A comment on Physicists believe they can create matter from colliding photons. Parent comment
It is one of the assumptions of Einstein, namely that there is a fixed max velocity c. To get Newton's 1/2mv^2 in the Taylor expansion requires a factor c^2.
Something else would lead to measurable deviations in slowly moving objects.
