No, there isn’t a hole in the Universe

<p>Somewhere, far away, if you believe what you read, there&rsquo;s a hole in the Universe. There&rsquo;s a region of space so large and empty, a billion light-years across, that there&rsquo;s nothing in it at all. There&rsquo;s no matter of any type, normal or dark, and no stars, galaxies, plasma, gas, dust, black holes, or anything else. There&rsquo;s no radiation in there at all, either. It&rsquo;s an example of truly empty space, and its existence has been visually captured by our greatest telescopes.</p> <p>At least, that&rsquo;s what some people are saying, in a photographic meme that&rsquo;s been spreading around the internet for years and refuses to die. Scientifically, though, there&rsquo;s nothing true about these assertions at all. There is no hole in the Universe; the closest we have are the underdense regions known as cosmic voids, which still contain matter. Moreover, this image isn&rsquo;t a void or hole at all, but a cloud of gas. Let&rsquo;s do the detective work to show you what&rsquo;s really going on.</p> <p><a href="https://medium.com/starts-with-a-bang/no-there-isnt-a-hole-in-the-universe-4a00bce53b4f"><strong>Website</strong></a></p>
