The Big Bang theory is not as simple as it sounds. Scientists now believe it was a period of time rather than a specific moment. This theory has been supported by the discovery of the cosmic microwave background (CMB) radiation.
In the 1960s, Bell Labs scientists Penzias and Wilson accidentally stumbled upon the CMB while using a horn antenna in Holmdel, NJ. This discovery provided crucial insights into the origins of spacetime and the universe itself.
The CMB is essentially the “background noise of the universe” that can be detected in all directions of space. It is a remnant of the early stages of the universe, just 380,000 years after the Big Bang. By studying the CMB, scientists can learn more about the conditions of the early universe, such as its temperature and density.
This discovery has opened up a new realm of possibilities for cosmologists to explore the origins of spacetime and the universe. It challenges our traditional understanding of the Big Bang and allows us to delve deeper into the mysteries of the cosmos.
