    Asteroid capture through encapsulation

    this research paper on asteroid capture through encapsulation and pneumatics (stabilizing the asteroid through spraying it with gas) is super cool; I watched one of the authors give the presentation and it's very compelling....

    As cities like Austin cater to coastal transplants, their unique culture gets diluted, becoming more generic. Is cultural entropy inevitable, or is there a counterforce?

    The canary in the coal mine for me is the yuppie coffee shop (which admittedly I love). When you're in one of these shops - the ones with the $6 non-dairy cappuccinos, gorumet chocolate chip cookies topped with malden salt, in a room with lots of wood accents and pothos plants overflowing from their shelves, there's no way to tell if you're in Austin, or Williasmburg, or the mission district of SF or Shoreditch in London. 

    While the internet enable infinte diversity and microcommunities, physical spaces seems to be converging toward a monoculture. I imagine fueled by things like increased global travel and social media.

    I fully agree; and your last sentence has me brainstorming potential countervailing forces. I'm going to throw them out without yet knowing if I actually think they'll move the needle at all: space colonization: when it takes 22 minutes for light to travel from Mars to Earth, I...

    Mars feels like a really important backup plan. If there’s even a small chance that Earth is fucked from global warming, we need to be able to go to Mars. I heard a cool concept that we can basically artificially create global warming on Mars by putting greenhouse gases in the atmosphere.

    Unless it’s life or death, I personally wouldn’t move to a planet with less than a million people on it (imagine Austin is the entire world, that feels like the bare minimum for me).

    How much money and time would it take to get a million people to Mars?

    For me Venus sounds slightly more appealing, particularly bc in my mind if something cracks on Mars I'm dead, whereas it sounds like in the clouds of Venus I'll have a long time before I'm atmospherically poisoned....

    I can envision a whole wave of settlers going to Mars or Venus to be The only/first X on the whole planet.

    amazing, I’d never heard of this! Venus is the hottest planet, but I agree cloud city with a slight backup plan feels way better than underground. Venus is 10.65 million miles closer according to Google; is it easier or harder to get to in terms of slingshotting or space debris...

    I’m in favor of us having a backup plan, but I think it should be Venus actually. There are good studies about this. You can build floating cloud cities in Venus, which float at precisely the altitude where the pressure is about 1 atm and the temperatures are even sometimes what...

    What will the future literally look like? This idea comes from watching Mad Men- seeing smoking and drinking freely at the office for example, and my brother once pointing out that if a show or movie ever wanted to make it really clear that it was set in the 1990’s, all they’d have to do is have multiple people driving Saturn cars.

    So here are a few of what I think (hope) the future will literally look like:

    Gas stations will be very rare, and parking spaces will almost always have charging stations.

    Having a garage in homes will be rare because car ownership will be rare. Using self-driving Uber-esque systems will be way more affordable, and car ownership then will be similar to antique car ownership now.

    Lawns will be very rare, and permaculture-style of local fauna that doesn’t need care, upkeep, or watering will be common.

    What do you think the future will look like?

    UAP are real and artifacts from non human intelligence. I just attended an event wt the capital factory in austin with some really respected people and now I’m wanting to come out: I’m convinced that UAP (unidentified aerial phenomena, the less stigmatized word for UFO):

    • are real
    • are craft from Non Human Intelligences (aliens)
    • USA gov and aerospace companies have actual materials from these craft and someone has an actual craft
    • have been hidden for security reasons for decades
    • we need to de-classify so we can put the weight of the usa innovation, research and capital markets to learn about this stuff and create technologies that benefit the wellbeing of humanity
    • we can learn to engineer einsteins relativity the way we learned to engineer Maxwell’s equations to do the crazy stuff people are seeing and seem
      Impossible
