  It is hypothesized that de Broglie's 'matter waves' provide a dynamical basis
for Minkowski spacetime in an antisubstantivalist or relational account. The
relativity of simultaneity is seen as an effect of the de Broglie oscillation
together with a basic relativity postulate, while the dispersion relation from
finite rest mass gives rise to the differentiation of spatial and temporal
axes. Thus spacetime is seen as not fundamental, but rather as emergent from
the quantum level. A result by Solov'ev which demonstrates that time is not an
applicable concept at the quantum level is adduced in support of this claim.
Finally, it is noted that de Broglie waves can be seen as the "bridge of
becoming" discussed by Elitzur and Dolev (2005).
