Globular clusters are thought to have formed during what kind of early universe event?
Answer
Intense gravitational collapse and violent gas shockwaves
The formation environment for Globular Clusters (GCs) is believed to have been far more energetic than the processes creating Open Clusters today. GCs likely formed during a period of intense gravitational collapse and violent gas shockwaves in the nascent universe, possibly even before the host galaxy had achieved its mature spiral shape. This violent initial environment was necessary to rapidly assemble the massive amounts of material required to overcome later disruption and form such dense, long-lived objects. The resulting chemical signatures, specifically their low metallicity, reinforce that they formed before widespread nucleosynthesis had occurred across the cosmos.
