The question of whether one would prefer the universe to have no beginning or end is subjective and can vary from person to person. Some individuals might find comfort in the idea of an eternal universe, as it implies a sense of permanence and continuity. Others might appreciate the concept of a universe with a beginning and an end, as it allows for change, evolution, and the potential for new beginnings.
Regarding the possibility of an eternal universe or a multiverse that has always existed, it is indeed a topic of scientific speculation and exploration. There are different cosmological models and theories that propose the idea of an eternal universe or a multiverse with no definitive starting point. These models often involve complex mathematical frameworks, such as certain variations of the cyclic universe model or the concept of a multiverse arising from quantum fluctuations.
However, it's important to note that our current scientific understanding is based on the available evidence and observations, and the prevailing cosmological model is the Big Bang theory, which suggests a finite age for our observable universe. While the concept of an eternal universe or a multiverse is intriguing and worthy of investigation, it is essential to subject these ideas to empirical testing and gather evidence to support them.
Scientific progress and new discoveries continually shape our understanding of the universe, so it is always possible that future observations and theories may shed further light on the nature of existence, including the question of whether the universe has always existed or not.
