 To calculate the **mass of a photon**, take the energy of the photon and divide it by the speed of
 light squared. However, in practice, photons are considered to have zero mass.
 
-In this task, you need to identify magic numbers in the code and create constant values for them.

 _The speed of light_ is the ultimate speed limit in the universe, and it's a constant, never changing.
-It's so fast that light can zip around the Earth over 7 times in just one second! And nothing can go faster than that.
