Big Bang Theory - Practice

What is the Big Bang Theory?

• A theory that says the universe began as a small point that expanded rapidly about 13.7 billion years ago.

• A hypothesis that suggests the universe is static and unchanging.

• A concept that describes the universe as infinite and eternal without a beginning.

• A scientific explanation for the formation of black holes in space.

What is a spectrum in the context of light emitted from stars or galaxies?

• A band of colors that light can be separated into.

• A type of star classification system.

• A measurement of a star's distance from Earth.

• A method to determine a star's temperature.

How does redshift relate to the expansion of the universe?

• Redshift indicates that galaxies are moving away from us, supporting the idea that the universe is expanding.

• Redshift is a phenomenon that only occurs in nearby galaxies.

• Redshift shows that the universe is contracting over time.

• Redshift has no relation to the movement of galaxies.

What does the Big Bang Theory explain?

• How our universe began.

• The formation of black holes.

• The existence of dark matter.

• The theory of evolution.

What are some alternative theories to the Big Bang Theory?

• Steady State Theory and the Oscillating Universe Theory.

• Quantum Fluctuation Theory and the Static Universe Theory.

• Multiverse Theory and the Infinite Universe Theory.

• String Theory and the M-Theory.

What evidence supports the Big Bang Theory?

• The Cosmic Microwave Background Radiation and the observed redshift of distant galaxies.

• The presence of dark matter in the universe.

• The uniform distribution of stars in the night sky.

• The existence of black holes in the universe.

What is the relationship between redshift and distance in astronomy?

• The greater the redshift, the closer the galaxy is to Earth.

• There is no relationship between redshift and distance.

• Generally, the greater the redshift, the farther away the galaxy is from Earth.

• Redshift only applies to nearby galaxies.

What is the significance of the Cosmic Microwave Background Radiation?

• It provides a snapshot of the early universe and supports the Big Bang Theory.

• It is the first light emitted by stars in the universe.

• It is a form of radiation that causes black holes to form.

• It is the remnant radiation from supernova explosions.

What does RED shift of light indicate about a star's movement?

• The star is moving away from Earth.

• The star is moving towards Earth.

• The star is stationary relative to Earth.

• The star is orbiting another star.

What role does gravity play in the evolution of the universe post-Big Bang?

• Gravity causes the universe to expand indefinitely.

• Gravity helps to form structures like galaxies and clusters of galaxies.

• Gravity has no significant effect on the universe's evolution.

• Gravity only affects small celestial bodies, not large structures.
