五维黑洞“黑环”可能存在
<p>黑洞的存在已经随着引力波信号的直接观测再次得到了确凿无疑的证明。而在科学家们的脑海中，他们认为宇宙中可能还存在着一种非常特殊类型的黑洞，即所谓的“黑环”。</p><p><span word="Researchers">Researchers</span> <span word="have">have</span> <span word="shown">shown</span> <span word="how">how</span> <span word="a">a</span> <span word="bizarrely">bizarrely</span> <span word="shaped">shaped</span> <span word="black">black</span> <span word="hole">hole</span> <span word="could">could</span> <span word="cause">cause</span> <span word="Einstein">Einstein</span>'<span word="s">s</span> <span word="general">general</span> <span word="theory">theory</span> <span word="of">of</span> <span word="relativity">relativity</span> <span word="to">to</span> <span word="break">break</span> <span word="down">down</span>.</p><p>请看相关报道：</p><p><span word="In">In</span> <span word="a">a</span> <span word="study">study</span> <span word="published">published</span> <span word="in">in</span> <span word="Physical">Physical</span> <span word="Review">Review</span> <span word="Letters">Letters</span>, <span word="researchers">researchers</span> <span word="from">from</span> <span word="the">the</span> <span word="UK">UK</span> <span word="simulated">simulated</span> <span word="a">a</span> <span word="black">black</span> <span word="hole">hole</span> <span word="in">in</span> <span word="a">a</span> “5<span word="D">D</span>” <span word="universe">universe</span> <span word="shaped">shaped</span> <span word="like">like</span> <span word="a">a</span> <span word="thin">thin</span> <span word="ring">ring</span>. <span word="The">The</span> <span word="hole">hole</span> <span word="named">named</span> <span word="the">the</span> <span word="black">black</span> <span word="ring">ring</span> <span word="was">was</span> '<span word="discovered">discovered</span>' <span word="by">by</span> <span word="theoretical">theoretical</span> <span word="physicists">physicists</span> <span word="in">in</span> 2002.</p><p>英国研究人员近日在《物理评论快报》上发表了一项研究，他们模拟了在五维空间下的一种黑洞，这种黑洞形如细环，又称“黑环”。理论物理学家最早在2002年提出了相关设想。</p><p>这里的“黑环”（<span word="black">black</span> <span word="ring">ring</span>）是指环状的黑洞，是一种特殊的黑洞模型，科学家们认为此类型黑洞处于五维甚至更高维度空间中（<span word="exist">exist</span> <span word="in">in</span> <span word="a">a</span> <span word="universe">universe</span> <span word="with">with</span> <span word="five">five</span> <span word="or">or</span> <span word="more">more</span> <span word="dimensions">dimensions</span>）。</p><p>尽管黑环早在2002年就被理论物理学家们“发现”，但在此次研究中才第一次成功使用超级计算机对其进行动态模拟（<span word="dynamic">dynamic</span> <span word="simulation">simulation</span>）。</p><p>参与相关研究的科学家们表示，如果这类特殊黑洞的确存在，那么它将导致“裸奇点”（<span word="naked">naked</span> <span word="singularity">singularity</span>）的存在，从而最终打破爱因斯坦的相对论体系（<span word="Einstein">Einstein</span>'<span word="s">s</span> <span word="theory">theory</span> <span word="of">of</span> <span word="relativity">relativity</span>）。英国著名物理学家史蒂芬•霍金曾经表示：大自然厌恶裸奇点（<span word="nature">nature</span> <span word="abhors">abhors</span> <span word="a">a</span> <span word="naked">naked</span> <span word="singularity">singularity</span>），因为那将打破我们对于宇宙规则的全部认识。</p>
