Thank you for this great question. The short answer, unfortunately, is no.<\/p>\n<p>White holes are really just something scientists have imagined \u2014 they <em>could<\/em> exist, but we\u2019ve never seen one, or even seen clues that one may exist. For now, they are an idea.<\/p>\n<p>To put it simply, you can imagine a white hole as being a black hole in reverse. So if time was running backwards, black holes would look like white holes. But time doesn\u2019t run in reverse in our universe.<\/p>\n<p>To understand more, let\u2019s start by thinking about how black holes work.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Whats_a_black_hole\"><\/span>What\u2019s a black hole?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>When you drop a tennis ball, it falls to the ground due to what we call gravity. The Earth is very heavy, so it pulls the tennis ball down.<\/p>\n<p>If Earth had more material inside, making it even heavier, gravity would pull on the ball more strongly. The pull would also be stronger if we stood on the surface of a shrunken Earth, which remained as heavy as it is.<\/p>\n<p>Now, imagine we\u2019re deep space explorers and we\u2019ve found something out in space that is both extremely heavy and very small. It pulls very strongly on anything that comes close to it, so we keep our spacecraft a safe distance away.<\/p>\n<p>This mysterious object would pull so powerfully that nothing inside could escape to the outside. A spaceship with the biggest rocket boosters couldn\u2019t escape. Even a laser beam, fired straight out at the speed of light, would not make it to the outside.<\/p>\n<p>This kind of object is a black hole.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Whats_a_white_hole\"><\/span>What\u2019s a white hole?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Now imagine we stick around in our spaceship (at a safe distance) and make a movie of this black hole.<\/p>\n<p>As we watch it, we\u2019d never see anything escape the black hole. We would instead see the black hole eat anything that came too close. We get lucky: as we watch, the black hole swallows an entire star!<\/p>\n<p>Our movie, titled \u201cBlack hole eats a star\u201d gets a million views online. But now imagine if we played it in reverse. In the backwards movie, we\u2019d see a very heavy, very small object just sitting there \u2013 and then, all of a sudden, spit out an entire star!<\/p>\n<p>The object we\u2019re looking at now, which spits everything out and eats nothing, would be called a white hole.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Are_there_white_holes\"><\/span>Are there white holes?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>We have good evidence from our telescopes that black holes really do exist.<\/p>\n<p>However, we\u2019ve never seen a white hole (which is a shame, because they would be really awesome). The reason astronomers think about white holes at all is because of Albert Einstein \u2013 a great scientist who is no longer alive, but if you\u2019ve ever seen him you may remember his crazy hair.<\/p>\n<figure class=\"align-right zoomable\">\n<figure class=\"post-image post-mediaBleed aligncenter\"><img decoding=\"async\" loading=\"lazy\" sizes=\"auto, (min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px\" alt=\"Portrait of Albert Einstein in black and white.\" width=\"600\" height=\"800\" class=\"js-lazy\" src=\"https:\/\/images.theconversation.com\/files\/444221\/original\/file-20220203-17-jyvzeh.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=237&amp;fit=clip\" srcset=\"https:\/\/images.theconversation.com\/files\/444221\/original\/file-20220203-17-jyvzeh.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=800&amp;fit=crop&amp;dpr=1 600w, https:\/\/images.theconversation.com\/files\/444221\/original\/file-20220203-17-jyvzeh.jpeg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=800&amp;fit=crop&amp;dpr=2 1200w, https:\/\/images.theconversation.com\/files\/444221\/original\/file-20220203-17-jyvzeh.jpeg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=800&amp;fit=crop&amp;dpr=3 1800w, https:\/\/images.theconversation.com\/files\/444221\/original\/file-20220203-17-jyvzeh.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=1005&amp;fit=crop&amp;dpr=1 754w, https:\/\/images.theconversation.com\/files\/444221\/original\/file-20220203-17-jyvzeh.jpeg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=1005&amp;fit=crop&amp;dpr=2 1508w, https:\/\/images.theconversation.com\/files\/444221\/original\/file-20220203-17-jyvzeh.jpeg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=1005&amp;fit=crop&amp;dpr=3 2262w\"\/><figcaption><a rel=\"nofollow noopener\" target=\"_blank\" href=\"#\" data-url=\"https:\/\/twitter.com\/intent\/tweet?url=https%3A%2F%2Feditorial.thenextweb.com%2Fspace%2F2022%2F02%2F06%2Fcan-black-holes-become-white-holes-syndication%2F&amp;via=thenextweb&amp;related=thenextweb&amp;text=Check out this picture on: Much of what we know about gravity, and the way it works, is thanks to the amazing work of the scientist Albert Einstein.

His theory describes how black holes work, with their huge gravitational pull.<\/p>\n<p>Einstein\u2019s idea also says white holes are <em>possible<\/em>. So could our universe actually make a white hole? And could a black hole become a white hole? Probably not. Something can be \u201cpossible\u201d as an idea, but also extremely unlikely in real life.<\/p>\n<p>White holes are unlikely because they are an \u201cin reverse\u201d kind of thing. Think of breakfast in reverse: your egg unscrambles itself and jumps out of the pan, back into the shell. It\u2019s possible, but it would mean time had turned itself around and started running backwards.<\/p>\n<p>As best we can see and measure, time in our universe only flows in one direction: forward. So for now, white holes are just an interesting possibility.<!-- Below is The Conversation's page counter tag.
