Big Bang Theory Review

Front

What is Cosmic Microwave Background (CMB) radiation?

Back

CMB radiation is the afterglow of the Big Bang, originally high energy, but cooled down as the universe expanded.

Front

Why is the abundance of Hydrogen (H) and Helium (He) in the universe significant?

Back

H and He were two of the first elements to form after the Big Bang, supporting the theory of cosmic evolution.

Front

How does CMB radiation support the Big Bang Theory?

Back

CMB radiation supports the idea that the universe was once much hotter and has since cooled.

Front

What does the graph representing the relationship between time and the size of the universe look like according to the Big Bang Theory?

Back

The graph shows an exponential increase in size as time progresses, indicating rapid expansion.

Front

Which type of electromagnetic radiation has the longest wavelength?

Back

Radio Waves have the longest wavelength and the lowest frequency/energy.

Front

What are the first two elements formed in the universe?

Back

Hydrogen (H) and Helium (He) were the first two elements formed after the Big Bang.

Front

What does the term 'redshift' refer to in the context of the universe?

Back

Redshift refers to the phenomenon where light from distant galaxies is shifted to longer wavelengths, indicating that the universe is expanding.

Front

What is the significance of the Big Bang Theory in cosmology?

Back

The Big Bang Theory explains the origin of the universe and its subsequent expansion, providing a framework for understanding cosmic evolution.

Front

What evidence supports the Big Bang Theory?

Back

Evidence includes the abundance of light elements, the cosmic microwave background radiation, and the redshift of distant galaxies.

Front

What is the role of supernovae in the context of the Big Bang?

Back

Supernovae contribute to the formation of heavier elements and provide evidence for the processes that occurred after the Big Bang.
