The missing mass is given off as energy.

缺少的质量作为能源释放了。

The best guess is that invisible particles called weakly interacting massive particles, or WIMPs, contribute all this missing mass.

暗物质是由肉眼看不见的粒子——大质量弱相互作用粒子，或称WIMP组成的。

But the missing mass has not disappeared; it has merely been transformed.

但是丢失的质量并没有消失；它只是被改造了。

This missing mass is called dark matter, and we observe that it accounts for 23 percent of the universe.

这种缺失的质量被称为暗物质，我们观察到它占宇宙的 23%。

That " missing mass" in the nucleus, known as its mass defect, is actually present in the form of energy.

原子核中的“缺失质量” ，称为质量缺陷， 实际上以能量的形式存在。

To find out how much binding energy that missing mass amounts to, you can use it as the 'm' in Einstein's formula.

要找出丢失的质量相当于多少结合能， 您可以将其用作爱因斯坦公式中的“m” 。

And since binding energy accounts for the missing mass, you can calculate it using – you guessed it! – e equals m c squared.

由于结合能解释了缺失的质量，您可以使用 - 您猜对了！ – e 等于 m c 的平方。
