In summary, the Cosmic Microwave Background (CMB) is a faint glow of microwave radiation that is a remnant of the Big Bang and can be observed in all directions in the sky. It provides valuable information about the early universe and its composition, structure, and evolution. The pattern of the CMB can be measured using specialized instruments and changes over time due to the expansion of the universe and the effects of gravity. These changes can give insight into the expansion rate of the universe, the distribution of matter and energy, and the existence of dark energy. They can also support the inflationary theory of the universe's early expansion.

Is the pattern of temperature variation of the cosmic microwave background static, or does it vary over time?

It varies with time. First of all, you have a slow increase of the wave length with time. Second, you have the pattern. This will vary in time just like it varies in space in a sense that when typical structural patterns are 10 Megalightyears in size, they will also change on a time scale of 10 million years.

Excellent! Thank you very much.
 

1. What is the CMB?

The Cosmic Microwave Background (CMB) is the remnant radiation from the Big Bang that permeates throughout the entire universe. It is a faint glow of microwave radiation that can be observed in all directions in the sky.

2. Why is the CMB important?

The CMB provides valuable information about the early universe and the conditions that existed shortly after the Big Bang. It helps us understand the composition, structure, and evolution of the universe.

3. How is the pattern of the CMB measured?

The pattern of the CMB is measured using specialized instruments such as telescopes and satellites. These instruments measure the intensity and polarization of the radiation emitted by the CMB.

4. Does the pattern of the CMB change over time?

Yes, the pattern of the CMB does change over time. This is due to the expansion of the universe and the effects of gravity on the radiation. However, these changes are very subtle and can only be detected with highly sensitive instruments.

5. What can the changing pattern of the CMB tell us about the universe?

The changing pattern of the CMB can tell us about the expansion rate of the universe, the distribution of matter and energy, and the existence of dark energy. It can also provide evidence for the inflationary theory of the universe's early expansion.
