The Expansion of the Universe Takes Place

question 24

Multiple Choice

The expansion of the universe takes place

• B) only between objects separated by a vacuum; as a result, the bodies do not expand, but the Earth-Moon system does.
• C) between all objects, even between the atoms in the bodies, although the expansion of a person is too small to be measured reliably.
• D) primarily in the huge voids between clusters of galaxies. "Small" objects like galaxies or Earth do not expand.
