The concept of "prior to the Big Bang" is currently not well-understood or supported by scientific evidence. According to the prevailing cosmological model, known as the Big Bang theory, the universe originated from a singularity about 13.8 billion years ago. This theory describes the expansion of space and the subsequent evolution of galaxies over time.
The term "newly discovered 6 mature galaxies" is not specific enough to provide a definitive answer. However, it is important to note that scientific discoveries and our understanding of the universe are continuously evolving. there were no confirmed observations or scientific evidence suggesting the existence of galaxies that formed before the Big Bang.
The study of the early universe and the formation of galaxies is an active area of research. Astronomers use powerful telescopes and sophisticated instruments to observe distant objects and study their properties. These observations help us learn more about the early stages of galaxy formation and the evolution of the universe.
It's important to approach scientific discoveries with caution and be open to new information and theories as they emerge. Our understanding of the cosmos continues to expand, and future discoveries may shed more light on the origins and nature of the universe.
