Radial velocity, also known as the Doppler wobble technique, involves searching for wobbles in a star's light that indicate the gravitational pull of an orbiting planet.

径向速度法，也被称为多普勒摆动技术，用于搜索恒星光线的摆动，它显示出来自轨道上运行的行星的万有引力。

Radial velocity is a planet-hunting technique that looks for wobbles in a star's light, which can indicate the gravitational tugs of orbiting worlds.

径向速度是一项搜寻行星技术，可以通过寻找恒星光线的摆动。

The velocity of light is the ultimate speed limit, being part of the very structure of space and time.

作为时空结构的一部分，光速是终极速度极限。

The theory explained that space is relative and not constant, and the only thing that is constant is the velocity of light.

Entities like ARPA-E and Ultra Light Start-Ups serve to increase the velocity of that change, by exposing good ideas to financial backing and experienced management.
