Did Gravity Ever Change? Science Finally Answers

The Brief

  • The video asks whether the gravitational constant has stayed constant or changed over time.
  • Chapters indicate sections on red dwarfs as evidence about the constant, gravitational waves, why the idea was proposed, the Moon, chemistry, and galactic structures.
  • The description cites three papers (arXiv 2610.04048, arXiv 2003.12832 and a Physical Review D article) as sources.

Why watch · It examines whether one of physics' fundamental constants might vary, a question with implications for gravity tests and cosmology.

  • Gravitational constant
  • Red dwarfs
  • Gravitational waves
