EzraCatastrophic theory of the solar system suggests that major disruptions or events in the past, such as collisions or close encounters with other celestial bodies, played a significant role in shaping the current structure of our solar system. This theory contrasts with the gradual, slow processes of traditional solar system formation theories.

What is the 'extrinsic catastrophist' theory of comets?
The extrinsic catastrophist theory of comets suggests that comets originate from outside the solar system and are responsible for catastrophic events on Earth, such as mass extinctions. This theory proposes that comets carry organic materials that may have influenced the development of life on Earth.
What is another name for the Nebula Theory?
The Nebula Theory is also known as the Solar Nebula Theory. It is a widely accepted model for the formation of our solar system.
Who on his deathbed in 1543 published his theory that the sun is a motionless body at the centre of the solar system?
Nicolaus Copernicus published his theory that the sun is a motionless body at the center of the solar system on his deathbed in 1543. This theory is known as the heliocentric model, which places the sun at the center of the solar system with the planets orbiting around it.
What is a sentence for heliocentric theory?
The heliocentric theory, proposed by Copernicus, states that the Sun is at the center of the solar system and that the planets, including Earth, orbit around it.
What is the key ingredient in the modern condensation theory of the solar system's origin that was missing or unknown in the nebula theory?
The key ingredient in the modern condensation theory that was missing in the nebula theory is the understanding of the role of turbulence. Condensation theory incorporates the effects of turbulence in the early solar system, showing how it can facilitate the collapse of material into the Sun and the formation of planetesimals. This provides a more detailed and realistic explanation for the formation of the solar system compared to the original nebula theory.
