Gravity matched Newton far beyond where surprises happen
A huge survey of nearly 686,000 galaxies spanning about 7 billion light-years tested gravity at unprecedented scale. Using cosmic microwave background data and the kinematic Sunyaev Zel’dovich effect, researchers measured galaxy motions with high precision. Gravity behaved exactly as Newton predicted, strengthening dark matter evidence and challenging ideas that gravity changes in deep space, while also backing parts of Einstein’s relativity.
- Nearly 686,000 galaxies were analyzed over 7 billion light-years
- Gravity’s behavior matched Newton’s prediction at cosmic scale
- Results bolster dark matter evidence over modified-gravity ideas
- Findings also align with parts of Einstein’s general relativity
