The concept of "heaven" is typically associated with religious or spiritual beliefs, and its nature and existence are matters of faith and personal interpretation. Different religions and belief systems have their own descriptions and understandings of heaven, ranging from a spiritual realm to a physical place of eternal happiness and reward.
From a scientific perspective, the existence of heaven as a physical place in another galaxy is currently not supported by empirical evidence. Our understanding of the universe is based on observations, measurements, and scientific theories that explain the natural phenomena we observe. While we have discovered numerous planets in our galaxy and beyond, there is currently no scientific evidence to suggest the existence of a specific planet designated as "heaven" in a different galaxy.
It's important to recognize that science and religion often address different aspects of human experience and understanding. Science focuses on exploring and explaining the natural world through empirical investigation, while religion and spirituality often deal with questions of meaning, purpose, and the transcendent. These are distinct realms of human inquiry, and they can coexist without necessarily conflicting with each other.
Ultimately, whether heaven is envisioned as a spiritual realm, a metaphorical concept, or a physical place in another galaxy is a matter of personal belief, faith, and interpretation.
