Answer 2

Heyy dear♥️

We know only 4 percent of the universe. The other 96 percent is made of stuff astronomers can't see, detect or even comprehend. These mysterious substances are called dark energy and dark matter.

NASA's reports say universe was found to be expanding 5% faster rate than the prediction of 67 kilometers per second per megaparsec.
