Our best model of the cosmos has a glaring mathematical problem, but we may have found an answer.

A team of scientists says it's possible to use tiny ripples in space and time, or gravitational waves, to measure the rate at which our universe is expanding. This could solve one of the biggest ...

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 ...

Mathematicians are challenging the idea that dark energy is responsible for the accelerating expansion of the universe. In a new paper published in Proceedings of the Royal Society A, mathematicians ...

Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their results match “local” measurements but clash with early-universe estimates, ...

Scientists are hunting for "unknown unknowns" that could lead us to missing ingredients in our recipe of the cosmos. When you purchase through links on our site, we may earn an affiliate commission.

LIGO–Virgo–KAGRA, an international scientific collaboration, has announced a near doubling of the detected ripples in ...

Anyone who has been paying attention to cosmology over the past few years is aware of problems with our best attempts to ...

Once dismissed as empty expanses between galaxies, cosmic voids are becoming one of the most promising tools for probing the ...

Since humanity's earliest days, people have looked up at the stars, using science, art, religion, philosophy, mathematics, and any other tool at their disposal to better understand the complicated and ...

The most precise measurement yet of how fast the Universe is expanding shows we have a real and serious problem on our hands.
