The blast wave circled the globe three times.

爆炸波环绕地球三圈。

Blasting out these waves takes energy.

爆发这些波浪需要能量。

As the blast wave collides with the outer layers of the star, it generates the highest temperatures in the universe, 100 billion degrees.

随着冲击波与恒星外层的碰撞，宇宙中最高温度的记录产生了 一千亿摄氏度。

In a second, a fireball 50 kilometers across vaporizes everything in its way, and creates a blast wave that flattens 3,000 square kilometers of forest.

一秒钟内，爆炸产生一个直径为50公里的火球，所经之处都被蒸发，产生了一股冲击波可将3000平方公里的森林夷为平地。

There's a really big difference in how the blast wave behaves from a bomb that's right on the ground from one that's a little bit in the air.

地面上的炸弹和空中的炸弹在冲击波的表现上有很大的不同。

What you're seeing here is the complex interaction that happens when the blast wave hits the ground, goes straight down, bounces back up, and then intersects with that blast wave coming out.

你现在看到的是一种复杂的相互作用，当冲击波接触地面，直线下降，反弹回来，然后与冲击波相交。
