Web12 Jan 2010 · The dark matter of gravitational lensing. Richard Massey, Thomas Kitching, Johan Richard. We review progress in understanding dark matter by astrophysics, and particularly via the effect of gravitational lensing. Evidence from many different directions now all imply that five sixths of the material content of the universe is in this mysterious ... WebExplanation: Albert Einstein's general theory of relativity, published over 100 years ago, predicted the phenomenon of gravitational lensing. And that's what gives these distant galaxies such a whimsical appearance, seen through the looking glass of X-ray and optical image data from the Chandra and Hubble space telescopes.

It explained that the smile was an effect that is known as gravitational lensing, which is a distribution of matter between a source and the observer during its travel towards the observer. WebThe geometry of a lens system is shown in Figure 12.2. A source located at point S is emitting light that is deflected by a lens located between the source and some observer, located at point O. The lens could be anything with mass: a star or planet, or a galaxy or cluster of galaxies. m7 laboratory\u0027s
