I got confused.. XD

"Under Einstein's theory of relativity, an object accelerated close to the speed of light gains a tremendous amount of mass.That is why no amount of energy can suffice to accelerate any object, even an elementary particle, to the speed of light - it becomes infinitely massive at the limit."

Photons are elementary particles that compose light. But as it travels at the speed of 3x10^8 m/s, i don't think it gain tremendous amount of mass, because light as we know is massless.

Please help. I got confused.

Thanks,
