  • There’s a difference between calculating the necessary tensile strength of a chain and calculating how much energy would be required to make a chain of that tensile strength. For example, if an undiscovered element is required, does that mean it would need to be generated from nothing, so to speak, with a particle accelerator? How much energy would that take for a cosmically large chain? Or are we to assume that a massive asteroid composed entirely of this miracle material will simply pass Earth closely by?


  • Generally speaking, thought experiments need to yield useful conclusions before they’re worth publishing. Even if your “mithril” could exist, this thought experiment doesn’t even cover the question of whether this system of chains would yield enough energy to justify the amount of energy that would be spent creating and maintaining this cosmic-scale mechanism. And wouldn’t the “biological organisms” be constantly spending colossal amounts of energy just to prevent these chains from ripping away from their anchor points?

    And not all types of energy are equal. Energy needs to useful. Even if this system could be created at an energy profit, how would we harness that energy towards useful ends? Would the energy be used to somehow boil water to turn a dynamo to generate electricity? Does enough water even exist on Earth to be put to that purpose? We can currently cause fusion reactions if we want to, but the problem is harnessing them towards useful purposes. We don’t need to invent an even bigger bomb.

    It’s a clever way to beat hotlinking: you can get the comic punchline by hotlinking, but if you want the red-button punchline or the tooltip punchline, you have to actually visit the website so that the creator gets some ad revenue.
