The Big Bang Theory is a widely accepted explanation for the origin and evolution of the universe. This cosmological model posits that the universe began approximately 13.8 billion years ago from an extremely hot and dense singularity. From this initial point, the universe has been expanding and cooling, leading to the formation of matter, galaxies, and the large-scale structures we observe today.

The cosmic microwave background (CMB) is a crucial element in the field of cosmology, often referred to as the “afterglow of the Big Bang”. This faint microwave radiation fills the entire universe and provides a snapshot of the early cosmos, about 380,000 years after the Big Bang.
The universe is a vast expanse filled with wonders that continue to baffle and intrigue scientists. One of the most profound mysteries is dark matter, an elusive substance that is believed to make up about 27% of the universe. Unlike ordinary matter, dark matter does not emit, absorb, or reflect light, making it invisible and detectable only through its gravitational effects.
Deep space holds mysteries that have puzzled astronomers and space enthusiasts for centuries. From black holes to distant galaxies, each discovery offers a glimpse into the complex tapestry of our universe.
