Return of the Cosmic Crash!

Think back to those thrilling school days when you were taught that there were three main beliefs about the universe in the secular science industry. The most popular is the heavily-Frankensteined Big Bang, which violates scientific laws. Another unscientific idea was the steady-state universe that continually replenished itself.

The cyclic or oscillating model presents the idea that the universe goes way out, slows down, then collapses in on itself, setting up another Big Bang. It keeps on a-trucking back and forth. Now a "new" idea has been proposed using the also-unscientific oscillating model.

Three main ideas of cosmogony are unscientific. Some secularists want to bring back a form of the oscillating universe, where it keeps trucking back and forth, expanding and contracting, due to lack of dark energy.

In their efforts to deny the Creator and evidence of a young universe (at least, younger than is convenient to atheistic materialism), Big Bang proponents utilize things like dark matter and dark energy. Those things cannot be detected, scientists have no idea how to do it, and by building tall tale upon tall tale, they assume dark energy decays over time. After millions of years, the universe will begin to collapse because the necessary dark energy won't be there. Then cosmic and biological evolution can begin again. People get paid for Making Things Up™ and passing it off as serious science.
According to an article in Live Science, the “oscillating universe” might be coming back in vogue. A paper in PNAS by Paul Steinhardt, Director of the Princeton Center for Theoretical Science at Princeton University in New Jersey, and two of his colleagues, Cosmin Andrei and Anna Ijjas, have announced that, in contrast to the previous view, the expansion of the universe will soon cease. By ‘soon’ they mean “remarkably quickly” in astronomical terms, which is in “the next 65 million years — then, within 100 million years, the universe could stop expanding altogether, and instead it could enter an era of slow contraction that ends billions of years from now with the death — or perhaps the rebirth — of time and space.”
