    Here's a fun thought experiment: Imagine a box in front of you, a cube with ~3 feet on each side. Filled with TNT, that box would weigh about 1 ton. If you gave everyone on the planet 1 ton of TNT, that is about the same energy equivalent contained in the global nuclear arsenal.

        (I quick-estimated global megatonnage to be around 6,000-8,000 Mt of TNT, and at 7.5 billion people, that is basically ~1 ton per person. A metric ton of TNT should basically fit into a cube with sides of 2.8 feet.)

        Ok, I like where this is going... do you need my address to mail out my box and do you think it’s safe to store in my garage, it can get pretty hot there in the summer.

        How large have to be an object falling on earth to have same energy as all the nuclear arsenals? I imagine some 100km comet with right speed would do the job?

        It depends on the impact velocity. Typical velocity for asteroid impacts is ~17 km/s. 7 Gt TNT equivalent => ~650 m imactor (density 1,500 kg/m^3). Typical velocity for comet impacts is ~51 km/s. 7 Gt equivalent => ~450 m impactor (density 500 kg/m^3).

        Total energy is not the only relevant quantity when comparing impact and nuclear weapons effects. If you want approximate analysis of detailed impact effects; https://impact.ese.ic.ac.uk/ImpactEarth/cgi-bin … is one place to start.

        Thanks! I really overestimate it. Lol 100km. We are so weak in nuclear energy compared to the celestial objects energy that could fall on us.

        You want SI? The SI unit of energy is the joule. So imagine 4 billion joules for every person on the planet. That is about the same energy contained in the global nuclear arsenal. (Not to be confused with 1 million Juuls per person, which is also about the same energy.)
