Which of the following is evidence for the existence of "dark matter" in the universe? The rate of expansion of the universe is speeding up. Stars eventually use up their fuel and stop shining. The outlying stars in a galaxy appear to rotate more rapidly than expected. The background temperature of the universe is 3K/

dark matters are considered as substances that do not absorb or reflect light , and cannot directly be seen, but interacts through gravity with matters that can be seen.

It has been discovered that their existence is based on their effect on visible objects.

In this case, the outer parts of galaxies rotate about their centers at unexpected velocities. These velocities indicate that there are massive halos around each galaxy made of matter invisible to astronomers.

Considering the available options, the statement of the evidence for the existence of "dark matter" in the universe is "the outlying stars in a galaxy appear to rotate more rapidly than expected."

What is Dark Matter?

Dark Matter is the central part of the Universe that is believed to make up about 85 percent of the universe.

Due to the dark matter nature, it has been observed that the distant stars in a galaxy appear to rotate more rapidly than expected.

Other evidence for the existence of dark matter include the following:

The motions of stars in galaxies
The orbits of galaxies in galaxy clusters
The temperature of the gas in galaxy clusters

Hence, in this case, it is concluded that the correct answer is option C. "The outlying stars in a galaxy appear to rotate more rapidly than expected."
