If I rotate this faster than in two seconds when the bucket is upside-down if physics works, the water should not fall out.
如果我旋转的速度比桶倒过来的两秒钟还快,要是物理原理成立,水就不会掉出来。
So if I rotate this faster than in two seconds when the bucket is upside-down if physics works, the water should not fall out.
因此,如果甩一圈小于两秒,就算水桶倒过来,如果物理定律都发挥作用,水就不会倒出来。
As this gas cools, it can fall toward the galaxy's center where it should continue to cool even faster and form new stars.
当气体冷却,它会坠入星系的中心。在那里,气体会继续冷却甚至可能加速变凉而形成恒星。
