When traveling at the speed of light, it exhibits particle
properties. It has been about half a century since experiments
proved that light waves are bent by gravity thus proving that
electromagnetic radiation has mass. That idea was postulated
in 1915. Did you get your degree before then? :-)

You say the "idea was postulated in 1915." Since when does a postulate
become proof making something a law?

It was postulated by Einstein in 1915 and measurements
agreed in 1919. It is said to have been proven a scientific
fact in 1959. I'm just surprised that your university didn't
teach it in the postulate stage, valid measurement stage, or
in the scientific fact stage. :-)
