The universe is mostly composed of things we cannot see
In short: Ancient Greek philosophers believed the cosmos was built from just four elements: earth, fire, wind, and water. Modern science has revealed a much more complex reality. Everything we can actually observe represents only a tiny fraction of the total universe, leaving a vast, invisible majority to be explained.
For centuries, the Greek understanding of the universe relied on a simple and elegant formula consisting of earth, fire, wind, and water. However, contemporary physics has overturned this elemental view. We now know that visible matter—which includes everything beyond those four classical elements—accounts for only about 4% of the entire universe. This shift represents a profound departure from ancient cosmological models. Such discoveries challenge our fundamental perceptions of reality. This transition marks a significant evolution in human thought. It highlights how much our cosmic perspective has expanded.
The remaining 96% of the cosmos is composed of two mysterious components: dark matter and dark energy. While visible matter interacts with light and can be observed through telescopes, dark matter remains elusive, making it difficult for scientists to detect directly. This massive, invisible presence is a fundamental part of the cosmic architecture. These dark components constitute the vast majority of the cosmic landscape. Their influence is felt throughout the entire structure of space. These substances remain largely undetected by current methods. Their presence is vital to the cosmic structure.
CERN scientist James Gillies explores this mystery, investigating what these invisible forces actually are and how researchers might eventually detect them. Understanding this unseen majority is essential to grasping the true composition and mechanics of our universe, moving far beyond the limited scope of the visible world. His research focuses on identifying these hidden elements. This work is crucial for modern astrophysics. He examines the nature of these hidden forces. This inquiry is vital for understanding the universe.
