Massive space blasts might be acting like 'pesticides' that stop aliens from ever evolving in the center of the galaxy.

The Takeaway
These massive cosmic explosions can strip the ozone layer off planets from thousands of light-years away. This study proposes that these events happen so frequently near the galactic center that they repeatedly reset biological evolution, meaning advanced life might only be possible in the quiet 'suburbs' of the galaxy where we live.
From the abstract
High-energy astrophysical events, particularly Gamma Ray Bursts (GRBs), have been proposed as significant contributors to mass extinction events on Earth-like planets in most of the galaxy, internal to our radius in it. This paper examines the extent to which GRBs may reset the evolutionary progress of complex life through repeated extinction-level disruptions. While resilient extremophiles may survive even the most intense GRBs, more complex surface-dwelling organisms are vulnerable to indirect
