What is TRUE about the Big Bang theory?

• Most widely accepted explanation to the origin of the universe and elements.

• Heavier elements are created during this expansion.

• It is the belief on how planets are being created.

• Explains how different galaxies are interconnected from one another

In 1910, Vesto Slipher and Carl Wilhelm Wirtz observed a phenomenon called redshift. How does redshift occur?

• Distant galaxies move away from the Earth.

• Distant galaxies are moving close to the Earth.

• Distant galaxies remain its position in relation to Earth.

• Distant galaxies are getting bigger than the galaxy where Earth located.

How does the Holmdel horn antenna serve as evidence for the Big Bang Theory?

• It gives a clear picture of how universe expands over time.

• It detects the remaining nuclear particles present on the universe.

• It shows how the elements and compound combines as universe expands

• It detects the existence of cosmic microwave background radiation which are believed as the energy remains from expansion of the universe.
