*Can astronomical observation ever answer the question of whether the universe is infinite or finite?*
Priya Natarajan explains that while observations reveal a finite observable universe, they do not yet tell us whether space beyond the cosmic horizon is ultimately finite or infinite. She discusses curvature, inflation, singularities, and the limits of current cosmology.
0:00 Infinite or Finite Universe?
1:37 The Finite Observable Universe
2:41 Beyond the Cosmic Horizon
4:07 What Current Observations Suggest
6:17 Black Hole and Big Bang Singularities
8:35 Why Quantum Gravity Matters
*Priyamvada "Priya" Natarajan* is a theoretical astrophysicist and professor of astronomy and physics at Yale University. Her work on mapping dark matter and dark energy through gravitational lensing has made her one of the leading figures in modern cosmology.
