THE ORIGIN OF UNIVERSE

The Big Bang Theory:  Big bang is the origin of universe.  The Big Bang theory is the most widely accepted scientific explanation for the origin of the universe. It is a theory that describes the early universe as an incredibly hot, dense, and expanding state that originated from a single point, known as a singularity. This theory has been refined and tested over many decades, and it is supported by a vast amount of observational evidence.  The big bang The Origin of the Big Bang Theory: The big bang theory was proposed by George LemaĆ®tre. He was also known as father of big bang theory. The origin of the Big Bang theory can be detected back to the early 20th century when astronomers observed that distant galaxies were moving away from us. This observation led to the realization that the universe was expanding. The discovery of the cosmic microwave background radiation in the 1960s provided further evidence for the Big Bang theory. This radiation is the remnant of the early universe, an

DARK ENERGY and DARK MATTER

Dark matter and dark energy are two of the most mysterious and intriguing topics in modern physics. Despite their apparent invisibility and elusiveness, scientists believe that they make up the vast majority of the universe.  Dark Energy and Dark Matter DARK MATTER:  Dark matter is a type of matter that cannot be detected through electromagnetic radiation because it does not interact with light or any other form of electromagnetic radiation. It is believed to be present in the universe because of the gravitational effect it has on visible matter. In other words, visible matter seems to be affected by a gravitational force that is much stronger than can be accounted for by the visible matter alone.  Dark Matter This suggests that there must be some invisible matter that is exerting the additional gravitational pull. The existence of dark matter was first proposed in the 1930s, but it was not until the 1970s that its existence was widely accepted.   Scientists believe that dark matter ma
