Create a cosmic scene featuring three humanoid figures standing closely together

Create a cosmic scene featuring three humanoid figures standing closely together, each holding a glowing, transparent cube emitting light. The central figure should be dressed in a formal suit and tie, while the two figures on either side wear futuristic attire. Their heads should appear as bright, cosmic voids, filled with stars and nebulas, with no distinct facial features. The overall color scheme should include vibrant blues, purples, and whites, creating a mystical and powerful atmosphere. The background should be a swirling cosmic environment with abstract elements like galaxies, nebulas, and light trails, enhancing the ethereal and futuristic mood. The image should be in a 16:9 aspect ratio, capturing the grandeur of the scene.
