    The Voyager update project
    Description has not yet been created.
    Now playing SpaceCollective
    Where forward thinking terrestrials share ideas and information about the state of the species, their planet and the universe, living the lives of science fiction. Introduction
    Featuring Powers of Ten by Charles and Ray Eames, based on an idea by Kees Boeke.
    I do not believe that any one person would be able to finance this project, no matter how ambitious or wealthy they are. The size of this project, the massive time frame that is need to complete it and to see results and the political complexities of marking that planet can not be supported by a single philanthropist or corporation.

    As I see the issues of funding and supporting the Lighthouse Project, money is the least of our concerns. Sure it will be expensive, but the cost will not be much more than a normal space launch. The real costs also will not be a one time purchase of materials and equipment, but will be a long term commitment to funding research, development and maintenance.

    I believe that a space oriented international lobbying group would be our best bet to get the money we need and also the long term support. Currently there are several such groups that lobby for various outer space treaties.

    The Outer Space Treaty of 1967 (Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies) is a past example of a successfully lobbied treaty.

    The treaty forbids anyone from making claim to a planet or the moon and claims them as "common heritage of humanity."

    According to Wikipedia, 98 countries are states-parties to the treaty, while another 27 have signed the treaty but have not yet completed ratification.

    At state party is a group of representatives from each country that has ratified the treaty, and could be a good model for supporting our project.

    More recently there has been a propose Space Preservation Treaty. Its most viable goal is to stop space weapons but its goal is international space cooperation.

    The Institute for Cooperation in Space is one group that has put forward most of the support for this treaty. They have gotten it in front of the House of Representatives 4 times now and have funding for future efforts from 274 non-profit organizations.

    They were founded in 2001 but follow up the work of several long standing organizations. They have the money, connections and determination to support our project now and to garner it funding in the future.

    Cosmic Background Radiation is essentially a left over from the cooling of the universe. It originated 400,000 years after the big bang. This was the time of last scattering, which is when the universe had cooled enough that there wasn't enough energy to keep electrons and protons apart. So the universe went from being a plasma to consisting of helium and hydrogen and the areas the were more dense with these kept attracting more and more matter around them and formed the galaxies.

    Our instrument of detecting CBR:

    Horn Antenna:

    COBE (Cosmic Background Explorer) 1989

    Cosmic Background Imager (in the Andes)
    {image 30}
    WMAP (Wilkinson Microwave Anisotropy Probe ) 2001

    The WMAP has recently mapped a large portion of the sky and found that there are ripples in the CBR. These ripples have been turned into sound clips.

    Ways to use CBR as a beacon:

    The CMB photons scatter off free charges such as electrons that are not bound in atoms. In an ionized universe, such electrons have been liberated from neutral atoms by ionizing (ultraviolet) radiation. Today these free charges are at sufficiently low density in most of the volume of the Universe that they do not measurably affect the CMB. However, if the IGM was ionized at very early times when the universe was still denser, then there are two main effects on the CMB:

    1. Small scale anisotropies are erased (just as when looking at an object through fog, details of the object appear fuzzy).
    2. The physics of how photons scatter off free electrons (Thomson scattering) induces polarization anisotropies on large angular scales. This large angle polarization is correlated with the large angle temperature perturbation.

    So if we can ionize (removing charged particles such as electrons) parts of the CBR around us it will change the ripples (small scale anisotropies) in the areas around our galaxies

    There have already been machines built that have been able to do massive scale ionization on earth. This was done in the hopes of being able to control the weather and is called atmospheric ionization.

    We could attempt to do the same with a satellite the orbited each planet or the entire solar system. The scale of such a project would be immense, but completing such a project quickly does not seem like a priority. Not to mention as soon as it started we would be marking ourselves, even if it is unlikely that with only a small bit marked anything would notice.

    While researching Cosmic Background Radiation, I can across a few sound clips.

    They are a conversion of ripples in the radiation that have been converted to the frequencies that we can hear.

    They show ripples in the CMB which are subtle variations in the density of matter which can, in one sense, be thought of as sound waves.

    These cosmic sound waves are 30,000 light-years wide and are 55 octaves below what humans can hear.
