Comment on what really happened to the Titanic

  but nuclear armament is a far cry from Earth shattering!

  You forgot about Project Sundial

    Ideas are not the same as possibilities.

    Also, the Earth takes hits bigger than that. Even the Tonga eruption was about 10 megatons of energy.

    The Chicxulub impact is estimated to be around 100 trillion tons of tnt equivalent. 10000x bigger than Sundial was even proposed.

    Chicxulub did not shatter the Earth.

      Project Sundial wasn’t just theoretical. We had the ability, the materials, and the technical knowledge to build it. You know how you can absolutely verify that? We built it in thousands of different bombs rather than just one big one. If we had made a 10 gigaton device where it was supposed to be located in eastern California, or western Nevada, blowing that up would have created a massive crater that probably would have measured at least 30 miles in diameter, and all of the US would die in the first blast. The shockwave would circle the globe multiple dozens of times. This is a world ending bomb. Half the planet’s crust would be molten for decades if not centuries. 10 gigatons is about 1/4-1/5 the amount of energy that Theia imparted to Proto-Earth which created two moons for a very short period of time, and made the entire planet molten for another 1/4 billion years.

        lol no. It would not kill all of the US. At all. In any way. It would be 10000x smaller than Chicxulub. Which also did not instantly wipe off that large of an area.

      Project Sundial was 10 gigatons, so, 10,000 Tongas.

      I’m t was enough to ignite all of metropolitan FRANCE if detonated at an altitude of 45km.

      The earth would survive, sure, but I’m pretty sure there would be significant global effects.

        Well yea, it killed off the dinosaurs, who survived on the planet tens of thousands of times longer than humans. It was catastrophic.

        Still not Earth shattering, though.

    That was a fusion device though

  You’re not thinking big enough. ;)

    Nah, there’s literally not enough nukes or even fissile material to make an Earth-shattering bomb. It takes a lot of energy to shatter something the size of Earth.

      If you blow it up on the surface or in the atmosphere, sure. Blow up a 10 gigaton device, which we absolutely can make and have the materials to do so, buried as deep as you can possibly get it, so about 1.5-1.6 miles in the crust, and you’re gonna wreck a significant portion of a hemisphere.

        lol no. Genuinely, no. You are a clueless fool playing with numbers you cannot comprehend.

      Not enough fissile material on earth. With enough asteroid and planetary mining, and … ah never mind. You are probably still right. "Shattering means breaking apart and defeating earth’s gravity well.

      We’ll have to get started on antimatter bombs for the required energy density, I guess.

      • LurkingLuddite@piefed.social ⁨2⁩ ⁨weeks⁩ ago

        Correct. Even with perfect conversion of mass to energy, it would still take converting the mass equivalent of a 16+ km asteroid directly into energy.

        Even antimatter explosions are not anywhere near 100% efficient. They produce many subatomic particles with high energy. Much of the reaction will quickly (on the order of 1x10^-18 seconds) settle into neutrinos or electrons. About half of the energy would nigh-instantly convert to neutrinos. Neutrinos will not care even if they’re produced in the Earth’s core.

        Deep core mining is the real tech we need. Blow up a 10 gigaton device on the surface and you’ll melt a hemisphere of the upper layer of the crust, bury that baby 5,000 miles into the planet and blow it up? The Earth is gonna need help opening it’s ketchup bottles for a few billion years until it reforms.

    Maybe it was in a Vegetable Glycerin reference.
