The most precise measurement of the expansion rate ever made suggests an unknown force may be affecting the universe.

A comprehensive new study combines decades of research to reveal that we're missing an essential component in our understanding of how the universe works.

An expanding universe complicates this picture just a little bit, because the universe absolutely refuses to be straightforward. Objects are still emitting light, and that light takes time to travel ...

The Big Bang theory has dominated our understanding of the universe’s origin for almost 100 years. It describes a moment when all of space, time, and energy were born from a single infinitely dense ...

Cosmologists have long treated black holes and the Big Bang as separate extremes of physics, one swallowing light, the other birthing space and time. A provocative line of research now suggests those ...

Astrophysicists have presumed for nearly a century that the universe will just keep expanding for all eternity, driven by an invisible force called dark energy. But new data suggest that this is ...

The universe is stretching apart faster than our current theories of physics can explain, and a new study has just confirmed that the discrepancy is not a fluke. By funneling decades of data into the ...

The surface of Earth is finite. We can measure it. If it was expanding, then its size would grow with time. And once again, good ol' Earth helps us understand what the universe might be doing beyond ...
