For almost a century, astronomers have hypothesized that the universe contains more matter than what can be observed by the human eye. It is now believed that approximately 80 percent of the universe's mass is made up of ...
Physicists use two types of measurements to calculate the expansion rate of the universe, but their results do not coincide, which may make it necessary to update the cosmological model. "It's like trying to thread a cosmic ...
