If we could power such an elevator with solar energy, we could simply rise up into space for a fraction of the cost of a trip by rocket or shuttle.

如果我们能利用太阳能为这样的电梯提供动力，我们只需花费乘坐火箭或航天飞机旅行费用的一小部分就能进入太空。

It is an increased area of low thick clouds, the type that reflects a rare portion of solar energy back to space and cools the Earth.

它是一片变大的低厚云层，这种云层将少量的太阳能反射回太空，为地球降温。

The energy that would be needed to probe the granularity of space is known as the Planck energy.

We also need to have something in the energy space, because of the fact we are an expanding economy.

Proposed by Mexican theoretical physicist Miguel Alcubierre in 1994, the drive would propel a ship at superluminal speeds by creating a bubble of negative energy around it, expanding space (and time) behind the ship while compressing space in front of it.
