The protoplanet theory, which explains the formation of planets from a rotating disk of gas and dust surrounding a young star, was developed through the contributions of several scientists. Key figures include the physicist Carl Friedrich von Weizsäcker and later improvements by others such as Steven J. Desch. This theory evolved from earlier models of planetary formation and has been refined through observations and simulations of protoplanetary disks.

What is one of the accepted theories of the formation of the moon?
An early collision by (proto) Earth with a large protoplanet..
What does the protoplanet hypothesis describe the formation of?
The protoplanet hypothesis describes the formation of planets from the dust and gas present in the early solar system. It suggests that small planetesimals collided and merged to form larger celestial bodies, eventually leading to the creation of the planets we see today.
Why did originate the protoplanet hypothesis based on theory?
The protoplanet hypothesis originated from the need to explain the formation of planets in a systematic way, based on observations of protoplanetary disks around young stars. It suggests that dust and gas in these disks coalesce through processes like accretion and gravitational attraction, leading to the formation of larger bodies, or protoplanets. This hypothesis is supported by the laws of physics, including gravity and conservation of angular momentum, and aligns with the observed structure of our solar system and others. Ultimately, it provides a coherent framework for understanding the transition from dust clouds to planetary systems.
What happened to the protoplanet because of the heat?
The protoplanet underwent differentiation, where heat caused materials to separate based on their density. The heavy elements sank to the core, while lighter materials floated to the surface, forming layers. This process is important in planetary formation as it leads to the creation of distinct layers within a planet.
What observation led jean senebier to develop his theory?
Jean Senebier developed his theory of plant respiration after observing that plants consume oxygen and release carbon dioxide during photosynthesis. This led him to propose that plants have a respiratory process that involves the consumption of oxygen.
Why does protoplanet theory remain theory?
In science, the word "theory" is USUALLY used for well-established theoretical frameworks, that are generally accepted as being true. This is the case with the theory on protoplanets - it is generally held to be true.
How did we get the moon where did it come from?
Currently, the most accepted theory is that it resulted from a crash between a large planetoid (or "protoplanet") and Earth.
Who propose this theory?
Karl Marx proposed the theory of communism.
What new theory did Thomas Edison propose?
the 69 theory LOL
When was the theory of relativity first propose?
1905
What are 2 reasons why the scientific method is used?
To propose a Theory and to make a Theory into a Law
When did Aristotle propose his theory about the universe?
when he died :P
Who was the first scientist to propose a theory about how life evolves?
Charles Darwin. His theory is The Theory of Natarual Seletion. A theory that has been proved even today
Did erikson propose the theory of childhood sexuality first?
Yes
Who was the first to propose a theory of evolution documented by evidence?
Darwin .
Theory about the origin of the moon?
There are several, but one of the more popular is that a protoplanet about the size of Mars originally shared Earth's orbit. It crashed into Earth, and threw off a gigantic cloud of debris that coalesced into the Moon. If you'd like to read more about this, look up "Theia", the name given to this hypothetical protoplanet.
Who propose the phlogiston theory?
The phlogiston theory was first proposed by Johann Joachim Becher in 1667. This theory is now considered obsolete and was replaced by the oxygen theory.
