dark matter
Sign in to savemysterious non-luminous matter (and/or radiation) comprising most of the matter in our observable universe
AI overview
Dark matter is invisible material that doesn't emit light but makes up most of the matter in our universe, detected only through its gravitational effects on visible objects like stars and galaxies. Scientists study it because understanding dark matter is essential to explaining how galaxies form and move, and how the universe itself is structured.
