The idea that we can only detect 5% of matter in the Universe is a fascinating and mind-boggling concept. However, it is important to note that the remaining 95% of matter that we cannot detect is not simply not part of the Universe. Instead, it falls under the category of what is known as dark matter and dark energy.
Dark matter is a hypothesized form of matter that does not interact with light or other electromagnetic radiation, making it extremely difficult to detect directly. Its existence is inferred through its gravitational effects on visible matter and the structure of the Universe. Scientists believe that dark matter makes up about 27% of the total matter-energy content of the Universe.
Similarly, dark energy is another mysterious component that cannot be directly observed or detected. It is believed to be responsible for the accelerating expansion of the Universe. Dark energy is estimated to make up about 68% of the total matter-energy content of the Universe.
So, while we are currently unable to directly detect or observe the majority of matter in the Universe, it does not mean that it is not part of the Universe. The existence of dark matter and dark energy is supported by various observational and theoretical evidence, including the observed motions of galaxies, the cosmic microwave background radiation, and large-scale structure formations.
Scientists continue to study and explore these phenomena in order to gain a better understanding of the fundamental nature of the Universe. The quest to unravel the mysteries of dark matter and dark energy remains one of the forefront challenges in modern astrophysics and cosmology.
