Let’s go on a side trail here and discuss what is entropy. And then later will discuss entropy and the universe. In the classical sense, entropy is a thermodynamic term associated with molecular disorder. entropy, the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. Because work is …
A fundamental issue with a cyclical universe is entropy, which shows even if the universe was cyclical, it could not have been eternal. A cyclic universe needs no beginning. It always was, always is, and always will be. But the model isn’t without its problems. One of the main ones is the problem of entropy. …

Note, only recently scientists have accepted the universe had a beginning. So, from a Christian perspective, it is not extraordinary that scientists is now affirming what the …

The earth is truly unique. Not only do we see design in the fundamental laws of physics, there is also design exhibited for life to exist on our planet. As we learn what is required for life to exist on any planet, we find our earth is special. In planetary astronomy and astrobiology, the Rare …
Pale Blue Dot is a famous photograph of planet Earth taken on February 14, 1990, by the Voyager 1 space probe from a record distance of about 6 billion kilometers (3.7 billion miles, 40.5 AU), as part of that day’s Family Portrait series of images of the Solar System. In the photograph, Earth’s apparent size …
To account for fine-tuning, scientists have broached their own principle of naturalism and invoked the extranatural explanation of the multiverse. “We cannot explain all the features of our universe if there’s only one of them,” says science journalist Tom Siegfried, whose book The Number of the Heavens investigates how conceptions of the multiverse have evolved …

Another example of fine-tuning is the Penrose number: According to Penrose, universes “resembling the one in which we live” populate only one part in 10^10^123 of the available phase space volume. https://plato.stanford.edu/entries/fine-tuning/ More quotes on the fine-tuning in the universe: Physicist Paul Davies has said, “There is now broad agreement among physicists and cosmologists that …
The fine-structure constant is another example of fine-tuning and design: In physics, the fine-structure constant, also known as Sommerfeld’s constant, commonly denoted by α (the Greek letter alpha), is a fundamental physical constant which quantifies the strength of the electromagnetic interaction between elementary charged particles. The definition of α in terms of other fundamental physical …
More on design found in the universe… Today, our deepest understanding of the laws of nature is summarized in a set of equations. Using these equations, we can make very precise calculations of the most elementary physical phenomena, calculations that are confirmed by experimental evidence. But to make these predictions, we have to plug in …
