Life and Its Beginnings

What is the age of the Universe?

Universe started from singularity, then after some time it expands. What theory best describes it?

• Expansion of the Universe theory

• The inflation theory

• Big Bang Theory

• Steady State Theory

Having said that universe came from singularity. What science can't factually answer according to this statement?

• What is singularity?

• How, when, and where the singularity is born?

• Is singularity essential?

• Why singularity is born?

According to a Belgian cosmologist, named Georges Lemaitre, the idea of an expanding universe is called the "hypothesis of the primeval atom" or ?

• cosmic wave

• big bang

• hypothesis of singularity expansion

• none of the choices

Who formulated the "hypothesis of the primeval atom"? What is another term for "hypothesis of the primeval atom"?

• George Lemaitre | cosmic wave

• Georges Lemaitre | the cosmic egg

• George Gamow | the cosmic egg

• George Lemaitre | Cosmic egg

• Georges Lemaitre | cosmic egg

Who is George Gamow?

• He contradicted the idea of cosmic microwave background radiation

• A French cosmologist

• He's nothing to be considered

• He developed and formulated the Big Bang Theory

Explain Cosmic microwave background radiation

• it is a snapshot of the oldest light in our universe that can be detected only by super sensitive technology and believed to be travelling freely around the universe

• Given the measured radiation temperature of 2.735 K, the energy density of the cosmic microwave background can be shown to be about 1,050 times smaller than the average rest-energy density of ordinary matter in the universe. Thus, the current universe is matter-dominated.

• the cooled remnant of the light that can't travel freely throughout the universe that can be detected only by super sensitive technology

• none of the choices

All the matters inside of the singularity should be the same materials being propagated as it expands "infinitely"

• True

• False

What is the significance of the cosmic microwave background radiation in understanding the early universe?

• It provides evidence for the Big Bang Theory

• It contradicts the theory of an expanding universe

• It has no relevance to cosmology

• It is a recent discovery with no historical significance

Which scientist is known for proposing the concept of the expanding universe based on redshift observations?

• Albert Einstein

• Edwin Hubble

• Stephen Hawking

• Isaac Newton
