Last time I wrote about new data that overturns the standard cosmological model. Before anyone starts dusting off their ...

If true, it could mean the universe is destined to collapse rather than expand forever. Einstein proposed the cosmological ...

Astronomers are rethinking one of cosmology’s biggest mysteries: dark energy. New findings show that evolving dark energy models, tied to ultra-light axion particles, may better fit the universe’s ...

We know that the universe is getting bigger. And we know that the speed that the universe is getting bigger is also getting bigger. The standard assumption is that the acceleration rate is itself ...

According to physics, the universe and everything in it can be explained by just a handful of equations. They’re difficult equations, all right, but their simplest feature is also the most mysterious ...

Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe’s greatest mysteries. The widely accepted theory at the present moment ...

The Universe may not have begun with a Big Bang, but instead with a Big Bounce, according to a new theory about how the ...

Physicists are now celebrating the 100th anniversary of the cosmological constant. On this occasion, two recent articles highlight its role in modern physics and cosmology. Before becoming widely ...

A trio of physicists play with the math that describes Bose Einstein condensates. Hidden down behind the BEC's couch, they found a fake cosmological constant that they could use to show why our ...
