Which two scientists proposed the nebular hypothesis?

Question

BlackTom AI · Accepted Answer

The question asks which two scientists proposed the nebular hypothesis.
In this case, the historically accepted duo is Immanuel Kant and Pierre-Simon Laplace.

First, Kant proposed the nebular hypothesis in 1755–1766, suggesting that the Solar System formed from a rotating cloud (a nebula) that contracted and flattened into a disk, with orbits forming planets.

Next, Laplace, building on Kant’s idea, refined the model in the late 18th century (notably in 1796) by incorporating mathematical details of the rotating nebula and the angular momentum distribution, thus strengthening and popularizing the theory.

Since the provided options are not listed, the correct attribution remains Kant and Laplace, who are traditionally credited with proposing and developing the nebular hypothesis. If any other names appear as options, they are not part of the primary historical attribution for this hypothesis.

Note: This explanation focuses on the historical development and the key figures associated with the nebular hypothesis; broader discussions include later refinements and alternative theories, but Kant and Laplace are the classic pair tied to its origin and enhancement.
