  In the past few decades, many studies revealed that there exist some apparent
universal relations which can describe the dynamical properties in galaxies. In
particular, the radial acceleration relation (RAR) is one of the most popular
relations discovered recently which can be regarded as a universal law to
connect the dynamical radial acceleration with the baryonic acceleration in
galaxies. This has revealed an unexpected close connection between dark matter
and baryonic matter in galaxies. In this article, by following the recent
robust Galactic rotation curve analyses, we derive the Galactic RAR (GRAR) and
show for the first time that it deviates from the alleged universal RAR at more
than $5\sigma$. This provides a strong evidence to falsify the universal nature
of RAR in galaxies claimed in past studies.
