• Our #scientific understanding of #gravity was established by #IsaacNewton in 📆 1687.

• In 📆 1915, #Einstein published "The General Theory of #Relativity."

#DarkMatter was first theorized in the 📆 1930s to explain movements of #stars 🎇 and #galaxies 🌌 that couldn't be explained by Newton's laws of gravity.

• Modified Newtonian dynamics (#MOND) was first proposed by Mordehai Milgrom in 📆 1983. https://www.youtube.com/watch?v=Qkl2ASn9yyA

• Recently, a new study has found direct evidence for a modified theory of gravity based on #Gaia telescope 🔭 observations.

The mystery of what actually is remains the ultimate challenge of modern fundamental physics. The core question is whether it is indeed a missing mass source, such as a new type of matter, or whether the law is simply different at gigantic length scales. While laws are well tested within the , one has to be careful extrapolating this to scales which are at least one billion times larger. https://phys.org/news/2019-01-dark-alternative-theory.html
