Some physicists use cosmology to speculate heaven might lie beyond the cosmic horizon, but evidence remains elusive.

The question of where heaven might be, if it exists at all, has long belonged to theology and philosophy rather than science. Recently, however, a provocative idea from a physicist reignited debate by suggesting that concepts from modern cosmology could loosely align with ancient descriptions of heaven, pulling a spiritual question into a scientific frame.
The discussion draws on ideas about the expanding universe and the limits of observation. While the proposal has captured public attention, most scientists stress that it remains speculative and symbolic rather than evidence-based, highlighting the boundary between science and belief.
