Big Bang Theory Pre-Assessment

Front

What are the three main pieces of evidence for the Big Bang Theory?

Back

Redshift, Cosmic Microwave Background (CMB), distribution of elements.

Front

What was contained in the singularity that gave rise to the Big Bang?

Back

All the mass, energy, time, and space in our universe.

Front

What is the term for the band of colors produced when light from a star or galaxy is separated?

Back

Spectrum.

Front

According to the current theory, what existed before the Big Bang?

Back

Nothing.

Front

How old do scientists estimate the Universe to be?

Back

13.8 billion years old.

Front

What is redshift?

Back

The phenomenon where light from an object moving away from us is shifted to longer wavelengths, indicating that the object is receding.

Front

What is the Cosmic Microwave Background (CMB)?

Back

The afterglow radiation from the Big Bang, filling the universe and providing evidence for the Big Bang Theory.

Front

What does the distribution of elements in the universe support?

Back

It supports the Big Bang Theory, as it shows the predicted ratios of hydrogen, helium, and other elements formed in the early universe.

Front

What is the significance of the Doppler effect in astronomy?

Back

It helps determine whether an object in space is moving towards or away from us based on the change in frequency of its light.

Front

What does the term 'singularity' refer to in the context of the Big Bang?

Back

A point in the universe where density and gravity are thought to be infinite, and the laws of physics as we know them break down.
