Scientists edge closer to detecting invisible dark matter that shapes galaxies
Summary
This article explores the mystery of dark matter and dark energy — the invisible substances that make up most of the universe. Scientists can infer their existence through gravitational effects on galaxies and galaxy clusters, but cannot observe them directly because they don't interact with light. The piece discusses how close researchers are to finally detecting dark matter and answering one of astronomy's biggest questions.

· 3 pulled'Dark' in dark matter and dark energy does not mean evil or dangerous. It means unknown.
Based on how galaxies rotate and how galaxy clusters hold together, researchers infer that there is more mass present than we can account for using visible matter alone.
Dark matter is a name for something that does not emit, absorb, or reflect light, which makes it nearly impossible to observe directly.
