Left right split scene of future and now

Create a surreal split-scene where the left half shows [a man standing on a modern city street, facing to the right, and touching the wall with his finger], and the right half depicts [the same man on a futuristic space street, facing to the left, and touching the wall with his finger]. The two halves are separated by a vertical wall held by a magical force, as if the ocean has been cut in half. The scene should align across both sides, maintaining realism while showcasing this impossible scenario.
