To the astonishment of the entire world, the neutrinos clocked in 60 nanoseconds sooner than a lightbeam traveling the same distance would have done.
他们记录到的中微子的行驶时间要比光线行驶相同距离提早了60纳秒，从而使整个世界为之震惊。

Because light travels in a straight line through the contours of space-time, a lightbeam will curve where space-time curves, this curving was first measured in 1919.
因为光沿时空走直线，所以光线在时空弯曲的地方会弯曲。这现象在1919年首次被观测到。

When the laser hits the photovoltaic device, the photons in the lightbeam are converted to electricity in the same way that solar cells convert sunlight into electricity.
