Astrophysics

Early universe

A compact glowing sphere representing the very early universe as an extremely hot, dense, nearly uniform primordial fireball. It has a bright white-yellow core that fades smoothly into orange and red toward the edges, with a smooth circular outline, subtle mottled plasma-like texture, and a luminous radiant appearance. Tiny scattered points of light may be present within the glowing field to suggest a young uniform cosmos before mature structures formed. No surrounding scene or background stars. Flat vector-style rendering with smooth gradients, clean edges, and minimal detail.
