One of the most fascinating facts about science is that approximately 74% of the universe is composed of dark energy, a mysterious force that accelerates the expansion of the universe. This enigmatic energy does not emit, absorb, or reflect light, making it invisible and detectable only through its gravitational effects on visible matter. In addition to dark energy, about 22% of the universe is made up of dark matter, which also cannot be seen directly but plays a crucial role in the structure and formation of galaxies. Together, these two components make up around 96% of the universe, leaving only about 4% for the ordinary matter that forms stars, planets, and living organisms. This highlights a profound mystery in cosmology, as scientists strive to understand the nature of dark energy and dark matter, which remain some of the universe's greatest unknowns.
