This isn\u2019t science fiction\u2014it\u2019s the theoretical description of cosmic strings, structures that may hold answers to the Universe\u2019s greatest mysteries. If confirmed, researchers believe these theoretical strings could unlock the key to time travel.<\/p>\n<p>Cosmic strings, if they exist, are thought to be incredibly slender. Some say they\u2019d be long tubes, either stretching infinitely or looping back on themselves. Despite their thinness, a cosmic string\u2019s mass could rival tens of thousands of stars, and it would gradually shrink over time, radiating gravitational waves as it \u201cwiggles.\u201d<\/p>\n<p>Physicists have proposed two types of cosmic strings thus far. The first, \u201ccosmic superstrings,\u201d stems from string theory, a framework suggesting the Universe\u2019s fundamental particles are vibrating strings. Superstrings could be stretched across the cosmos, providing clues about the fabric of reality and possibly holding the key to time travel, too.<\/p>\n<figure class=\"is-wp-image-block wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"2400\" height=\"1350\" src=\"https:\/\/bgr.com\/wp-content\/uploads\/2022\/06\/AdobeStock_271154436.jpeg?quality=82&amp;strip=all\" alt=\"space-time warps around a wormhole\" class=\"is-wp-image-block wp-image-6015489\" srcset=\"https:\/\/bgr.com\/wp-content\/uploads\/2022\/06\/AdobeStock_271154436.jpeg?quality=82 2400w, https:\/\/bgr.com\/wp-content\/uploads\/2022\/06\/AdobeStock_271154436.jpeg?resize=150%2C84&amp;quality=82 150w, https:\/\/bgr.com\/wp-content\/uploads\/2022\/06\/AdobeStock_271154436.jpeg?resize=300%2C169&amp;quality=82 300w, https:\/\/bgr.com\/wp-content\/uploads\/2022\/06\/AdobeStock_271154436.jpeg?resize=768%2C432&amp;quality=82 768w, https:\/\/bgr.com\/wp-content\/uploads\/2022\/06\/AdobeStock_271154436.jpeg?resize=1024%2C576&amp;quality=82 1024w, https:\/\/bgr.com\/wp-content\/uploads\/2022\/06\/AdobeStock_271154436.jpeg?resize=1536%2C864&amp;quality=82 1536w, https:\/\/bgr.com\/wp-content\/uploads\/2022\/06\/AdobeStock_271154436.jpeg?resize=2048%2C1152&amp;quality=82 2048w, https:\/\/bgr.com\/wp-content\/uploads\/2022\/06\/AdobeStock_271154436.jpeg?resize=178%2C100&amp;quality=82 178w, https:\/\/bgr.com\/wp-content\/uploads\/2022\/06\/AdobeStock_271154436.jpeg?resize=190%2C107&amp;quality=82 190w, https:\/\/bgr.com\/wp-content\/uploads\/2022\/06\/AdobeStock_271154436.jpeg?resize=260%2C146&amp;quality=82 260w, https:\/\/bgr.com\/wp-content\/uploads\/2022\/06\/AdobeStock_271154436.jpeg?resize=360%2C203&amp;quality=82 360w, https:\/\/bgr.com\/wp-content\/uploads\/2022\/06\/AdobeStock_271154436.jpeg?resize=380%2C214&amp;quality=82 380w, https:\/\/bgr.com\/wp-content\/uploads\/2022\/06\/AdobeStock_271154436.jpeg?resize=389%2C219&amp;quality=82 389w, https:\/\/bgr.com\/wp-content\/uploads\/2022\/06\/AdobeStock_271154436.jpeg?resize=510%2C287&amp;quality=82 510w, https:\/\/bgr.com\/wp-content\/uploads\/2022\/06\/AdobeStock_271154436.jpeg?resize=520%2C293&amp;quality=82 520w, https:\/\/bgr.com\/wp-content\/uploads\/2022\/06\/AdobeStock_271154436.jpeg?resize=600%2C338&amp;quality=82 600w, https:\/\/bgr.com\/wp-content\/uploads\/2022\/06\/AdobeStock_271154436.jpeg?resize=720%2C405&amp;quality=82 720w, https:\/\/bgr.com\/wp-content\/uploads\/2022\/06\/AdobeStock_271154436.jpeg?resize=778%2C438&amp;quality=82 778w, https:\/\/bgr.com\/wp-content\/uploads\/2022\/06\/AdobeStock_271154436.jpeg?resize=1020%2C574&amp;quality=82 1020w, https:\/\/bgr.com\/wp-content\/uploads\/2022\/06\/AdobeStock_271154436.jpeg?resize=75%2C42&amp;quality=82 75w\" sizes=\"auto, (max-width: 2400px) 100vw, 2400px\"\/><span class=\"image-meta block clearfix\"><span class=\"source right\">Image source: rost9 \/ Adobe<\/span><\/span><\/figure>\n<p>The second type of cosmic string is believed to be a relic from the <a href=\"https:\/\/bgr.com\/science\/scientists-found-a-new-way-to-show-us-how-the-early-universe-formed\/\">formation of the early Universe<\/a>.

Richard Gott discovered that two cosmic strings moving close to light speed could theoretically form a loop in space-time, acting as <a target=\"_blank\" rel=\"noreferrer noopener\" href=\"https:\/\/bgr.com\/science\/wormholes-time-travel-theory\/\">a wormhole of sorts<\/a>, which could be the key we need to unlock time travel.<\/p>\n<p>But spotting cosmic strings is no simple task, which is why they remain so elusively theoretical to this day. Their extreme density should bend space-time, producing a lensing effect that could cause duplicate images of galaxies. However, recent findings suggest these strings might be lighter than previously thought.<\/p>\n<p>That would make them even harder to detect on a large scale, which is why some astrophysicists have proposed an alternative approach: observing \u201cmicrolensing\u201d in individual stars, where a passing string might temporarily double a star\u2019s brightness, giving us a clue as to how to find the elusive keys to unlocking <a href=\"https:\/\/bgr.com\/science\/this-physicist-says-paradox-free-time-travel-is-plausible\/\" target=\"_blank\" rel=\"noreferrer noopener\">paradox-free time travel<\/a>.<\/p>\n<\/p><\/div>\n<p><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3711241968723425\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-format=\"fluid\"\r\n     data-ad-layout-key=\"-fb+5w+4e-db+86\"\r\n     data-ad-client=\"ca-pub-3711241968723425\"\r\n     data-ad-slot=\"7910942971\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><br \/>\n<br \/><div data-type=\"_mgwidget\" data-widget-id=\"1660802\">\r\n<\/div>\r\n<script>(function(w,q){w[q]=w[q]||[];w[q].push([\"_mgc.load\"])})(window,\"_mgq\");\r\n<\/script>\r\n<br \/>\n<br \/><a href=\"https:\/\/bgr.com\/science\/physicists-think-they-may-know-the-key-to-unlocking-time-travel\/\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Imagine a thread so thin it\u2019s invisible to the naked eye but packed with the mass of thousands of stars.
