Which concept in cosmology describes the idea that the expansion of the universe is accelerating?

  1. The Big Crunch

  2. The Big Bounce

  3. The Steady State Theory

  4. The Accelerating Universe


Correct Option: D
Explanation:

The Accelerating Universe concept suggests that the expansion of the universe is not constant but is accelerating.

What is the name of the hypothetical particle that is believed to be responsible for dark energy?

  1. The Higgs Boson

  2. The Graviton

  3. The Axion

  4. The Quintessence


Correct Option: D
