Gravity!!! – From f = ma we get f/a = m then what if a is 0. You get an insight from a = sin(x) and f = x the limit x/sin(x)=m. So mass is the limit and acceleration oscillates around zero most of the time then a force must be created to follow acceleration so mass exist. // Per – super intelligence!
