DB Nebular Theory

Front

What is the DB Nebular Theory?

Back

The DB Nebular Theory explains the formation of the solar system from a rotating cloud of gas and dust, known as a nebula, which collapsed under its own gravity.

What happens to a stellar nebula as it collapses?

Back

As a stellar nebula collapses, it begins to rotate due to the conservation of angular momentum.

Front

How long ago did the solar system begin to form?

Back

The solar system began to form approximately 5 billion years ago.

Front

What are the outer planets of the solar system?

Back

The outer planets are Jupiter, Saturn, Uranus, and Neptune.

Front

What is the general state of the universe?

Back

The universe is generally expanding.

Front

How do stars form according to the DB Nebular Theory?

Back

Stars form when a nebula collapses and nuclear fusion occurs in the core of the forming star.

Front

What is a nebula?

Back

A nebula is a giant cloud of gas and dust in space, often the birthplace of stars.

Front

What role does gravity play in the formation of stars?

Back

Gravity causes the gas and dust in a nebula to collapse and clump together, leading to the formation of stars.

Front

What is nuclear fusion?

Back

Nuclear fusion is the process by which two light atomic nuclei combine to form a heavier nucleus, releasing energy, and is the process that powers stars.

Front

What is the difference between inner and outer planets?

Back

Inner planets (Mercury, Venus, Earth, Mars) are rocky and smaller, while outer planets (Jupiter, Saturn, Uranus, Neptune) are gas giants and larger.
