The fastest thing in the universe is light, or more broadly, electromagnetic radiation. It travels at a constant speed, known as the speed of light, which is approximately 299,792,458* m/s. Nothing with mass can travel at or exceed this speed.
* Speed of Light = Frequency x Wavelength = 1/sqrt(e0 x er x u0 x ur), where er, relative permittivity, and ur, relative permeability of free space =1
And now, we should be proud of ourselves, as our minds can propagate faster than light.
Above all, the proudest comes when we can control it.
