The video explores the mystery of why the universe exists despite the expected annihilation of matter and antimatter after the Big Bang. It explains antimatter's properties, the imbalance between matter and antimatter, and the role of the weak nuclear force. The video discusses the need for theoretical work beyond the Standard Model to solve this mystery, highlighting the importance of future research in understanding the universe's structure.

What is the primary characteristic that distinguishes antimatter from matter?

• Antimatter has a different mass.

• Antimatter is heavier than matter.

• Antimatter has the opposite electric charge.

What process occurs when a particle of matter meets its antimatter counterpart?

• Fusion

• Fission

• Annihilation

• Decay

According to the Big Bang theory, what should have been the initial ratio of matter to antimatter?

• 3:1

• 1:2

• 1:1

• 2:1

What is the process called when a photon turns into a pair of matter and antimatter particles?

• Annihilation

• Pair production
