The accretion theory, which explains the formation of celestial bodies like planets through the gradual accumulation of dust and gas, was primarily proposed by scientists in the early 20th century, including the work of the American astronomer and astrophysicist, Carl Friedrich Gauss. However, it gained significant attention and development through the contributions of various researchers, including the German astronomer Hermann von Helmholtz and later by others in the field of astrophysics. The theory has evolved over time with advancements in our understanding of stellar and planetary formation.
The two men who proposed the collision theory are Max Trautx and William Lewis. The theory which was proposed in 1918 explains how chemical reactions occur.

The theory of cosmology that Copernicus proposed is called the heliocentric theory. This theory placed the Sun, rather than the Earth, at the center of the solar system, with the planets orbiting around it.
The theory of biological cells was proposed by Matthias Schleiden and Theodor Schwann in the 1830s. They proposed that all living organisms are composed of cells, which laid the foundation for the cell theory.

Albert Einstein proposed the theory of relativity in the early 20th century. His theory revolutionized our understanding of space, time, and gravity.
