becomes infinite.) It is generally accepted that the universe began at a point of singularity. When the singularity of the universe started to expand, the Big Bang occurred, which evidently began the universe. The other explanation, held by proponents such as Stephen Hawking, asserts that time did not exist when it emerged along with the universe. This assertion implies that the universe does not have a beginning, as time did not exist "prior" to the universe. Hence, it is unclear whether properties such as space or time emerged with the singularity and the known universe. Despite the research, there is currently no theoretical model that explains the earliest moments of the universe's existence (during the

Compared with cosmology

In the humanities, the distinction between cosmogony and cosmology is blurred. For example, in theology, the

, which studies the universe and its existence, but does not necessarily inquire into its origins. There is therefore a scientific distinction between cosmological and cosmogonical ideas.
