Albert Einstein theorized the concept in 1915, and the term &#8216;black hole&#8217; was coined in the mid-1960s by American physicist John Archibald Wheeler.<\/p>\n\n\n\n<div style=\"height:19px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p class=\"wp-block-verse\" style=\"font-size: 18px; text-align: justify;\"><strong>A galaxy is a massive collection of gas, dust, and billions of stars and their solar systems, all held together by gravity.

But some black holes are truly massive and are billions of times the mass of our Sun and inhabit the center of most galaxies. How these are found at galaxy centers is unknown. But it&#8217;s clear they energize the galaxy and will influence its evolution. By studying black holes, scientists can learn about the evolution of galaxies and perhaps even about the beginning of the universe.<\/p>\n\n\n\n<p class=\"wp-block-verse\" style=\"font-size: 18px; text-align: justify;\">This recent discovery was accomplished by the Event Horizon Telescope, a combination of eight widely spaced radio antennas to mimic a telescope the size of our planet.
