## Main Question or Discussion Point

I often hear from laymen who study some SR that if sth reaches the speed of light,it completely turns into energy!!!

Where did this crazy idea came from?

Any way,mass increase in SR seems really mysterious to me

E.g. when mass tends to infinity as velocity tends to c

Can someone clarify more?

Thanks
