Scientists edge closer to detecting invisible dark matter that shapes galaxies

6d ago· 4 min readenNews

Summary

This article explores the mystery of dark matter and dark energy — invisible substances that scientists believe make up most of the universe. Dark matter does not emit, absorb, or reflect light, making it nearly impossible to observe directly, yet its gravitational effects on galaxies and galaxy clusters provide strong evidence for its existence. Dark energy is a separate concept describing the force driving the universe's expansion. The article discusses how researchers are approaching the detection of these elusive phenomena, potentially answering one of astronomy's hardest questions about what most of the matter in the universe is made of.

Dark matter is a name for something that does not emit, absorb, or reflect light, which makes it nearly impossible to observe directly.
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 energy is different. It is the term scientists use for whatever is driving the universe
