Cosmic Shear: Revealing the Invisible Universe

The video explores dark matter, an invisible substance crucial to the universe's structure. It discusses cosmic shear, a subtle effect of gravitational lensing, used to detect dark matter. By analyzing galaxy distortions, scientists map dark matter's distribution, revealing the universe's web-like structure. This mapping helps understand the universe's evolution and the interplay between dark matter and dark energy, which shapes cosmic structures over time.
