Einstein’s famous equation, E = mc², isn’t just for physicists; it’s for all of us curious cats. 🐱 Let’s dive into the world of energy, mass, and the speed of light in a way that even the most energy-efficient light bulb would envy!

**Formula for E = mc²**:

```
E = m * c**2
```

Where:

`E`

is the energy.`m`

is the mass.`c`

is the speed of light.
