What is the full form of SCM? 

The correct answer is Standard Cosmological Model

Key Points

• The Standard Cosmological Model, also known as the Lambda-CDM model, is the standard model scientists use to understand the evolution of the universe.
• It proposes that the universe is composed of roughly 70% dark energy, 25% dark matter, and 5% ordinary matter.
• Dark energy, quantified by the cosmological constant Λ (Lambda) is responsible for the accelerating expansion of the universe, while dark matter and ordinary matter contribute to its structure.
• The model describes a universe that began with the Big Bang around 13.8 billion years ago.
• Since then, the universe has been expanding and cooling, leading to the formation of galaxies, stars, and planets.
• The model predicts the Cosmic Microwave Background radiation — the afterglow of the Big Bang — and its observed properties quite well.
• The evolution of large scale structures (clusters and superclusters of galaxies) from small early density fluctuations is also well accounted for in this model.
