If this measurement had agreed with expectations, and showed neutrinos travelling at or below lightspeed, how carefully would we be examining the uncertainties?
如果实验结果与预期相符,并显示中微子以光速或低于光速的速度前进,我们会有多小心的检查不确定性呢?

But, Schmidt says, the combo antimatter fusion engine could not likely generate the thrust needed to get up to seven-tenths lightspeed.
不过施密特也指出,混合反物质聚变发动机产生的推力很可能达不到所需的7/10光速。

Scientists have come up with a much more accurate way of measuring distance - wavelengths and lightspeed.
