The Sycamore Leaves Have Fallen and the Geese Are Flying South

The universe will continue to expand. When it expands to a certain extent, it will begin to shrink until it returns to its original shape, and then expand again and again until eternity. When the universe expands and collapses every time, everything you have experienced will appear again, again and again, and again. If the long billions of years are not used as a parameter to measure, in fact, the development of the universe is just your death again and again, or just the death of all living beings again and again.
