Well, this is how science works..
First you make assumptions (that is hypothesis) , then you do some calculations based on those assumptions (that is theory) , then you measure the outcome (this is experiment).
If the outcome of experiment confirms calculation results, theory is correct.
If not, theory is not valid.
BTW, radio waves travel exactly at speed of light (in vacuum.. because they are also electromagnetic radiation, as well as visible light, x rays, gamma rays etc ).
