The Cosmic Microwave Background (CMB) is like a time capsule from the early universe.
It was created about 380,000 years after the Big Bang.
Think of it as the leftover glow from that huge explosion.
It helps us understand what the universe looked like before stars and galaxies formed.
Here are some interesting facts about the CMB:
Uniformity and Fluctuations: The CMB looks pretty much the same everywhere, but it has tiny changes, or fluctuations. These little changes are important because they helped create everything we see today.
Temperature: The CMB has a temperature of about 2.7 Kelvin. This means it has cooled down a lot since the beginning because the universe is always getting bigger.
Evidence for the Big Bang: When scientists found the CMB in 1965, it was big proof that the Big Bang really happened. It showed us that the early universe was very hot and packed together.
In short, studying the CMB lets us look back in time.
It helps us learn about the history and growth of our universe!
