    The Twenty-Fifth Century

    This story takes its basic kernal of an idea from the old 1970s TV show Buck Rogers in the 25th century, but without the specific characters in that show, though there may be characters like them. One idea I'm adopting is that of stargates, a number of star systems are connected by star gates. The stargates are have spherical openings 100 km wide and are located 327 AU outside of each star system. There can be up to a total of six stargates around each star system arranged in a rosette formation arround each star. Wormholes are arranged so that they are one way to prevent collisions inside the wormholes. In systems where there are multiple stars, the wormholes need to be located either 327 AU from the system's center of mass or 3 times the maximum distance of the furthest stellar companion, which ever is greater.

    Here is a list of the star systems in the network, this list isn't exhaustive. There are basically four clusters centered on the Sol system, the first connects Sol to Alpha Centauri and Barnard's Star, these three star systems are the members of the Sol cluster and each star of that network connects to one star system that the other two members do not. The Sol system for example has two wormholes 1 and 2 leading to Alpha Centauri, two wormholes 3 and 4 leading to Sirius, and two wormholes 5 and 6 leading two Barnard's star, but the Sirius system can only be reached from Sol in this cluster, the other two star systems do not have wormholes leading to Sirius.

    Here are the Star Systems connected by the wormholes with their basic information, which I've obtained from Each star system component has its own line with each property listed in the following order: Star type, Mass in Solar Masses labled (S), Diam for Diameter in Solar Diameters (S), Lum for Luminosity on Solar Luminosities (S). Between each component line is the minimum and maximum seperation of the two components in Astronomical Units (AU). I haven't had time to do them all.

    This second part is a classification system for different planet types that I have found useful which I haven't included in the first part because apparently it was too large, but here are the basic categories:

    First we have the standard solid planets, these are planets with surfaces that you can walk on: I've listed them in a single character alpha-numeric, the first number is the body's average mass in Earth Masses (E), the second number is the body's size in Earth diameters or radii (E) if you prefer, and the third number is the body's average diameter in kilometers (km). If I want to determine a terrestrial planet randomly I roll three six sided dice and sum the results. An example of a type of planet from our solar system is sometimes provided to the right of the columns.

    3d6 Terrestrial Planet Sizes
    X = Mass Size(E) -- km
    0 = 0.000 0.000 -- 00,000
    1 = 0.005 0.170 -- 02,168 Pluto
    2 = 0.020 0.271 -- 03,456
    3 = 0.045 0.355 -- 04,528 Mercury
    4 = 0.081 0.432 -- 05,510
    5 = 0.127 0.502 -- 06,403 Mars
    6 = 0.183 0.567 -- 07,232
    7 = 0.250 0.629 -- 08,023
    8 = 0.326 0.688 -- 08,776
    9 = 0.413 0.744 -- 09,490
    A = 0.510 0.798 -- 10,179
    B = 0.617 0.851 -- 10,855
    C = 0.734 0.902 -- 11,505
    D = 0.862 0.951 -- 12,130 Venus
    E = 1.000 1.000 -- 12,756 Earth
    F = 1.147 1.046 -- 13,342
    G = 1.306 1.093 -- 13,942
    H = 1.474 1.138 -- 14,516
    I = 1.653 1.182 -- 15,077

    I have an interesting idea about who built the wormhole network. A group of humans evolved on a planet orbiting a G2 V star in a satellite galaxy 63,500 light years away. The Saggitarius Dwarf Galaxy. Humans from this distant galaxy observed an abundance of usuable Worlds in the immediate vicinity of the Solar System, so they crafted a number of worlds using Wormhole Tenders to deliver wormholes from their home system to the Solar neighborhood. We'll call the planet they lived on Draconia, it contains an ecosystem similar to Earth, it existed 2 billion years in the past. By looping wormholes 15,748 times from Sag-Deg to Earth are relativistic velocities, they could establish a local connection to the future while guiding the evolution of several planets so they'd be compatible with humans, though a secret faction of draconian society interfered with evolution on Earth, causing humans to evolve seperately on this planet in such a way as to appear a natural outgrowth of evolution.

    As you know wormholes can be used as time machines
