comment Why aren't units with powers, like cm³, surrounded by parentheses?
Well, $1\text{ dm}^3 = 1\text{ dm}^3 \cdot 1\text{ dm}^3 \cdot 1\text{ dm}^3$, but obviously $2\text{ dm}^3 \neq 2\text{ dm}^3 \cdot 2\text{ dm}^3 \cdot 2\text{ dm}^3$. It might be a better idea to say e.g. $4\text{ dm}^3 = 4 \cdot 1\text{ dm}^3 \cdot 1\text{ dm}^3 \cdot 1\text{ dm}^3$.

comment What happens to body chemistry at the speed of light?
@magneticMonster You’re thinking of velocity addition the “usual” way: if you’re in a bus going 30 mph and you throw a ball forward at 10 mph then the ball will be going 40 mph according to someone outside the bus. But it turns out that this isn’t quite correct when you’re going at speeds ~10% or more the speed of light: the velocities have to add so that nothing goes faster than light. See e.g. this for more info.
