In recent years, one of the most troubling puzzles in astrophysics has grown more urgent. Scientists have realized that the ...

What's more, the team used cosmic rays to locate the void and estimate its size through millions of tons of rock. The cavernous space is roughly 100 feet long and sits almost directly above the ...

Time moves slower in stronger gravitational fields, like Earth’s, creating the illusion of faster cosmic expansion in voids between galaxies. Researchers analyzed light from Type Ia supernovae ...

Some estimates suggest that within about a billion light-years, the matter density could be as much as 50% below the cosmic average. If our galaxy lies inside such a void, that could explain why ...
