of plutonium to supercritical levels. If those conventional explosives fizzle from no oxygen, no big boom

The bomb itself could be designed with its own oxygen supply for combustion; it wouldn't need to draw it from outside.

Watch the video of it- in your picture the top-right frame is where the blast wave hasn't hit yet, but the heat is fucking boiling the paint off the front of the house.

I'm not saying that the shockwave isn't devastating as well, but heat that severe? That's some equally serious shit that could cook you real good.

I've always wondered, whats that black smoke that appears just before the house is blasted away? Is it the paint or moisture vaporizing off the front of the house?

Thermal radiation of a nuke blast: 40 - 50%
The heat is intense, but short lived. And a shadow is created behind walls and other such barriers. Normally, the shock wave would flatten said walls, but in a vacuum... The heat would normally start fires but without oxygen, that wouldn't happen. At least, we'd get ionizing radiation within 4 miles of the blast center.

All in all, you wouldn't be able to kill lots of people quickly, but they'd get radiation poisoning.

Energy will still dissipate in space. It would actually be even more dangerous. The energy released by the bomb will still be there, vaporizing anything in the direct blast zone, and instead of shockwaves, everything in the immediate area will be propelled away at lethal speeds. Effectively making the nuke into a frag grenade of epic proportions.

If this weren't enough, the radiation itself is also still there and will spread much more cleanly.

Even further, the EMP generated in space is much larger.

For reference, the US detonated a bomb in orbit and the blast was enough to disturb surface waves on the planet. Yes, the energy from the bomb hit the earth and disturbed the moons gravitational pull temporarily.

Earth was winning the war.

They just couldn't find the Lunar Capital.

Enhanced radiation weapons (neutron bombs) rely far less on the explosive effects; their blast yield is about 1/10 normal because they release the neutrons instead of containing them for a better chain reaction.

But then things get irradiated and die a frighteningly horrible death. People even get sick then seem to recover for a while, but permanently missing important functions they will die slowly without.

Yes, and? Starfish prime was done in the thermosphere, just slightly below where most satellites orbit. The thermosphere is in the vacuum, so for the purpose of this argument, it's a close enough alternative to a space blast.

[Anonymous No.]

>>5986990
The radiation thing, yeah. Gamma waves are gonna charge the shit of of you without air (atmosphere) to protect you.
I guess it all ends up being a question of how the energy acts on its surrounding - the sun, for example, burns the area within its proximity to temperatures that can turn steel into air. It doesn't really propel planets away from itself (there's no real kinetic force there from the constant "combustion"). It also gives off light, which is the obvious source of energy.
So I guess if a nuke goes off in space, a good radius around it will burn to ashes (literally), and everything in an even larger radius gets cancer.

Goddamit, atmosphere means that it's not a vacuum. Go back to elementary school.

[Anonymous No.]

>>5987054

At what point is it "not a vacuum"? 1 trillion times lower density than sea level? 1 quadrillion? If you don't declare a cutoff somewhere, the entire universe is the Earth's atmosphere.

[Anonymous No.]

>>5987054

I suggest you go back to school. The thermosphere is where the atmosphere ends. There's no oxygen. How do vehicles that go that high not be burned by the gas up there? Because it's in the vacuum and the atoms can't transfer heat. This is where the ISS orbits.

Christ, you're fucking retarded.

The exosphere is where the atmosphere ends. Vacuum of outer space exists outside of that. We're examining the surface of the moon here, for practical purposes, a vacuum.

We're arguing about whether high altitude nukes will create waves in Earth's sea. First, you need to show some proof that there were waves generated.

If you can, my argument would be that the explosion was in the atmosphere, meaning it is NOT a vacuum, and there is a medium for waves to propagate. In anycase, I'm suspicious of whether there were waves, since the blast was so high up.

The US DOD itself notes "significant magnetic field disturbances and earth currents".

Go check their report if you don't believe me.

>The exosphere is where the atmosphere ends

No, the exosphere is space. The space around earth, to be specific. Christ, the word itself says this. "Outer Sphere".

Yes, it's an outer sphere, of gases. Stop struggling.

[Anonymous No.]

Gas? In space? Why I never!
Why, there's four fucking hydrogen(this is also the only thing in the exosphere, by the way) nebulae just outside our solar system. I guess our atmosphere is huge!

You're fucking dumb as a brick, aren't you?
Hell, even in your Wikipedia article.

Oh for fuck's sakes, an earth(telluric) current is electric, not a real seawave. Kinda expected, since it's an EMP.
