The revolutionary theory remains foundational to our models of how the Universe formed and evolved. One of the many things GR predicted was what is known as gravitational lenses, where objects with massive gravitational fields will distort and magnify light coming from more distant objects. Astronomers have used lenses to conduct deep-field observations and see farther into space.<\/p>\n<p>In recent years, scientists like <a href=\"http:\/\/www.maccone.com\/\">Claudio Maccone<\/a> and <a href=\"https:\/\/science.jpl.nasa.gov\/people\/turyshev\/\">Slava Turyshev<\/a> have explored how using our Sun as a Solar Gravity Lens (SGL) could have tremendous applications for astronomy and the Search for Extratterstiral Intelligence (SETI). Two notable examples include <a href=\"https:\/\/www.universetoday.com\/155642\/using-the-sun-as-a-gravitational-lens-would-let-us-see-exoplanets-with-incredible-resolution\/\">studying exoplanets in extreme detail<\/a> or creating an <a href=\"https:\/\/www.universetoday.com\/150671\/gravitational-lenses-could-allow-a-galaxy-wide-internet\/\">interstellar communication network<\/a> (a \u201cgalactic internet\u201d). In a recent paper, Turyshev proposes how advanced civilizations could use SGLs to transmit power from star to star \u2013 a possibility that could have significant implications in our search for technosignatures.<\/p>\n<p>The preprint of Turyshev\u2019s paper, \u201c<a href=\"https:\/\/arxiv.org\/pdf\/2310.17578.pdf\">Gravitational lensing for interstellar power transmission<\/a>,\u201d recently appeared online and is being reviewed for publication. <a href=\"https:\/\/science.jpl.nasa.gov\/people\/turyshev\/\">Slava G.
