If You Write or Read Science Fiction, Watch Isaac Arthur

So, I’m busy churning out some horror stories (most recent one involves some very disturbing elder abuse) and it has me in a bit of a dark mood. The sort of mood where you’re expecting to walk in the front door and find out someone has died. When I’m in the middle of these kinds of moods and really feeling the creepy energy of writing a truly horrible horror story I have to reach out to everyone I care about to make sure they’re still alive. And I show up at the house with flowers for the fiancee, just to try to shine some light back into my life.

And you know what helps with that feeling? What really helps keep it contained? Sensible cosmic wonder.

Sensible, rigorous well-thought out Cosmic Wonder.

May I introduce you to the charming and helpful Isaac Arthur (no idea if that’s a real name)?

He talks about everything, literally (not literally) and he does so IN DEPTH!

Really uplifting and educating.

  1. A new patent I just read about, will allow space elevators to be built with current materials.
    It has multiple tethers at its center ( for greatest strength ) and fewer tethers
    as you move away from center  ( for lesser amounts of mass ).
    Liftport has plans to build a Lunar elevator from current material.
    Using that same material for an Earth based elevator would reach the lunar gravity center
    (about 9,000 km AGL) approx. 1/6 G. Add this new concept and you could reach Earth’s surface.
    We can do this now. Let’s get started. What do you think?

    1. I’m all for anything that gets us into space. Also, if this is spam, may I just say that this is the best spam that has ever been written?

    2. No spam, also it is a modular system so the parts can be brought up and assembled in situ.
      Parts can be repaired, replaced or upgraded as necessary. And having multiple tethers throughout most of the system, if an asteroid comes by and takes out one or two tethers, you replace the damaged tethers and you are back in business.

      1. Do you have a link to this? I might incorporate it into some sci-fi stuff I’m working on. It’s called “The Age of Fusion” if you haven’t encountered it on the site yet.

          1. Looking at it now. very fascinating. Do you know how you would anchor the earthbound end? Seems like there could be quite a problem with positioning something like that.

  2. 1) There is no limit to the number of tethers you could have at the center of the system.
    The greater the number = the greater the break length, i.e. the length at which the system
    can no longer support it’s own weight for a given gravity well.
    2) You have fewer and fewer tethers as you move out from center both up and down
    until you taper down to a single tether at top and bottom. At the extremities the anchoring
    would be the same as the proposed plan for single strand space elevator concepts.
    I.S.E.C. (International Space Elevator Consortium) has lots of great info on that.

      1. My hope is, many more people will become as interested as you.It has been suggested – 100 years after the completion of the first space elevator there will be more people living and working in outer space than on earth. The first space elevator is difficult to build.The second is much easier.The third, easier still etc.,until we have a ring of elevators around the planet. A trip to space will be as cheap as a train trip across the country. Colonizing the Moon and Mars will be affordable. Space tourism will be huge.Asteroid mining will be huge.And all of these industries will require lodging and related supply chain infrastructure for space side construction workers.

        1. It’s been my hope that the ITS (the big SpaceX Rocket) will accomplish the same thing but of course that’s a bunch narrower pipe than a Space Elevator. I’ll have to slot this in around the 2070’s for the timeline of the stories I’m working on so it doesn’t mess up everything, but I’m very glad to hear this isn’t as far away as I thought. Would you mind if I emailed you a few questions when I get to that part of the story? I’m going to be pretty busy with Horror stories I’m finishing up for October but after that I intend to pump a lot of time into the Age of Fusion stories.

          1. The ITS will be the competition to a space elevator
            but it will always be like riding on a controlled bomb
            and it will always be confined by the size of the
            nose cone fairing. It will also be needed to bring
            the parts up for the first space elevator.
