-the [big bang theory] is the prevailing [cosmological description] of the [development] of the [universe]–
.
(under this theory, ‘space’ + ‘time’ emerged together 13.799±0.021 billion years ago with a fixed amount of ‘energy’ + ‘matter’ that has become less ‘dense’ as the ‘universe’ has expanded)
(“…falling further and further behind…”)
.
(after the initial ‘expansion’, the ‘universe’ cooled, allowing the first ‘sub-atomic particles’ to form – which created simple ‘atoms’)
.
[giant ‘clouds’ later merged through ‘gravity’ to form…]
‘stars’
‘galaxies’
(…and everything else ‘seen’ today!)
