FAQ About Vera Rubin
What is dark matter, the concept Vera Rubin helped to illuminate?
Dark matter is a form of matter that does not interact with electromagnetic forces, meaning it does not absorb, reflect, or emit light, making it invisible and detectable only through its gravitational effects on visible matter, radiation, and the large-scale structure of the universe. Rubin's work provided some of the first compelling evidence for its existence by observing how galaxies rotate.
