The Vera C. Rubin Observatory, which houses a telescope with the largest digital camera ever built, has revealed its first ...

“If this result stands, this is the most important finding about dark energy since the discovery of cosmic acceleration in 1998,” said astrophysicist Mustapha Ishak, a professor at the ...

The scientists who discovered this apparent acceleration, Saul Perlmutter, Brian Schmidt, and Adam Riess, were awarded the ...

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.

Brian Schmidt explains dark energy’s role in accelerating universe expansion, 1998 discovery’s impact, and urges students to ...

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.

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 ...

If it persists, such a result will shed some light on what is causing cosmic acceleration and provide a huge step in understanding the evolution of our universe." ...

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 ...

If the vacuum does not gravitate at all, what is causing the cosmic acceleration? We don’t know what dark energy is, but we need to assume it exists in order to explain the universe’s expansion.
