Enoch was taken on a tour of the universe and shown all the pecuiiar paths of the sun, moon, stars/constellations, and planets, and how they bring in the years, days, and months, and weeks.
Biblically speaking, the sun runs its course in its ordained path in the circle of the earth/the circling heavens; and the moon follows the sun exactly in the same path/course, only falling behind in the path a certain number of days each year, until they are equal to the beginning one, again, and it starts over.
The Word of God declares that there is coming a time when the earth will one day be moved out of its place and turned upside down and jump about as a hunted roe. The seasons will be backwards and fruit will not appear in its season. Stars will fall from heaven [to earth, from whence they have their origin when God said "Let there be Light", on day one, and the electromagnetic forces of creation came out of the darkness and the "pillars of the earth" were set]. The wind and waves will rage, and great earthquakes will abound in strange places. The sun will be low on the western horizon, and will burn men on earth so that if God did not "cut short the parts of those days and nights by one third of their parts", then no flesh on earth would survive that time, which time is the Great Tribulation, coming.
