那是十分令人震惊的，因为许多物理学家总是根据爱因斯坦的相对论，认为光速是宇宙速度的极限。
That's shocking, because much of modern physics relies on Einstein's theory that the speed of light is the universe's speed limit.
“这种背景下，自然中的速度极限就不一定是光速，”他说，“而实际上可能是中微子的速度。”
"With this kind of background, it is not necessarily the case that the limiting speed in nature is the speed of light," he said.
光速被广泛认为是宇宙中速度的极限。
The speed of light is widely regarded as the Universe's ultimate velocity limit.
所以说，光速可以减慢却不能加快：真空好比是自然界的康庄大道，光便以其极限速度疾驰在这条大道上。 欧洲粒子物理研究所的实验室里到底发生了什么？
So light can be slowed down, but not sped up: the vacuum is nature's open road where light travels at the speed limit.
作为时空结构的一部分，光速是终极速度极限。
The velocity of light is the ultimate speed limit, being part of the very structure of space and time.
光速限定了自然界的速率极限。
光速限定了自然界的速率极限。
