Our existence is limitless. We don't know time, as it's not part of us. But we know the Universe, as we are born in it. The Universe is our Father. Mother. Brother. Sister.
A medium-sized, perfectly-shaped black cube drifts in space. No one could really tell for how long, but if it could talk, it could tell someone wonderful stories of the stars and nebulas it seen, traveled through. After an uncountable years of it's journey, cube finally reaches new spaces. Spaces someone in future will call "Sirius". But for now, it'll silently wait and spectate it's surroundings. It's time to finally fulfill it's function, destiny, as some may say, will come. But not now, not soon. It'll happen only when a space-young race will put their first spaces into Sirius. It'll happen after hundreds of years of waiting. Then, cube will open, reveal something it kept safely inside for centuries and in this way it'll fulfill it's destiny.
