Dark Matter: Scientists Agree on Its Existence, Debate Continues

Rapid Summary

• Fact of Existence: Dark matter, a mysterious and invisible substance that does not interact with light or electromagnetic radiation, is thought to make up approximately 27% of teh universe’s matter and 85% of total mass. Its existence is largely accepted by scientists based on indirect evidence, though some skeptics question its reality.
• Scientific Understanding: first described in the 1930s, scientists still have limited knowledge about dark matter’s composition and properties. Proposed theories include it being composed of “weakly interacting massive particles” (WIMPs).
• Detection Efforts: Direct observation remains elusive despite strong hints from phenomena like gravitational lensing. Underground sensors are being developed globally to detect its interactions with subatomic particles-Sanford Underground Research Facility houses one such large detector.
• Risks to Humans: While extremely unlikely for humans to come into contact with dark matter due to its weak interaction with normal matter, hypothetical scenarios involving large dark matter particles or microscopic black holes could be fatal but have no evidence supporting their occurrence.
