Physicists have recreated the mechanism behind cosmic ray acceleration in a lab for the first time using ultracold atoms and ...

Scientists have used ultracold atoms to successfully demonstrate a novel method of particle acceleration that could unlock a ...

This progress means that, for the first time, complicated astrophysical events like shocks and turbulence can be studied in a ...

Rather than requiring mysterious dark energy, observed acceleration might result from how we measure cosmic distances and time across vastly different regions of space.

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

Evidence is mounting that cosmic dark energy, long thought constant, may weaken with time - potentially altering the fate of the universe.

The science behind why the Earth will spin just a little bit faster on July 9, July 22, and August 5, this year.

If dark energy is a constant cosmic acceleration, that means that the universe will die by what astrophysicists call heat death. Everything gets further apart.

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

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." ...

The standard assumption is that the cosmic acceleration rate is itself is at least constant, which will surely result in ultimate heat death of the universe.
