One night, I had a dream. In the boundless vastness of the universe, a single massive planet kept expanding endlessly. Its sheer scale surpassed the limits of what my human mind could comprehend. For the first time, I felt the fear of infinity — an existential terror born from confronting the incomprehensible. It was the first time I truly pondered the concept of infinity itself. Even after all these years, I can’t forget that nightmare. This simulation is my attempt to recreate it.
