Which event from the Bing Bang Theory is about a huge explosion that happened at one point which initiated the existence of the universe?

• Cosmic Inflation

• Cosmic Expansion

• Cooling Down

• Domain Expansion

What is NOT true about the explosion that started the whole universe?

• The event had high temperature

• The event had high density

• The event had high pressure

• The event had high volume

Answer explanation

The explosion had a LOW volume (or space)

Which event from the Big Bang Theory is about the temperature dropping which causes the formation of galaxies, stars and many other celestial bodies?

• Cosmic Inflation

• Continuing Expansion

• Domain Expansion

Answer explanation

How could you get this wrong? I mean, even the sentence said “temperature dropping”
