Cosmogony facts for kids
Cosmogony is any theory of the origin of the universe.
In astronomy, cosmogony is the study of the origin of things like the universe, the Solar System, or the Earth–Moon system. The popular cosmological model for the birth of the universe is the Big Bang theory.
It is generally accepted that the universe began as a singularity, and when the singularity of the universe started to expand, the Big Bang occurred, which began the universe.
People disagree on the origins of the singularity.
Others like Stephen Hawking say "time" did not exist and was only born with the universe. Hence the universe does not have an origin story. Time did not exist before the creation of the universe.
There is currently no theoretical model that explains the earliest moments of the universe's existence (during the Planck time). This is because we lack a testable theory of quantum gravity. Still, some researchers in string theory, M theory, and loop quantum cosmology have some ideas.
- a supreme being or god
- birth via sex between male and female gods
- or birth via the cosmic egg
It is not the same as cosmology
Cosmology studies the universe in general. You can still study the universe without thinking about its origin, which is what cosmonogy studies specifically.

Projection of a Calabi–Yau manifold from string theory. In quantum physics, there remain different, plausible theories regarding what combination of "stuff", space, or time emerged along with the singularity (and therefore this universe). The main disagreement among theories is whether time existed "before" the emergence of our universe.
