Understanding the Big Bang Theory

The video explains the Big Bang Theory, supported by four main lines of evidence: galaxy movement, element abundance, cosmic microwave background radiation, and galaxy formation. Additional evidence includes dark matter, dark energy, and supernovae observations. The theory is well-supported, akin to gravity and evolution, and continues to be refined with new experiments.

What is the general consensus among astronomers about the Big Bang Theory?

• It is only a minor theory with little evidence.

• It is considered a disproven hypothesis.

• It is widely accepted as the origin of the universe.

• It is a recent theory with no historical basis.

Who first calculated the speed and direction of 'spiral nebulae'?

• Galileo Galilei

• Vesto Slipher

• Isaac Newton

• Albert Einstein

What did Edwin Hubble discover about galaxies?

• They are moving towards us.

• They are outside the Milky Way and moving away.

• They are stationary and do not move.

• They are all within the Milky Way.

What is Big Bang Nucleosynthesis?

• The creation of black holes.

• The fusion of hydrogen into helium in the early universe.

• The process of star formation.

• The cooling of the universe.

What did Arno Penzias and Robert Wilson discover in the 1960s?

• The cosmic microwave background radiation.

• The first exoplanet.

• The first black hole.

• The expansion of the universe.

What does the cosmic microwave background radiation indicate?

• The universe is cooling down.

• The universe is contracting.

• The universe is static.

• The universe has a hot and dense origin.

What happened about 10,000 years after the Big Bang?

• The universe began to contract.

• The universe became completely dark.

• The universe reached its maximum size.

• The first stars and galaxies formed.

What are the four pillars of the Big Bang Theory?

• Galaxies moving away, Big Bang Nucleosynthesis, cosmic microwave background radiation, and formation of galaxies.

• Galaxies moving away, Big Bang Nucleosynthesis, cosmic microwave background radiation, and the discovery of dark matter.

• Galaxies moving towards us, Big Bang Nucleosynthesis, cosmic microwave background radiation, and formation of galaxies.

• Galaxies moving away, Big Bang Nucleosynthesis, cosmic microwave background radiation, and the creation of black holes.

What additional evidence supports the Big Bang Theory?

• The static nature of the universe.

• The absence of cosmic microwave background radiation.

• The presence of stars older than 13.8 billion years.

• The discovery of dark matter and dark energy.

How should we regard the Big Bang Theory?

• As a mere hypothesis with little evidence.

• As a well-supported theory similar to gravity and evolution.

• As a new and untested idea.

• As a disproven theory.
