WASHINGTON (Reuters) - New data involving millions of galaxies and luminous galactic cores is providing fresh evidence that the enigmatic and invisible cosmic force called dark energy - responsible ...

“As a result, for the past four decades, most researchers have believed that dark matter must be cold when it is born in the ...

For a generation, cosmologists have treated dark energy as a fixed backdrop, a steady pressure stretching space faster and faster forever. Now a wave of new measurements suggests that this invisible ...

For decades, astronomers have relied on Einstein’s theory of relativity to explain the expansion of the universe, assuming that dark energy—a mysterious force making up 70% of the cosmos—remains ...
