  In this invited response we answer all comments by Engelen and Hansen
[arXiv:2207.07844]. We point out that the superfluid and superconductive
properties of H(0) have been published previously. We explain some differences
between covalently bonded molecules and the molecules in the ultradense matter
H(0) form, and explain some aspects of the energetics of H(0) molecules during
Coulomb explosions. We point out that the experimental spectra shown in our
publication are not ion time-of-flight spectra but neutral time-of-flight
spectra with the peak width given by the internal energetics and not by
experimental factors. We point out that no phase diagram has been measured for
H(0). Further we point out that a Rydberg state is a hydrogenic state and thus
that all hydrogen atom states are Rydberg states. That Rydberg states always
have large principal quantum numbers is a complete misunderstanding. We point
out that a QM description of H(0) is published. We point out that the
internuclear distances in p(0), D(0) and pD(0) have been measured by rotational
spectroscopy in two publications for three different spin states. They are
measured in the pm range with fm precision.
