• #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.
