As far as the universe coming into existence:
Singularity
See also: Gravitational singularity and Planck epoch
Extrapolation of the expansion of the universe backwards in time using general relativity yields an infinite densityand temperature at a finite time in the past.[18] This singularity signals the breakdown of general relativity and thus, all the laws of physics. How closely this can be extrapolated toward the singularity is debated—certainly no closer than the end of the Planck epoch. This singularity is sometimes called "the Big Bang",[19] but the term can also refer to the early hot, dense phase itself,[20][notes 1] which can be considered the "birth" of our universe. Based on measurements of the expansion using Type Ia supernovae and measurements of temperature fluctuations in the cosmic microwave background, the universe has an estimated age of 13.799 ± 0.021 billion years.[21] The agreement of these three independent measurements strongly supports the ΛCDM model that describes in detail the contents of the universe.
