Nothing in the Universe can move faster than 300,000 kilometers per second (186,000 miles per second) \u2013 and nothing with mass can reach that speed.<\/p>\n<p>There are, however, theoretical workarounds and loopholes, which have to do with the fact that the very fabric of space-time itself can warp and bend. There&#8217;s the notion of\u00a0wormholes, or\u00a0Einstein-Rosen bridges: shortcuts created by folding space-time.<\/p>\n<p>And then there&#8217;s the\u00a0warp drive, or\u00a0Alcubierre drive, a hypothetical engine that can create warps in space-time that circumvent the speed limit. It would work by squeezing space in the fore and expanding it aft, like toothpaste in a tube, thus shrinking the amount of space to be traveled and allowing some hypothetical craft to traverse the distance faster than if space-time had been left alone.<\/p>\n<div class=\"aspect-w-16 aspect-h-9 youtube-iframe relative\"><iframe src=\"https:\/\/www.youtube.com\/embed\/A2JCoIGyGxc?feature=oembed\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\" data-mce-fragment=\"1\"><\/iframe><\/div>\n<p>For obvious reasons, this is not something humanity has been able to achieve. But an international group of scientists called Applied Physics has been\u00a0theorizing\u00a0about how it might work \u2013 and now they think they have a new solution, what they call the\u00a0constant velocity warp drive.<\/p>\n<p>&#8220;This study changes the conversation about warp drives,&#8221;\u00a0says physicist Jared Fuchs\u00a0of Applied Physics, who did his PhD at the University of Alabama in Huntsville.<\/p>\n<p>&#8220;By demonstrating a first-of-its-kind model, we&#8217;ve shown that warp drives might not be relegated to science fiction.&#8221;<\/p>\n<p>When Mexican theoretical physicist Miguel Alcubierre\u00a0proposed his warp drive in 1994, it had a significant drawback. It required a bubble of negative energy density around an object to create the imbalance in space-time, powered by either exotic particles that we haven&#8217;t yet discovered, or the mysterious\u00a0dark energy\u00a0that drives the expansion of the Universe.<\/p>\n<p>This is not even remotely achievable, currently or maybe ever, but there&#8217;s something else that can warp space-time \u2013 and that&#8217;s gravity.<\/p>\n<p>Previous work at Applied Physics\u00a0described\u00a0how developing a super-powerful gravitational field could squeeze space-time, whilst keeping the drive well within the bounds of known (if extremely difficult to pull off) physics.<\/p>\n<p>The think tank&#8217;s latest work focuses on a similar solution, theorizing a warp drive that can manipulate space-time to behave as though reacting gravitationally to normal matter.<\/p>\n<p>It consists of a stable shell of matter with,\u00a0as the researchers describe, a &#8220;modified shift vector on its interior&#8221;. The resulting warp &#8216;bubble&#8217;, pictured below, would send a spacecraft through space at speeds lower than that of light, but it could, the researchers say, work without needing exotic energy sources.<\/p>\n<figure id=\"attachment_126786\" class=\"wp-caption alignnone\" aria-describedby=\"caption-attachment-126786\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-126786\" src=\"https:\/\/www.sciencealert.com\/images\/2024\/05\/warp-drive.jpg\" sizes=\"auto, (max-width: 642px) 100vw, 642px\" srcset=\"https:\/\/www.sciencealert.com\/images\/2024\/05\/warp-drive.jpg 642w, https:\/\/www.sciencealert.com\/images\/2024\/05\/warp-drive-533x415.jpg 533w, https:\/\/www.sciencealert.com\/images\/2024\/05\/warp-drive-600x467.jpg 600w\" alt=\"\" width=\"642\" height=\"500\" \/><figcaption id=\"caption-attachment-126786\" class=\"wp-caption-text\">An illustration of the warp drive concept.
