David Spence has written to ask:

If the Higgs Boson gives matter Mass, would the Higgs Boson also give matter Gravitational Forces?

What do you think?

The fact that Inertial and Gravitational mass always seem to be the same must be more than a coincidence - but it isn't one that we can explain today.

The Higgs field+boson is a quantum effect that gives matter Inertial Mass. However, we currently have no established theory of quantum gravity, so we don't have a quantum mechanism that would give matter Gravitational Mass.
