Last of Universe's Missing Ordinary Matter
The universe is a vast expanse of space and time, filled with countless mysteries waiting to be uncovered. One such mystery has been the missing ordinary matter in the universe. Scientists have long known that the universe contains dark matter and dark energy, but they have struggled to locate the remaining ordinary matter. However, recent research has revealed that scientists may have finally found the last of the universe's missing ordinary matter.
What is Ordinary Matter?
Ordinary matter is the stuff that makes up everything we see around us, from stars and planets to people and animals. It is made up of atoms, which are composed of protons, neutrons, and electrons. This matter interacts with light and other forms of electromagnetic radiation, making it visible to us.
The Missing Ordinary Matter
Despite knowing that ordinary matter makes up about 5% of the universe, scientists have only been able to locate about half of it. The rest has remained elusive, leading to much speculation and debate among scientists.
The Search for Missing Matter
Scientists have been searching for the missing ordinary matter for decades using a variety of methods. One such method involves studying the cosmic microwave background radiation (CMB), which is leftover radiation from the Big Bang. By analyzing this radiation, scientists can determine how much ordinary matter should be present in the universe.
The Latest Discovery
Recently, scientists at the Institute of Space Astrophysics in France used data from the European Space Agency's Planck satellite to locate the last of the missing ordinary matter. They found that it was located in filaments of hot gas that connect galaxies together in a vast cosmic web.
Implications of the Discovery
The discovery of the last of the missing ordinary matter has significant implications for our understanding of the universe. It confirms our current model of cosmology and provides new insights into how galaxies form and evolve over time.
Conclusion
The discovery of the last of the universe's missing ordinary matter is a significant achievement for scientists. It provides new insights into the workings of the universe and confirms our current understanding of cosmology. As we continue to explore the mysteries of the universe, we can only hope that more discoveries like this will be made.
FAQs
1. What is dark matter?
Dark matter is a type of matter that does not interact with light or other forms of electromagnetic radiation, making it invisible to us. It is believed to make up about 27% of the universe.
2. What is dark energy?
Dark energy is a mysterious force that is causing the expansion of the universe to accelerate. It is believed to make up about 68% of the universe.
3. How was the last of the missing ordinary matter located?
Scientists used data from the European Space Agency's Planck satellite to locate the last of the missing ordinary matter in filaments of hot gas that connect galaxies together in a cosmic web.
4. Why is locating all of the ordinary matter important?
Locating all of the ordinary matter in the universe is important because it helps us understand how galaxies form and evolve over time, and confirms our current understanding of cosmology.
5. What other mysteries are scientists currently exploring in the universe?
Scientists are currently exploring a wide range of mysteries in the universe, including dark matter, dark energy, black holes, and gravitational waves.
