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.

What is the significance of mapping dark matter in the universe?

Discuss the relationship between dark matter and dark energy as described in the text.
