If something sounds as implausible as you just made it sound, the explanation might be rather that they know more about the topic than you and that it is your numbers that are off.

You are welcome to try to find any other numbers, but all the evidence we have is that he is just making shit up as he goes along. Probably the most valuable things they could send back would be the vacuum Raptor engines they got there on, probably with their bells cut off.

  Sounds like you have an axe to grind. Think about solutions instead of problems, nobody is asking you for anything. If the physics permits something to happen, if there’s a will there’s a way. If you don’t have the will there is never a way.

    I don't know, I think appreciating the difficulty of getting to Mars is important, and puts things in a perspective that Elon Musk doesn't seem to respect when making these claims - which to be fair no successful hype man ever espoused a realistic perspective.

    Yes, let's make it personal. That always turns out well. If you can figure a way to get a million-person Mars colony together in under, say, a thousand years, with SpaceX hardware, go wild. Freeze and stack colonists like cordwood? Nobody said they have to be alive, right? They'd keep. Maybe somebody will figure out how to revive them, someday.

      > Probably you need to send ships in pairs, so they can be swung on a cable between ships' noses for centrifugal gravity. That way their bones don't dissolve on the way. Will 1/3g be enough? Nobody knows. But it had better be. I have some questions about this bit! 1.) Why would their bones dissolve? If bones aren’t used do they really just collapse? My hands don’t really experience gravity (I think!) and they are fine. 2.) Couldn’t you make some sort of exercise thingy that could simulate gravity? Thanks!

        1) Kind of: "One of the major obstacles to long-term space missions in the threat of severe bone loss in astronauts. In the microgravity environment of space, astronauts lose on average 1% to 2% of their bone mineral density every month. For a short-duration flight, bone loss is a fairly minor consequence. On a long-duration space flight, such as those planned for missions to Mars and beyond, bone loss can be a serious impediment. This loss may not hinder astronauts while they are in orbit, but upon return to Earth, their weakened bones will be fragile and at an increased risk of fractures. At this time, it is unknown whether this bone loss will eventually reach a plateau, or whether it will continue indefinitely." [1] 2) ISS astronauts spend a couple of hours every day exercising to keep the worst of the space-related medical issues at bay... but it's simply no substitute for real gravity.

Or maybe musk is just terminally full of shit? Autopilot has been "6 months away" since what, 2015?
