• What would it take to destroy Earth?

    It may be a staple of sci-fi movies, but it’s a lot harder to destroy Earth than you think.

    As shown in this video from Second Thought, it’s essentially impossible for us humans to build anything that could destroy Earth. That’s because the Earth’s Gravitational Binding Energy, the gravity that keeps all of Earth’s matter together, is really strong.

    The current binding energy of Earth is 2.24 x 10^32 joules. All of the nuclear bombs on Earth are only have the force of 2.67 x 10^19 joules. It’d be impossible to build the one quadrillion bombs needed to do the job.

    Even antimatter, which is exponentially more destructive than nuclear weapons, would take us far too long to make. We would require a greater amount of antimatter than we could ever possibly construct.

    Our best hope for blowing up the world is a fast moving asteroid, traveling 90% of the speed of light, which is extremely unlikely. Otherwise, Earth is here to stay.
