Quotes About Lensing

Black holes do not emit light, so you visualize them through gravitational lensing - how they bend light from other objects.

We cannot explain the phenomenon of gravitational lensing without general relativity, and this is where MOND spectacularly fails.

Recent results from astronomers who study the occasional gravitational lensing of unknown worlds by intervening stars suggest that orphan planets could be at least as numerous as the stars. In other words, there could be hundreds of billions of orphan worlds shuffling through our galaxy.

The precise effects of lensing depend on the mass of the lens, the structure of space-time, and the relative distance between us, the lens, and the distant object behind it. It's like a magnifying glass, where the image you get depends on the shape of the lens and how far you hold it from the object you're looking at.
