Because you see, if there are other universes, and if those universes each have, say, a different shape for the extra dimensions, then the physical features of each universe will be different, and in particular, the amount of dark energy in each universe will be different.
因为你看， 如果有很多的其他宇宙， 而这些宇宙 每个都有不同的额外维度形状， 那么每个宇宙的物理特征将会不同， 特别是， 每个宇宙的暗能量 将会不同。
