Stephen Hawking

Create a portrait of Stephen Hawking, the renowned theoretical physicist, seated in his iconic wheelchair, which is intricately detailed with high-tech features. His expression is one of deep contemplation, with piercing blue eyes that reflect a lifetime of curiosity and intellect. Surround him with a cosmic backdrop filled with swirling galaxies and stars, symbolizing his groundbreaking work in astrophysics. The lighting should be soft yet dramatic, casting gentle shadows that highlight his facial features and the contours of his wheelchair. Incorporate elements like equations and black holes subtly integrated into the background, blending science with art. The overall mood should evoke a sense of wonder and inspiration, capturing Hawking's legacy as a brilliant mind who transcended physical limitations. Use a realistic style, emphasizing textures in his clothing and the sleekness of his technology, to create a powerful and moving tribute to his life and contributions to science.
