Cosmological Amnesia

The video discusses the concept of dark energy and the cosmological constant, a term introduced by Einstein to maintain a static universe. Initially dismissed as a mistake, the cosmological constant gained significance with the discovery of the universe's accelerating expansion. The video explores the historical context, the irony of Einstein's actions, and the constant's lasting impact on cosmology.

What is the cosmological constant primarily associated with?

• The static nature of the universe

• The acceleration of the universe's expansion

• The density of dark matter

• The temperature of cosmic microwave background

What was the scientific community's initial reaction to the cosmological constant?

• They immediately accepted it as a fact

• They were unsure of its value and debated its existence

• They believed it was related to black holes

• They rejected it outright

What discovery led to a Nobel Prize related to the cosmological constant?

• The existence of dark matter

• The accelerating expansion of the universe

• The static nature of the universe

• The Big Bang theory

Why did Einstein introduce the cosmological constant initially?

• To describe black holes

• To account for dark matter

• To maintain a static universe model

• To explain the accelerating universe

What did Einstein later refer to the cosmological constant as?

• His greatest achievement

• A minor error

• An unsolved mystery

• His greatest mistake
