Learn about Dark Matter — Simply Explained
Dark matter is an invisible substance that makes up about 27% of the universe. We can’t see it or detect it directly, but we know it exists because of its gravitational effects — galaxies rotate faster than they should based on visible matter alone, and light bends around seemingly empty regions of space.

If we can't see dark matter, how do we know it's real?+
We observe its gravitational effects: galaxies spin too fast, galaxy clusters bend light more than expected, and the large-scale structure of the universe only makes sense with dark matter included in our models.
What is dark matter made of?+
We don’t know yet! Leading candidates include WIMPs (Weakly Interacting Massive Particles) and axions, but none have been directly detected. It’s one of the biggest mysteries in physics.
Is dark matter the same as dark energy?+
No. Dark matter is an invisible substance with gravitational pull that holds galaxies together. Dark energy is a mysterious force that’s pushing the universe apart and accelerating its expansion.
