The Strange Universe of Gravitational Lensing

The video explores gravitational lensing, a phenomenon where light is bent by gravity, causing shifts and magnifications in the universe. It discusses Einstein's theory of relativity, Eddington's 1919 experiment, and the applications of lensing in studying galaxies and dark matter. The video also covers the measurement of cosmic distances, the analysis of quasars, and the role of weak lensing in mapping the cosmic web. Additionally, it delves into the extreme lensing around black holes and the concept of quantum tunneling, touching on various interpretations of quantum mechanics.

What is the warping effect of gravitational lensing and how does it affect our perception of the universe?

How does our brain's internal model of space differ from the actual structure of the universe?

Explain the significance of Einstein's general theory of relativity in understanding gravitational lensing.

Describe the experiment conducted by Sir Arthur Eddington in 1919 and its implications for general relativity.

What is strong lensing and how does it differ from weak lensing in the context of gravitational lensing?
