dark-matter

Dark matter is the invisible backbone of the universe — you can’t see it, touch it, or detect it directly, but its gravity holds galaxies together and shapes the cosmic web.

Scientists estimate it makes up about 85% of all matter, yet it doesn’t emit light or energy like normal matter. We only know it’s there because galaxies spin too fast and light bends around massive clusters in ways visible matter alone can’t explain.

Think of it like a hidden framework: the stars, planets, and everything we see are just the surface — dark matter is the structure underneath.

Bottom line:
Dark matter is unseen, but without it, the universe as we know it wouldn’t exist.
