What radiation indicates that the universe was once extremely hot and nearly uniformly dense?
The radiation that indicates the universe was once extremely hot and nearly uniformly dense is known as the Cosmic Microwave Background (CMB) radiation. This relic radiation is a remnant from the early universe, specifically from about 380,000 years after the Big Bang, when the universe cooled enough for protons and electrons to combine and form neutral hydrogen atoms. As the universe expanded, this radiation stretched and cooled, now detectable as a uniform glow across the sky, providing crucial evidence for the Big Bang theory and the early conditions of the universe.
Which theory of the universe did the 1964 discovery of cosmic microwave background radiation support?
The 1964 discovery of cosmic microwave background radiation supported the Big Bang theory of the universe. This radiation is considered a remnant of the early stages of the universe when it was hot and dense, aligning with the predictions of the Big Bang model.
How cosmic microwave background radiation shows us the universe is changing?
It shows that at the beginning of time all radiation was trapped in a small place and since the universe has expanded and cooled so has the radiation which is why it has dropped from very high radiation to its fairly low microwave radiation state. Today. It is the afterglow of the universe which heavily backs up the big bang theory.
What does the uniformity of cosmic radiation imply about its source?
The uniformity of cosmic radiation suggests that it originates from sources that are distributed evenly throughout the universe. This could point to sources such as distant galaxies, black holes, or other cosmic phenomena that emit radiation in all directions with similar intensity.
Why was the COBE important to the big bang theory?
NASA's COBE (Cosmic Bakground Explorer) satellite was developed to measure the cosmic microwave background radiation from the early Universe to the limits set by our astrophysical environment. The cosmic microwave background radiation is a remnant of the Big Bang. Study of minute temperature variations are linked to slight density variations in the early universe. These variations are believed to have given rise to the structures that populate the universe today: clusters of galaxies, as well as vast, empty regions.
The heat left over from the beginning of the universe?
The heat left over from the beginning of the universe is known as the cosmic microwave background radiation. It is a faint glow of radiation that permeates the entire universe and is a remnant of the Big Bang. This radiation provides important clues about the early universe and the formation of galaxies.
A sample constructed to represent the major characteristics of the universe?
One possible sample constructed to represent the major characteristics of the universe is the cosmic microwave background radiation. This radiation is a remnant of the Big Bang and provides clues about the early universe's temperature and density. By studying this radiation, scientists can gain insights into the universe's origins, evolution, and composition.
Background radiation detected in space is believed to be evidence that?
the universe underwent a Big Bang, as this radiation is the remnant heat left over from the early stages of the universe. This background radiation, known as the cosmic microwave background, supports the Big Bang theory as it provides a way to study the conditions in the early universe.

What is one major piece of evidence that supports the validity of the Big Bang theory?
One major piece of evidence supporting the validity of the Big Bang theory is the cosmic microwave background radiation, which is a faint glow of radiation that fills the universe and is considered a remnant of the early stages of the universe's expansion.
From the cosmic background radiation scientists can infer that just after the big bang the universe must have been?
hot and dense. The cosmic background radiation provides evidence that in the early universe, all matter and energy were packed closely together and the temperatures were extremely high. This radiation is a remnant from the early stages of the universe's expansion and gives insight into its origins.

Today. It is the afterglow of the universe which heavily backs up the big bang theory.
What is the lowest temperature observed in universe?
The lowest temperature ever observed in the universe is around 2.7 Kelvin (-270.45 degrees Celsius), known as the temperature of the cosmic microwave background radiation, which is a remnant from the Big Bang. It represents the average temperature of space.
What was arno penzias's scientist contribution to understanding the universe?
Arno Penzias, along with Robert Wilson, discovered the cosmic microwave background radiation, which provided strong evidence for the Big Bang theory. This radiation is a remnant from the early stages of the universe and has been essential in shaping our understanding of the universe's origin and evolution. Penzias and Wilson's discovery was awarded the Nobel Prize in Physics in 1978.
