This is from the introduction of my book, Unraveling the Universe’s Mysteries.

The Twentieth Century stands as the golden age of science, yielding more scientific breakthroughs than any previous century. Yet, in the wake of all the scientific breakthroughs over the last century, profound mysteries emerged. To my eye, there appears a direct correlation between scientific discoveries and scientific mysteries. Often, it appears that every significant scientific breakthrough results in an equally profound mystery. I have termed this irony of scientific discovery the Del Monte Paradox, namely:

Each significant scientific discovery results in at least one profound scientific mystery.

I’ll use two examples to illustrate this paradox. For our first example, consider the discovery of the Big Bang theory. We will discuss the Big Bang theory in later chapters. For this discussion, please view it as a scientific framework of how the universe evolved. While the scientific community generally accepts the Big Bang theory, it is widely acknowledged that it does not explain the origin of the energy that was required to create the universe. Therefore, the discovery of the Big Bang theory left science with a profound mystery. Where did the energy originate to create a Big Bang? This is arguably the greatest mystery in science, and currently an area of high scientific focus. For the second example, consider the discovery that the universe’s expansion is accelerating. This leaves us with another profound mystery. What is causing the universe’s expansion to accelerate? Numerous theories float within the scientific community to explain these mysteries. None has scientific consensus.
