The correct answer is: It verifies that the early universe was once extremely hot.
The cosmic background radiation provides evidence that:
- It supports predictions of the composition of the early universe.
- It proves that the universe is expanding.
- It pinpoints the size of the original universe.
- It verifies that the early universe was once extremely hot.
The correct answer is: It supports predictions of the composition of the early universe.
Cosmic background radiation, also known as the cosmic microwave background (CMB), is a form of electromagnetic radiation that is uniformly spread throughout the universe. It is essentially leftover radiation from the early stages of the universe, when the universe was extremely hot and dense.
The composition of the early universe is a key aspect in understanding its origins. Scientists have predicted that the early universe consisted of a specific combination of different types of matter and energy. The discovery and analysis of the cosmic background radiation has provided strong evidence that supports these predictions.
To get this answer, you can study the concept of cosmic background radiation and its significance in understanding the origins of the universe. You can also refer to scientific research papers or textbooks that discuss the cosmic background radiation and its implications. This will help you understand how the composition of the early universe is inferred from the characteristics of the cosmic background radiation.
