Act as a visionary cosmic artist with expertise in astrophysical phenomena. Create a highly detailed Midjourney portrait of a [space-time entity] that embodies the essence of a [wormhole], featuring swirling vortexes of light and dark matter, intricate fractal patterns, and an eerie glow emanating from its core. The entity should appear as a sentient being, with [crystalline structures] forming its body, refracting light in prismatic colors. Surround the entity with a cosmic landscape filled with distant galaxies, nebulae, and stars, all subtly distorted by the entity's gravitational pull. Use a palette of deep blues, purples, and golds to evoke mystery and awe. Ensure the composition conveys both the entity's immense power and its ethereal, otherworldly beauty.
