  The Ghirardi-Rimini-Weber (GRW) theory of spontaneous collapse offers a
possible resolution of the quantum measurement problem. In this theory, the
wave function of a particle spontaneously and repeatedly localises to one or
the other random position in space, as a consequence of the hypothesised
quantum jumps. In between jumps the wave function undergoes the usual
Schr\"{o}dinger evolution. In the present paper we suggest that these jumps
take place in Hilbert space, with no reference to physical space, and physical
three-dimensional space arises as a consequence of localisation of macroscopic
objects in the universe. That is, collapse of the wave-function is responsible
for the origin of space. We then suggest that similar jumps take place for a
hypothetical time operator in Hilbert space, and classical time as we know it
emerges from localisation of this time operator for macroscopic objects. More
generally, the jumps are suggested to take place in an operator space-time in
Hilbert space, leading to an emergent classical space-time.
