Trying to solve quantum gravity is frustrating. We have made tremendous progress in quantum theory, but it seems that every ...

The far distant fates of the Universe offer a number of possibilities, but if dark energy is truly a constant, as the data indicates, it will continue to follow the red curve, leading to the long-term ...

The long-standing problem of the cosmological constant, described both as “the worst prediction in the history of physics” and by Einstein as his “biggest blunder”, is being tackled with renewed ...

A new study links the universe’s expansion to quantum topology, suggesting that hidden mathematical structures may stabilize ...

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 ...

The cosmological constant is presumably an enigmatic form of matter or energy that acts in opposition to gravity and is considered by many physicists to be equivalent to dark energy. Nobody really ...

Quantum destiny theory: Oxford’s Vlatko Vedral argues that each quantum interaction spawns parallel versions of reality, subtly shaping our personal trajectories. New particle category: Rice ...

As the Dark Energy Survey (DES) releases its final results, we caught up with two physicists who've been involved in the project from its early days. In this Q&A, Josh Frieman, DES co-founder and ...
