What does the Big Bang Theory propose about the origin of the universe?

1. Life began from a primordial soup

2. All matter originated from a large explosion

3. The planets were created from gravitational forces

4. Life was created by divine intervention

The correct answer is: All matter originated from a large explosion

The Big Bang Theory proposes that the universe originated from an extremely hot and dense state and expanded rapidly about 13.8 billion years ago. This theory emphasizes that all matter, energy, space, and time were created at that moment of the Big Bang, which can be imagined as a massive explosion that set everything in motion. The concept hinges on empirical evidence, including observations of the cosmic microwave background radiation and the redshift of distant galaxies, which support the idea that the universe is continually expanding from its initial state. Therefore, the statement about all matter originating from this large explosion aligns perfectly with the fundamental principles of the Big Bang Theory. This theory lays the groundwork for understanding the formation of the universe, galaxies, stars, and ultimately planets over billions of years.
