The slower growth of gravitational wells and the accelerating expansion might share the same underlying cause.” In so many ...

That is the provocative assertion behind Professor Ginestra Bianconi’s latest work, which reframes gravity as an emergent phenomenon arising from the interplay of spacetime geometry, quantum ...

Seen as a long strand with smaller threads branching, the Quipu superstructure contains 68 galaxy clusters spanning 1.4 ...

Scientists have come a step closer to understanding how collisionless shock waves—found throughout the universe—are able to accelerate particles to extreme speeds.

You could swim through the deepest voids and encounter a single hydrogen atom in an entire football field's worth of space.

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion.

But just like you'd need a lot of buoys to measure, like, the whole sea, it seems that we need, like, a lot of supernovae to be able to prove anything about, like, cosmic acceleration. NORD: Yeah.

The discovery of the cosmic acceleration problem truly inspired me as a teenage physics nerd. Recent, related revelations about dark energy will hopefully capture the interest of today’s young ...

When modeled this way, space-time naturally gives rise to cosmic acceleration, and what could be crucial evidence of string theory is the data that suggests the acceleration decreases over time ...

I’ve worked on the question of cosmic acceleration for 25 years, and my perspective is, if the evidence continues to grow, and it is likely to, then this will be huge for cosmology and all of ...

These latest results are based on analysis of a full year's worth of data taken from seven different slices of cosmic time and include 450,000 quasars, the largest ever collected, with a record ...
