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.
Albert Einstein discovered the Theory of Relativity.
An early collision by (proto) Earth with a large protoplanet..
Albert Einstein discovered that time and space are relative in his theory of relativity, which he published in 1905 and expanded upon in his theory of general relativity in 1915. These theories revolutionized our understanding of the nature of time, space, and gravity.
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.
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.
Currently, the most accepted theory is that it resulted from a crash between a large planetoid (or "protoplanet") and Earth.

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.
Genic balance theory is discovered by american scientist Calvin Blackman Bridges
schwarschild may be the one who has discovered it with a believable theory

Music theory was never "discovered". It has been developed over time from the roots and beginnings hundreds of years ago.
its not really a matter of who "discovered" the instinct theory but who PROPOSED the instinct theory is what i think your question is asking in which case i believe the answer--if my memory serves me right-- is William McDougall
If new observations are discovered that clash with the previous theory, then the theory will have to be revised.
they discovered theory's of atoms
