FAQs (Frequently Asked Questions)
What is the Big Bang theory and its relationship to the universe?
The Big Bang theory proposes that the universe began as a singularity and expanded rapidly from an immensely hot and dense state about 13.8 billion years ago. This expansion led to the formation of galaxies, stars, and the cosmos as we know it today.
What is dark matter, and how does it relate to the universe?
Dark matter is a mysterious form of matter that does not emit or interact with light, making it invisible to our telescopes. It exerts gravitational forces on visible matter, galaxies, and galaxy clusters, contributing to the structure and dynamics of the universe.
Are there other universes beyond our own?
The existence of other universes, often referred to as a “multiverse,” is a theoretical concept in cosmology and physics. Some theories, such as the “Many-Worlds Interpretation” of quantum mechanics, suggest the possibility of parallel universes or alternate realities.
How old is the universe?
Based on current scientific understanding, the age of the universe is estimated to be approximately 13.8 billion years. This age is calculated through observations of the cosmic microwave background radiation and the expansion of the universe.
