Instead of inflation smoothing the universe, slow contraction before the bounce did it. No multiverse, no singularity, maybe no beginning at all. 🌌

#Cosmology

Elegant but largely ignored—the road not taken in string theory.

#StringTheory

It doesn't exist in nature (our universe has positive curvature), but AdS/CFT made it the cornerstone of quantum gravity research. Sometimes the best lab is one nature didn't build. 🔬

#TheoreticalPhysics

It's not just mathematical—our universe is evolving toward de Sitter space as dark energy dominates. In the far future, we'll live in empty, exponentially expanding space. 🌌

Wondering how many people use email not provided by google/microsoft such as proton.

A 0-dimensional brane is a point-like object, a "pinpoint" in spacetime where strings can end.

They're like fundamental particles that help us model everything from M-theory to the quantum secrets of black holes.

❤️ General Relativity (rules the big cosmos 🌌)
❤️ Quantum Mechanics (rules the tiny particles ⚛️)

Their baby would be called Quantum Gravity, the ultimate Theory of Everything that could finally explain black holes!

MOND successfully predicts galaxy rotation curves, the Baryonic Tully-Fisher relation, and other galactic phenomena without fine-tuning.

However, it faces challenges with galaxy clusters, cosmology (like the CMB), and Solar System tests, where it still requires some form of missing mass or refinement. Relativistic versions are in development to address these issues. #MOND #DarkMatter #Astrophysics #cosmology
