Such a thing is not within the realm of possibility.

这种事属于不可能的范围。

A collapse in stock markets, a surge in unemployment, panic throughout the global economy, all are firmly within the realm of possibility.

股市崩盘、失业率飙升、全球经济陷入恐慌，这一切都有可能发生。

The base of the cube would only be about five times larger than the Tesla giga-factory as well, so building the cube is certainly within the realm of possibility.

这个立方体的底座也只有特斯拉超级工厂的五倍大，所以建造这个立方体当然是有可能的。
