The Zero Universe
proportions2 
Proportions: When figures about dimensions of atoms or stars and planets are written down or displayed otherwise, it are numbers that are very big or very small, but most of the time they say not more than very big or very small.  Reducing this figures to a more humanitarian scale gives some insight about size and distances. The Universe: When the Sun is shrinked to 1 mm then Earth has a cross-cut of 9 micrometer or 0,009 mm at a distance of 11 cm. The cross-cut of Jupiter is the 100 micrometer or 0,1 mm at a distance of 56 cm. For the no longer acknowleged planet Pluto the cross-cut is 2 micrometer or 0,002 mm at a distance of 4,25 meter. The closest star is Proxima Centauri with a cross-cut of 0,145 mm at a distance of 29.225 m or 29 km. In a sphere of 29 km there is nothing, just some atoms and space garbage and sometimes an astoroid or comet. In a galaxy stars are on average 4,5 lightyears apart from each other, however in the centre of galaxies stars are about 1 lightyear apart from each other; in the forementioned examples this is about 6 km. When 2 galaxies cross each other, one emptiness goes through another emptiness and the number of colliding stars is very low. Galaxies like ours and for example Andromeda have a cross-cut of 200.000 lightyears at a distance of about 2,5 milion lightyears from each other. In the same ratio as before the distance is 17,3 billion km and the cross-cut 1,7 billion km. The distance Earth-Sun is 150 milion km; light with a speed of 300.000 km per second needs 8,5 minutes. Between galaxies is emptiness and only single atoms. The space between galaxies is about 10-100 times their cross- cuts. So overall the universe is very very empty.
