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 is a hypothesis in astronomy?
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.
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.
How does observing patterns in the world help scientists answer scientific questions?
Patterns offer clues as to what is going on. The clues lead scientists to make a hypothesis, a tentative explanation that accounts for the observed pattern. The hypothesis then gets tested, sometimes in ingenious ways. If the hypothesis holds up, you may have a working theory on your hands. The theory would be the best current explanation for the pattern. If you can explain the pattern, you have the answer to a scientific question. If the theory is good, it will lead to other possibilities that have not yet been observed. And if the theory is excellent, these unobserved possibilities will eventually be detected. These new observations will be considered strong evidence in support of the theory's soundness.
What is the name of a scientific guess?
A hypothesis is a tentative explanation of facts or phenomena. A conjecture is similar to a hypothesis but is an opinion based on speculation or incomplete evidence.
Why did other scientist not believe Alfred Wegener hypothesis?
Other scientists did not believe Alfred Wegener's hypothesis of continental drift in the early 20th century because he did not provide a plausible mechanism for how continents could move through the oceanic crust. Additionally, Wegener's evidence supporting his idea was largely based on geological and fossil similarities between continents, which were not considered strong enough to support such a revolutionary idea at the time. It wasn't until the mid-20th century, with the development of the theory of plate tectonics, that Wegener's hypothesis gained widespread acceptance.
What is a theory based on?
A theory is based on a hypothesis. A hypothesis is an estimated or intelligent guess about the outcome of an experiment. A theory is based on what happens during the experiment.
Hypothesis it is a--------- based on observation and the knoledge of the topic.?
An hypothesis is a theory based on observation and the knowledge of the topic.
A theory or explanation that is based on observations?

A hypothesis.
A possible explanation for a natural event based on observations and past knowledge?
theory
What integrated explanation of numerous hypothesis is known as?
A tentative explanation in research is called a hypothesis. The hypothesis is based on observation. The general explanation of the observation is called a theory. In other words, a theory is the result of testing a hypothesis.
What is the difference between an observation hypothesis and theory?
A hypothesis is an 'educated guess' based on observation and common sense. A theory is a commonly-accepted hypothesis that has held under the pressure of testing by many different scientists.
What is an unproven statement based on observations?
It is a conjecture, or an hypothesis in the scientific method. An hypothesis supported by experiment can become a theory.
Explain the difference between a hypothesis and a theory?
A very complicated question but to pare it down: An hypothesis is a preliminary answer to a scientific question but is one which needs testing. A theory is an hypothesis that has withstood numerous tests and has not failed.
What is the relation between a hypothesis and theory?
A hypothesis is a tentative theory which is unverified, but if true could explain selected facts or observations. A hypothesis expresses an opinion which isn't necessarily based on provable evidence. A theory is a little more solid than a hypothesis, so a hypothesis when tested and proved to have some basis might become a theory. A theory might also refer to a belief with little or no fact behind it at all: he has a theory that the month in which people are born affects their personalities.
What are the differences between hypothesis and theory?
A hypothesis is a proposed explanation for a phenomenon that can be tested through experimentation or observation, whereas a theory is a well-substantiated explanation based on evidence from multiple studies. The main difference is that a theory has been repeatedly tested and confirmed, while a hypothesis is still being investigated.
Can hypothesis be called a theory?
A hypothesis and a theory are distinct concepts in scientific terminology. A hypothesis is a testable prediction or explanation based on limited evidence, while a theory is a well-substantiated explanation of an aspect of the natural world that is supported by a significant body of evidence. While a hypothesis can be a stepping stone to developing a theory, it cannot be called a theory until it has been rigorously tested and widely accepted by the scientific community.
