Why It's IMPOSSIBLE to Escape Our Local Group of Galaxies | Brian Greene

In this deep-dive, theoretical physicist Brian Greene explains why it’s physically impossible to escape our Local Group of galaxies. We explore the cosmic forces that bind galaxies together, the role of gravity and dark matter, and how the accelerating expansion of the universe places hard limits on travel beyond our cosmic neighborhood. You’ll learn what the Local Group is, why distant galaxies are effectively receding beyond reach, and how cosmic horizons limit what any civilization—no matter how advanced—could ever access. This video separates sci-fi fantasy from real physics and shows why our future in the cosmos is constrained by the structure and expansion of spacetime itself. ⚠️ Disclaimer This content is for educational and informational purposes only.
