In this very sphere, every one of the 380.000 lasered dots is not only a star, but an entire galaxy with billions of stars. A journey through our entire galaxy, the Milkey Way, would last 120.000 years...with the speed of light! and it contains of 300 billion stars. A journey to our nearest neighbor, the Andromeda galaxy, would last around 2.5 million years with that speed. And there we are, at the first tiny dot, next to our own tiny dot in the center of this very sphere. If you add the next 100 000 Galaxies you can see the structure of Laniakea, our home supercluster. Laniakea is around 160 megaparsec in size and of cause surrounded by even larger structures.
- The diameter of the cloud of galaxies in the sphere is around 250 megaparsec (Mpc). One Parsec is equal to 3.2616 lightyears, which means, that the cloud is 815.400.000 lightyears in diameter. 815 million years of travel, with the speed of light, captured in an 8cm glass sphere.
- With all these information, this sphere convinced me, that we can´t be alone in the universe.
