Overview of the Big Bang Theory, its origins, and supporting evidence. Learn about the theory proposed by George Le Maitre, how the universe expanded from a singularity, and the key evidence such as red shift and cosmic background microwave radiation that supports this groundbreaking concept.
The idea of the Big Bang Theory was first proposed by George Le Maitre in the 1920s and was later developed by many scientists, including Gamenov in the 1970s.
According to this theory:
Everything in the universe emerged from a single point known as the Singularity approximately 15 billion years ago.
The universe began expanding from a state of very high density and temperature.
A major cosmic explosion occurred 13-15 billion years ago, which expelled all the matter of the universe.
This matter eventually accreted to form stars, solar systems, and other celestial bodies.
Evidence in Support:
Red Shift: As an object (or light) moves away from us, its wavelength increases and shifts to the red end of the spectrum, known as Red Shift.
CBMR (Cosmic Background Microwave Radiation): Electromagnetic radiation present shortly after the Big Bang is now observed as background microwave radiation.
