What happens if we take off from Earth, leave the Solar System and our Galaxy with its billions of stars? Even on such large scales, astronomers are now able to describe the Universe. Around vast completely empty areas, galaxies are made up of long filaments that connect to one another by some kind of knots... And that's not the full stio, as astronomers are also able to detect the "lumps" in the past of the cosmos that gave birth to these large structures thirteen billion years ago.
