The concept of a multiverse, which suggests the existence of multiple universes beyond our own, is a speculative idea in cosmology and theoretical physics. While it is an intriguing concept, it is important to note that the existence of a multiverse is still a subject of scientific debate, and there is currently no direct empirical evidence to confirm or refute its existence.
Within the framework of certain multiverse theories, such as the "bubble universe" or "brane" models, it is possible to imagine scenarios where different universes exist alongside each other or overlap in some manner. However, the specific nature of such interactions, including the possibility of coexistence with other species in dimensions we cannot perceive, would depend on the particular multiverse theory being considered.
It is important to understand that the concept of other dimensions or realms beyond our observable universe is highly speculative, and our understanding of the nature of reality is limited by our current scientific knowledge. The existence of other universes or dimensions, and the possibility of interactions between them, remains an open question that scientists are actively investigating.
It is worth mentioning that speculative ideas and concepts related to the multiverse often go beyond the realm of empirical science and may fall into the realm of philosophy or metaphysics. While these ideas can be fascinating to explore and discuss, it is essential to distinguish between scientific theories supported by evidence and speculative concepts that currently lack empirical verification.
