Einstein's famous equation, E=mc2, outlines how energy is equivalent to mass times the square of the speed of light.

这个道理可以参考著名的爱因斯坦质能方程式，E=mc2, 能量E是质量m乘以光速c的平方项。

The light parts of the equation (within parenthesis) is repeated for all lights that hit the object.

在括号中的那部分光线计算，是计算所有照射到物体上的光线。

Gravitational particles are moving Ether particles in high-speed, the gravitational field spread much faster than the speed of light, Newton's gravitational equation was amended.

引力粒子是高速运动的以太粒子，引力场的传播速度远远超过光速，牛顿的引力方程得到修正。

And the reason is, and this will come up on the problems and a lot of students end up using this equation, which is why I want to head it off and mention it ahead of time, we can't use an equation because this equation is very specific for light.

原因是，很多同学在解题时,都会用这个方程，所以我要,事先提醒你们一下,我们不能用这个方程，因为它只对光是用。

That makes sense because we're losing energy, we're going to a level lower level, so we can give off that extra in the form of light. And we can actually write the equation for what we would expect the energy for the light to be.

这很合理，因为我们在损失能量,我们要到一个更低的能级去,我们要以光的形式给出额外的能量,我们可以写下光能量的方程。

c We know it's very specific for light because in this equation is c, the speed of light. So any time you go to use this equation, if you're trying to use it for an electron, just ask yourself first, does an electron travel at the speed of light?

我们知道它只对光适用是因为在这个方程里有,光速，所以下次你们用这个方程前，如果你们要把它用到一个电子上，先问问你自己，电子的运动速度是光速吗？
