A black hole is a region of space where matter has become so densely packed that its gravity will let nothing escape \u2013 including light.<\/p>\n

Time comes to a stop at its edge, and its centre may hide a point of infinitely small volume and infinite density, where all laws of physics break down.<\/p>\n

Possessing the terrifying power to devour anything unlucky enough to pass within their grasp, it is little surprise that these cosmic chasms have become a staple of sci-fi since the term \u2018black hole<\/a>\u2019 was coined in 1964.<\/p>\n

Read our answers to some of the big questions about black holes<\/a>.<\/strong><\/em><\/p>\n

Despite their abundance, there is no reason to panic: black holes will not devour Earth nor the Universe. It is incredibly unlikely that Earth would ever fall into a black hole.<\/p>\n

This is because, at a distance, their gravitational pull is no more compelling than a star of the same mass.<\/p>\n

If we were to replace the Sun with a black hole of the same mass, for example, Earth and the rest of the planets would continue orbiting in exactly the same way, because there would be no discernible change in the gravity acting on them.<\/p>\n

If our Sun were replaced by a black hole, however, it would get very dark and cold in our Solar System.<\/p>\n

The only way Earth could be swallowed by a black hole would be if our planet happened to stray across a wandering black hole\u2019s event horizon.<\/p>\n

That\u2019s something that is not going to happen any time soon, and likely never will.<\/p><\/body><\/html>\n
