Both perspectives you mentioned involve aspects that are currently speculative or not fully understood. It's important to approach these topics with an open mind and acknowledge the limitations of our current knowledge.
In option (1), proposing that time is eternal and infinite, and that a multiverse exists, is based on certain theoretical frameworks such as eternal inflation or string theory. These ideas attempt to explain the origins and properties of the universe beyond the observable universe. While they are intriguing and have some theoretical support, they currently lack direct empirical evidence. They remain active areas of research and exploration.
In option (2), suggesting that time "magically" popped into existence 13.8 billion years ago after the Big Bang and nothing caused or preceded it is not an accurate representation of the current scientific understanding. The Big Bang theory, supported by substantial observational evidence, describes the early expansion of the universe from an extremely hot and dense state. However, the theory does not explain what caused the Big Bang or what might have preceded it. Our understanding of the origins of the universe is an active area of research, and scientists are actively investigating theories such as cosmic inflation and quantum gravity to provide further insights.
It's important to note that ideas about the nature of time, the origins of the universe, and the existence of a multiverse are deeply complex and not fully resolved. Both options you mentioned involve aspects that are currently speculative or the subject of ongoing scientific inquiry. As our understanding evolves and more evidence becomes available, our perspectives on these topics may change.
