| Hong Kong physicists say they have proved that a single photon obeys Einstein's theory that nothing can travel faster than the speed of light -- demonstrating that outside science fiction, time travel is impossible, AFP reports. |
據(jù)法新社報(bào)道，香港物理學(xué)家表示，他們已經(jīng)證實(shí)單個(gè)光子遵守愛因斯坦的理論，即沒(méi)有任何物體可超越光速。這證明了在科幻小說(shuō)之外，時(shí)間旅行是不可能的。 |
| The Hong Kong University of Science and Technology research team led by Du Shengwang said they had proved that a single photon, or unit of light, "obeys the traffic law of the universe just like classical EM (electromagnetic) waves." |
香港科技大學(xué)的科研小組由杜勝望帶領(lǐng)，他們表示已證實(shí)單個(gè)光子，即光的基本粒子“跟一般的電磁波同樣都遵守宇宙交通法則”。 |
| "By showing that single photons cannot travel faster than the speed of light, our results bring a closure to the debate on the true speed of information carried by a single photon," Du said. "Our findings will also likely have potential applications by giving scientists a better picture on the transmission of quantum information." |
杜勝望說(shuō)：“我們證實(shí)了單光子速度不能超越光速，平息了過(guò)去有關(guān)單光子速度的爭(zhēng)論；從應(yīng)用層面來(lái)看，這項(xiàng)研究結(jié)果亦將加深科學(xué)家們對(duì)量子訊息傳播的理解?！?/td>
