Health and Inequality: Impact on Well-Being Explored
How does gravity actually work? Explore Newton's law of gravitation, Einstein's general relativity, gravitational waves.
The exact change
Title read "Health and Inequality: Impact on Well-Being Explored" but the article body was entirely a practical spaced-repetition guide: "...the Leitner box system sorts flashcards into review boxes by recall difficulty... effective cards follow the atomicity principle, one fact per card... cloze deletion format..." with no mention of gravity, Newton, or Einstein anywhere in the body.
Title now reads "How Gravity Works: From Newton to Einstein's Spacetime" and the body genuinely covers gravity: "...Newton's 1687 law of universal gravitation correctly predicted Neptune's existence in 1846... Mercury's perihelion precession was the crack in Newton's picture that Einstein's 1915 general relativity resolved by describing gravity as spacetime curvature... LIGO's September 14, 2015 detection of GW150914 confirmed gravitational waves directly for the first time..."
Suggested change
Replaced the title, meta_title, and entire article body with original, verified content on how gravity works: Newton's 1687 law of universal gravitation and the 1846 Neptune prediction, Mercury's perihelion precession, Einstein's 1915 general relativity, the 1919 Eddington eclipse test, gravitational waves (LIGO's September 2015 GW150914 detection and the 2017 GW170817 neutron-star merger), and the unsolved quantum gravity problem. Slug, excerpt, meta_description, tags, and FAQ were left unchanged as they were already correct.
Why this is better
A content-management bug resulted in an unrelated spaced-repetition/flashcard-implementation article (a distinct article from the one misplaced into post 1065, same topic family) being published under this page's title and URL, even though the slug, excerpt, meta_description, tags, and FAQ were already genuinely and correctly about gravity. The wrong title and body were replaced with original, verified gravity content. This supersedes the SUPERSEDED note left on contribution 562 (a minor citation fix that lived inside the old misplaced spaced-repetition text and no longer appears on the page); this new contribution documents the full content-swap correction itself. Verified live: the page title and body now match its slug and topic.
