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

For decades, string theory has promised to be the ultimate explanation for how our universe works. In this theory, all matter ...

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 ...

What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

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.

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

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

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 ...

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 ...

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 ...

The acceleration was clear in the data, and confirmed by multiple groups, but it didn’t seem to make any sense. Researchers expected expansion to de celerate, not accelerate.
