But there are an estimated 100-400 billion stars in the Milky Way, some of which are hundreds of solar masses, not to mention the Accretion disks of black holes all kicking out radiation. That’s gotta add up to something, even with the inverse-square law fall off. The galactic core has unfathomable levels of radiation and puts out its own galactic wind, and some stars have observable bow shocks with it.
