Hubble Science: Gravitational Lensing, Nature’s Boost

The video discusses galaxy clusters held together by gravity, which distort space-time as predicted by Einstein. Using the Hubble Space Telescope, scientists observe gravitational lensing, where light from distant galaxies is bent, allowing for detailed observation. This lensing effect also helps map dark matter distribution in galaxy clusters, revealing that most mass in these clusters is dark matter, not visible stars.

What is the relationship between mass and the distortion of space according to Einstein's predictions?

Discuss the implications of being able to map dark matter through gravitational lensing.
