What can we learn from gravitational lensing?

<p>What information is obtainable through gravitational lensing and how? Patrick A. CloughWichita, Kansas Gravitational lensing is the effect by which comparatively nearby objects, such as clusters of galaxies, can bend and focus the light of other objects that are more distant. Lensing is only possible because highly massive, and therefore gravitationally powerful, objects distort the space-time continuum around them. <a class="more-link" href="https://www.astronomy.com/science/what-can-we-learn-from-gravitational-lensing/">Continue reading <span class="screen-reader-text">"What can we learn from gravitational lensing?"</span></a></p> <p>The post <a href="https://www.astronomy.com/science/what-can-we-learn-from-gravitational-lensing/">What can we learn from gravitational lensing?</a> appeared first on <a href="https://www.astronomy.com">Astronomy Magazine</a>.</p>
