Each room has walls. These walls are part of the building that stands on Earth. The Earth “hovers” in space, making a circle around the solar system. The sun rushes through the Milky Way galaxy, drowning in the myriad of neighboring stars. And so, we came to the fact that the galaxy is just a grain of sand on the black canvas of the cosmos. A canvas that extends to infinity. There is no wall that makes room a room. There is no cycle that will return everything to the starting point after a certain time. There is no neighboring “other emptiness”. There is only limitless anywhere. It fascinates and scares at the same time. You can stand up for hours with your head and look at the canvas of stars, but for today’s man – it will always be just a beautiful picture that inspires lovers for centuries, does not let scientists sleep and drives mad folks who dare to comprehend the infinity of the universe.
