You lost me at the letter 'R'...
A relativistic physicist is essentially a job studying time dilation, the properties of light, and the highest speeds that matter can travel. Albert Einstein laid the groundwork of this career in his famous equation e=mc^2 (energy equals mass times the speed of light squared), which I'm sure that more than half of the people who say it have no idea what it means.
What's the outlook?
The outlook from 2012 to 2020 is expected to be 10%, and the wages for 2012 are a median of $106,360 per year.
Imagining 3D space as 2D as to be able to comprehend time (4D) as 3D.
Again, 4D is represented as 3D to show that time can bend space in our favor.

Speed is measured in fractions of the speed of light.
What do you need to have?
The requirements for a physicist almost always include a Doctorate's Degree in some form of physics, and any other degrees in similar scientific fields help too. (Ex. Biology Degree for Biophysics)
