The universe’s expansion is accelerating, not decelerating. Our understanding of how the universe works may need an update.

Perlmutter, Riess, and Schmidt attributed this deviation to Einstein’s cosmological constant, which is represented by the Greek letter Lambda, Λ, and is related to the deceleration parameter. Their ...

Teleology is the idea that some processes in nature are directed toward a goal or an end. Today, it is commonly asserted that ...

A new analysis of astronomical data suggests unknown physics is at work assisting dark energy in acting almost as "antigravity," undoing the work of gravity, which clumps together matter to build vast ...

If dark energy is weakening, it stands to reason that eventually gravity will become dominant and the universe will begin to contract. In such a scenario, the universe would collapse back into a ...

However, in 1998, astronomers discovered that it was actually accelerating. The cosmological constant explains this acceleration and is basically an energy density that seems to be an inherent ...
