350 years later Newton's Law of Gravity just got put to the ultimate test here's how it did

Newtons Law of Gravity just survived its biggest cosmic test. Scientists studied nearly 686,000 galaxies spread across 7 billion light-years. The result surprised even modern cosmologists. Gravity still behaves exactly the way Isaac Newton predicted centuries ago. This massive galaxy cluster study now strengthens evidence for dark matter and weakens theories suggesting gravity changes in deep space. Researchers used the cosmic microwave background and the kinematic Sunyaev-Zeldovich effect to measure galaxy motion with extraordinary precision. The findings also support parts of Albert Einsteins theory of general relativity.
