  • My go-to is to just beg them to play Kerbal Space Program

    They argue that, if the moon landing could be done way back then, with modern technology, it should be possible to quickly get back to the moon.

    In the 1960s, getting to the moon was the most important thing in the solar system. The Soviet Union and the US spent ungodly amounts of money and risked uncountable lives in this endeavor. We did the thing, and now we’ve done the thing. We aren’t willing to risk those lives or spend that money anymore. New missions have to be much, much cheaper and much, much safer.

    Technology has definitely improved, but there is a physical limit to the amount of energy that you can pull out of a given mass of kerosene and liquid oxygen. Getting to space hasn’t gotten any lighter, and fuel mass has always been the biggest hurdle. Again, play KSP. It will brand the tyranny of the rocket equation into your soul.

    They also argue NASA could have just reused the same designs as the Apollo missions if they actually went to the moon.

    They could, in the same way that we could start sending children underground to mine for coal again

    To summarise,

    a) Been there, done that. Anything new will involve sending more mass than the Apollo missions had to deal with. Tyranny of the rocket equation: more mass means more fuel means more thrusters means more mass means more fuel…

    b) I could do some research and come back, but there is no answer to this that will satisfy a moon landing denier, because any explanation would require a baseline understanding of chemistry and also trust in the institutions that examine these moon rocks.

    c) The answer to a also applies here







  • If ghosts were real, then I can think of a few people throughout history who would have been swarmed by them. Adolf Hitler would have approximately 13 million spirits haunting him by the end. Something like 100,000,000,000 humans have ever lived, and somehow all the ghosts are from culturally relevant time frames? For all the US civil war ghosts people have seen, you’d think there’d be orders of magnitude more native Americans haunting this place. Did the European colonists just make sure to let the Indigenous peoples finish all their business before hunting them to near extinction?
