2·Another showed that an atomic clock sped up when launched on a rocket 10,000 kilometres above Earth's surface, where the planet's gravitational field is weaker.
另一项研究显示，当把原子钟用于火箭，发射到离地面1万公里以上的高空时，由于那里的地球引力场较弱，而略微有所加快。
3·When we throw up an object in a gravitational field, you have the trajectory in a plane.
当我们把一个物体，放到引力场中，我们会得到在一个平面上的轨迹。
4·Thus, anything inside the event horizon, including a photon, is prevented from escaping across the event horizon by the extremely strong gravitational field.
