This data is a map of the sky at a specific microwave frequency "inverted" where the areas with higher "elevation" represent area in the sky where the CMBR has more intensity. This radiation was emit 370000 year after the Big Bang when the protons and electrons cooled enough to form hydrogen atoms. This epoch was called the Recombination Epoch, when the universe was a white fog. The radiation of the CMBR frequency is 160.23 GHz, corresponding a black body temperature of 2.72548 K.<br>It is not totally true to say this model has a scale, because it does not represent a geographic relief but a intensity of radiation. This 13 cm model represent a surface at a distance (say<i><strong>r</strong></i>) travelled by the light since the year 370000 after the Big Bang (13772 million year ago), so this surface is that of a sphere of radius <i>r</i>. The hydrogen atoms on this surface produced the CMBR that we see today. This sphere is the speed of light 299792458 m/s multiplied the<i> </i>time since the Big Bang in second, of radius; giving a diameter<i> of 2.6 </i>10^26 meters. Consider the model is about 13 cm in diameter that result on a scale of 1 in 2 10^28, which is, in short scale, 20 octillion, and in long scale, 20 thousand quatrillion.<br>The matter in the universe that emitted the CMBR is at the <strong>present</strong> farther away than is now, because of the expanding nature of the universe, 4.4 10^26 meters away, 3.3 times the distance <strong>then</strong>.<br>The original map was modified to enhance the low frequency variation areas. Also, the final model was simplified to make "visible" for the Thingiverse 3D viewer.</p><h4>References</h4><ul><li><a href="http://planck.cf.ac.uk/all-sky-images">http://planck.cf.ac.uk/all-sky-images</a></li><li><a href="https://www.mathworks.com/matlabcentral/fileexchange/4512-surf2stl">Surf to STL function for MATLAB&nbsp;</a></li></ul><h3>Other astronomical objects</h3><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49826">Inner Solar System</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49832">Artificial</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49820">Near Earth Asteroids</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49291">Main Belt Asteroids</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49829">Jovian System</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49828">Saturn System</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49830">Uranian System</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49345">Neptunian System</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49827">Centaurs</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49833">Comets</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49341">Trans Neptunian Objects</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49824">Extrasolar Objects</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49837">Sky Maps</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49831">Ancient</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49822">Speculative</a></p><p><a href="https://www.prusaprinters.org/social/120859-tato_713/collections/49821">Science Fiction</a></p>
