Thanks for asking us a question in Ask the Expert section of TopperLearning.com.

 

In case of multiple questions within a query, please post each question individually and let us know where you are getting stuck so that we would be able to explain things better.

 

However answer to your first query asked is,

 

Dark matter is a hypothetical kind of matter that cannot be seen with telescopes but it would account for most of the matter present in the universe. Scientists have not yet observed dark matter directly. It is completely invisible to light and other forms of electromagnetic radiation.

But it exists because of the gravitational effects it appears to have on galaxies and galaxy clusters.

According to the theory, the total mass–energy of the known universe contains 4.9% ordinary matter, 26.8% dark matter and 68.3% dark energy.
