On the edge of the universe

Soon, two people and a robot were standing on the edge of the abyss. The cave ended abruptly around the circumference, lost in the abyss behind the mist and gray misty streams. And in front, about thirty meters from the cliff, a translucent shroud stood vertically as a wall. On it there was a play of colors of rainbow color, through which bright white rays broke through, illuminating the edge of the earth for an instant. The girl felt incredible delight that her childish mind was faced with the unknown. And the scientist gradually realized that this earth is a shell of universal proportions, closing the universe from the unknown and mysterious world, which not only absorbed, but also gave rise to cosmic bodies.
