In the unseen realms beyond the glow of stars, whispers travel through the ethereal threads of dark matter. Here, lurk the Ethereals, beings woven from pure energy, their forms shimmering like constellations against the cosmic canvas. They dance among the invisible scaffolding of the universe, influencing the flow of gravity with their thoughts and dreams. Though unseen by mortal eyes, the Ethereals are the silent architects, shaping the very fabric of existence from the shadows. - The NASA "Dark Matter Universe" poster isn't tied to a specific story, but rather to the vast, mysterious reality of dark matter. This invisible substance makes up 85% of the matter in the universe, but we can't directly see it. The poster uses the concept of dark matter to spark our imaginations about what might exist beyond the veil of the known universe. It hints at unseen forces, hidden structures, and the potential for civilizations unlike anything we can conceive. - This file is in the public domain in the United States because it was solely created by NASA.
