Horizon problem of the Big Bang

The horizon problem (also known as the homogeneity problem) is a cosmological fine-tuning problem within the Big Bang model of the universe. It arises due to the difficulty in explaining the observed homogeneity of causally disconnected regions of space in the absence of a mechanism that sets the same initial conditions everywhere. It was first pointed out by Wolfgang Rindler in 1956.

[Job 26:10 NIV] "He marks out the horizon on the face of the waters for a boundary between light and darkness."

[Pro 8:27 NIV] "I was there when he set the heavens in place, when he marked out the horizon on the face of the deep,"
