Galaxies are Born

Current observations, such as those of GN-z11, suggest that galaxy formation began as early as 400 million years after the Big Bang. This galaxy, observed at a redshift of z=11.09, stands as a testament to the rapidity with which the universe’s first structures began to coalesce from the primordial gas. While the detection of GN-z11 provides empirical evidence of early galaxy formation, it also opens the door to speculation about even earlier galaxies that may await discovery with future advancements in telescope technology. These first galaxies likely did not have black holes at their centers. From a distant observation, these early galaxies likely lacked the pronounced bright centers associated with supermassive black holes, which are characteristic of many galaxies observed 13.8 billion years after the Big Bang.
