The Big Bang Theory and Elements

The Big Bang Model needed to accurately make predictions for it to be considered valid. One prediction based on the model is that the universe should be largely composed of Hydrogen and Helium. This is because of their atomic structure.

So why hydrogen and helium?

Multiple Choice

Hydrogen is the most abundant element in the universe because it is the simplest element. It has...

• 1 Proton, 1 Electron, No Neutrons

• 2 Protons, 2 Electrons, and 2 Neutrons

• 1 Electron, 1 Electron, 1 Neutron

• 2 Electrons, 2 Electrons, No Neutrons

Multiple Choice

What is the ratio of hydrogen to helium?

• 3:1

• 1:3

• 2:4

• 4:2

Multiple Choice

The Big Bang Model accurately predicted the abundance of elements like hydrogen and helium.

• True

• False

Multiple Choice

The abundance of elements is considered a key piece of evidence in supporting The Big Bang Theory.

• True

• False

Multiple Choice

When a star moves away from us, the light it emits in our direction is stretched causing the wavelengths to get longer. This is called

• Blue Shift

• Red Shift

• The Doppler Effect

• Cosmic Background Radiation

Multiple Choice

Red Shift is one of the key pieces of evidence used to support the universe is

• expanding

• contracting

• exploding

• freezing

Hubble's Law

• Hubble discovered the relationship between distance and redshift (velocity moving away from earth)

• He noticed the more a star was redshifted, the further it was away in distance.

• From this relationship, Hubble claimed that the universe must be expanding.

Multiple Choice

Red Shift supports the big bang theory because...

• the stretching of wavelengths toward the red end of the visible spectra suggests that as light moves across the universe it is experiencing expansion.

• the contracting of wavelengths toward the red end of the visible spectra suggests that as light moves across the universe it is experiencing contraction.

Multiple Choice

What is cosmic microwave background radiation?

• leftover light from the big bang

• electromagnetic spectrum

• gravity

• matter

Multiple Choice

Cosmic Background Radiation is original light from the big bang that has been expanded beyond the visible spectrum to microwaves. These microwaves can be found everywhere in the universe.

• True

• False

Multiple Choice

The shadows in the Cosmic Background Radiation can give scientists an idea where there are...

• giant clumps of matter in the universe (galaxies)

• black holes

• energy rich spaces

• potential other singularities

Multiple Select

Cosmic background radiation is a key piece of evidence supporting the big bang because...

• scientists were able to use what they understood about red shift to make predictions with the model

• scientists found what they predicted would happen

• Scientists are infatuated with it because it makes a really cool map

• scientists are able to use it now to further inform that the universe may have looked like in the past
