It can be believed that Mather, Smut and others discovered that the form and anisotropy of bold of the microwave radiation in the cosmic background is crucial to studying the details of the evolution of the universe, and further determined the evolutionary form of the universe born in the Big Bang and the future evolutionary form of the universe. This should be the great significance of in 2006.

The Nobel Prize in Physics in 2006 was awarded to American scientists Mather and Smut. They made new breakthroughs in the research direction of cosmic microwave background radiation, and determined the bold form and anisotropy of radiation.
Picture interpretation: This is the cosmic microwave background radiation pattern. The subtle quantum fluctuations and falls ultimately laid the foundation for subsequent galaxies formation and distribution
Picture interpretation: NASA COBE satellite also measured the accurate background radiation value
The so-called microwave background radiation is the thermal radiation left over from the Big Bang, which fills the entire universe and can be understood as the oldest "light" in the universe. Then, through these lights, we can discover the mysteries of the universe in the early days of the Big Bang.
After years of observation by scientists, it has been determined that microwave background radiation is the first beam of light in the universe, and the spectrum conforms to the characteristics of bold radiation, and the corresponding universe age is about 380,000 years. There were no objects in the universe at that time, no galaxies, let alone intelligent species. These radiations have been remaining in the universe. As the universe expands at an accelerated rate, the radiation wavelength also occurs in redshift to the microwave range. NASA COBE satellites also measured accurate background radiation values, determining the bold radiation spectrum of the cosmic background microwave radiation, which in turn proved that our universe was formed after the Big Bang.
The anisotropy of microwave background radiation also shows that the universe was born in the Big Bang. At the same time, the Wilkinson microwave anisotropy detector in the United States found that microwave background radiation fluctuated in different directions, and the measured age of the universe is 13.7 billion years, which is the age of the universe we currently recognize. At the same time, scientists also confirmed that only 4% of the visible matter in the universe, such as the stars, galaxies, etc., which shows that there are still most things in the universe that we cannot see, including 23% of dark matter , and 73% of dark energy.
Image interpretation: The research findings on the anisotropy and bold form of microwave background radiation further confirm that the universe was born in a big bang
It can be believed that Mather, Smut and others discovered that the bold form and anisotropy of the cosmic background microwave radiation was crucial to studying the details of the evolution of the universe, and further determined the evolutionary form of the universe born in the Big Bang and the future evolution of the universe. This should be the significance of the 2006 Nobel Prize in Physics. For humans, the universe will continue to expand. Since there is no sign of ending the universe, civilizations such as humans can theoretically exist forever in the universe.
