Meanwhile, we refer to the enigmatic force behind the universe’s fast expansion as “dark energy.

One of the biggest problems facing contemporary astronomers is figuring out what these substances are and how they work.

These kinds of surveys are crucial because dark matter models anticipate far more dwarf galaxies than we actually find.
