The extrastellar solar hypothesis suggests that the Sun and other stars may have formed from material ejected from previous supernova explosions or the remnants of older star systems. This theory posits that the solar system's formation was influenced by external cosmic events rather than solely by local interstellar material. Such interactions could provide insights into the chemical composition and evolutionary history of the solar system. Overall, this hypothesis highlights the interconnectedness of stellar evolution and the origins of planetary systems.
The hypothesis of solar energy states that solar energy will be one of the leading sources of energy in the world in the years to come.
The hypothesis on how the solar system was formed is known as the solar nebula theory. This theory posits that the solar system formed from a massive, rotating cloud of gas and dust called the solar nebula. Over time, gravity caused the material in the nebula to clump together, eventually forming the sun and the planets.
The Solar Nebula Hypothesis was developed independently by Soviet astrophysicist Victor Safronov and American astrophysicist Carl Woese in the 1960s. They proposed that the solar system formed from a swirling cloud of gas and dust called the solar nebula.

The presence of protoplanetary disks around other stars, known as proplyds, supports the solar nebula hypothesis. These disks resemble the early solar system's disk of gas and dust that eventually formed the planets. Additionally, the discovery of exoplanets in various stages of formation further reinforces the solar nebula hypothesis.

The hypothesis for a solar eclipse could be formulated as: "During a solar eclipse, the moon passes between the sun and the Earth, causing the sun to be partially or fully obscured from view on Earth." This hypothesis can be tested by observing and analyzing the alignment and movement of the sun, moon, and Earth during a solar eclipse event.

A solar powered airplane is not an hypothesis. There have been many successful experimental flights. A solar powered plane uses electric motors powered by solar panels (or sometimes batteries charged with solar power). At the present time solar panels are only efficient enough to power very light planes.

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.

It indicates about the Origin of Solar System as per Nebular Hypothesis.
The hypothesis you're referring to is the Nebular Hypothesis. It proposes that the solar system formed from a giant rotating cloud of gas and dust, known as a solar nebula. As this nebula collapsed under its own gravity, it spun faster and flattened into a disk, leading to the formation of the Sun at its center and the planets from the surrounding material. This process explains the structure and composition of the solar system as we observe it today.
The most widely accepted model for the formation of the solar system is the nebular hypothesis. This theory suggests that the solar system formed from a rotating mass of gas and dust known as the solar nebula, which collapsed under its own gravity to form the Sun and surrounding planets approximately 4.6 billion years ago.
The Solar nebula hypothesis is supported by several lines of evidence, including the observation of protoplanetary disks around young stars, which resemble the proposed structure of our early solar system. Additionally, the distribution of angular momentum in the solar system, with the Sun containing most of the mass and planets forming a flat disk, aligns with predictions of the hypothesis. The chemical composition of the planets, which reflects the solar nebula's materials, further corroborates this model. Lastly, computer simulations of the collapse of gas and dust clouds consistently produce outcomes that resemble the formation of our solar system.
