The Big Bang Theory vs. Steady State Theory: Explaining the Evolution and Expansion of the Universe

The video explores two theories explaining the universe's expansion: the Big Bang and Steady State theories. It discusses the red-shift of light as evidence of expansion, with the Big Bang Theory suggesting a hot, dense origin 13.8 billion years ago, supported by cosmic microwave background radiation. The Steady State Theory posits continuous matter creation to maintain density. The Big Bang Theory is more widely accepted due to additional supporting evidence.

What phenomenon is used as evidence for the expansion of the universe?

• Yellow-shift

• Red-shift

• Blue-shift

• Green-shift

According to the Big Bang Theory, how did the universe begin?

• From a vast, empty space

• From a large, cold region

• From a small, dense, and hot region

• From a medium-sized, warm region

What is the main evidence supporting the Big Bang Theory?

• The creation of new matter

• The constant density of the universe

• The presence of dark matter

• Red-shifted light from distant galaxies

What does the Steady State Theory propose about the universe's expansion?

• The universe is contracting

• The universe is shrinking

• New matter is created as the universe expands

• The universe remains static

How does the Steady State Theory explain the red-shift of distant galaxies?

• By denying the existence of red-shift

• By proposing new matter creation

• By indicating galaxies are stationary

• By suggesting galaxies are moving closer

What additional evidence supports the Big Bang Theory?

• The presence of black holes

• The observation of blue-shifted galaxies

• The detection of cosmic microwave background radiation

• The discovery of dark energy

Why is the Big Bang Theory more widely accepted than the Steady State Theory?

• It denies the creation of new matter

• It was proposed first

• It is simpler to understand

• It has more supporting evidence
