How does dark matter interact with normal matter?

Back

Dark matter interacts with normal matter primarily through gravity, but it does not interact with electromagnetic forces, which is why it cannot be seen directly.

Front

What is a singularity in the context of the Big Bang?

Back

A singularity refers to a point in space where density and gravity become infinite, and it is theorized that the universe began from such a point.

Front

What evidence supports the Big Bang Theory?

Back

Evidence supporting the Big Bang Theory includes the cosmic microwave background radiation, the abundance of light elements, and the redshift of distant galaxies.

Front

What is the role of gravity in the formation of galaxies?

Back

Gravity pulls together gas and dust in space, leading to the formation of stars and galaxies over time.

Front

What is the observable universe?

Back

The observable universe is the part of the universe that we can see and measure, limited by the speed of light and the age of the universe.
