time cloak)将会问世，这将会改变颠覆人类的认知。<br><br>英国伦敦帝国理工学院的科研人员在中国科学院出版的《光学杂志》(Journal of Optics)刊登文章称，他们已证明利用标准光纤科技，<a href="http://theory.oecr.com" target="_blank" class="relatedlink">理论</a>上或令“时空斗篷”机器成为现实。不过这种新技术并非把物体转移，而是把物体的行程隐藏。<br><br>“时空斗篷”利用的原理是加速或者减慢光线传递的速度，进而给人造成错觉，使观看者无法看到一件现实中所发生的事件，达到隐藏的效果。研究员法瓦罗举了一个例子：“当一个人利用时空斗篷穿越走廊时，你如果是一位观察者，就会发现他可能会突然间从一个方位消失，而过几秒后他可能会出现在你的面前，其实是中间的过程被掩盖了，你的视觉并没有发现而已。”<br><br> <p><a href="http://www.oecr.com/data/attachment/portal/201012/06/162616ewqw68qa2ti8zq7e.jpg" target="_blank"><img

target="_blank"><img src="http://www.oecr.com/data/attachment/portal/201012/06/1626318v8uvu11scqbninh.jpg"></a></p>他同时说道，这类似于电影剪辑，一部电影的拍摄经过了很久，但是展现在我们面前的只是其中的精华部分，其他的场景根据需要都被剪辑掉了。如同《星球大战》一样，展现给人们以强烈的冲击力。<br><br>首席科学家马丁麦考尔教授说道：“时空斗篷类似于摄像机，只是时空斗篷是利用灯光<a href="http://light.oecr.com" target="_blank" class="relatedlink">照明</a>的方式达到的效果，而摄像机则是通过剪辑呈现在大众的面前，所谓的摄像机从来不撒谎是完全不正确的。”</td></tr></table> <!--[diy=diycontentbottom]--><div id="diycontentbottom"
