What are the two main factors that affect the strength of gravity?

Back

Mass and Distance.

Front

What is a nebula?

Back

A vast cloud of gas and dust in space where stars are formed.

Front

What are the primary components of the universe?

Back

Dust and gases.

Front

What does the Big Bang Theory explain?

Back

How our universe began.

Front

Describe the Big Bang Theory.

Back

The universe started as a hot, dense point in space that is rapidly expanding.

Front

What role do nebulae play in the formation of galaxies?

Back

Nebulae are the regions where stars form, which can lead to the formation of galaxies.

Front

How does distance affect gravitational force?

Back

The greater the distance between two objects, the weaker the gravitational force between them.

Front

What is the significance of mass in relation to gravity?

Back

The greater the mass of an object, the stronger its gravitational pull.

Front

What is the relationship between dust, gas, and star formation?

Back

Dust and gas in nebulae come together under gravity to form stars.

Front

What evidence supports the Big Bang Theory?

Back

Cosmic microwave background radiation and the redshift of distant galaxies.
