The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests that the Solar System formed from nebulous material.
In astronomy, a hypothesis is a proposed explanation for a phenomenon that can be tested through observation or experimentation. It is a tentative idea or prediction that can be supported or refuted based on evidence. Hypotheses in astronomy often lead to the development of theories that help explain the behavior of celestial objects and phenomena.
Both the nebular hypothesis and the protoplanet hypothesis describe the formation of the solar system from a rotating cloud of gas and dust. The nebular hypothesis suggests that this cloud, or nebula, collapsed under its own gravity to form the Sun and planets, while the protoplanet hypothesis specifically focuses on how solid materials within the nebula coalesced to form planetesimals and eventually protoplanets. Both theories emphasize the role of gravitational forces and accretion processes in the development of celestial bodies. Ultimately, they aim to explain the origin and structure of the solar system.
The hypothesis of continental drift was proposed by Alfred Wegener in 1912 to explain the jigsaw-like fit of continents, similarities in rock types and fossils, and paleoclimate data. It wasn't widely accepted until the 1960s when evidence from paleomagnetism and seafloor spreading supported the theory.
One key piece of evidence that was not initially used in support of the continental drift hypothesis was a mechanism explaining how continents could move. It wasn't until the discovery of plate tectonics and the development of the theory of seafloor spreading that a mechanism was found to explain how continents drift.
I think you mean "protoplanet hypothesis". In fact, astronomers usually call it the Nebular Hypothesis A protoplanet is a planet-like object that hasn't fully developed into a planet. Why that hypothesis? It's because it is the best we have to describe the origin of the solar system according to the Laws of Physics.
Hypothesis? Hypothesis is a proposal intended to explain certain facts or observations
When you are using the scientific method, you would try to imagine a hypothesis which explains an observation, but you might not succeed. A hypothesis that does not explain an observation would be considered a failed hypothesis. You would then need to invent a different hypothesis.
so you have to put in did it help you explain your hypothesis
give the compound nucleus hypothesis
A hypothesis is a theory that attempts to explain a certain phenomenon.
to explain why the data support or reject the hypothesis
Then explain why it was wrong
A hypothesis is a suggestion of a way to explain something. If the hypothesis is tested and confirmed, it can advance to the status of theory. The conclusion of testing a hypothesis will be either that the hypothesis is confirmed, or it is not confirmed.
The null hypothesis is an hypothesis about some population parameter. The goal of hypothesis testing is to check the viability of the null hypothesis in the light of experimental data. Based on the data, the null hypothesis either will or will not be rejected as a viable possibility.
