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

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 ...

The cosmological constant is the mathematical description of the energy that drives the ever-accelerating expansion of the cosmos. It's also the source of one of the most enduring and confounding ...

Cosmological expansion is widely treated as a proven fact. It is not proven. For nearly a century, cosmology has told a simple story about a universe that began in a hot, dense state and has been ...

Our first concern will be Richard Dawkins’s efforts to refute standard arguments for theism. These efforts suffer from a variety of logical mistakes. His critique of the cosmological argument confuses ...

Larger than expected: artist's impression of the gravitational waves that are emitted just before the merger of two black holes. (Courtesy: LIGO/T Pyle) The observation of black holes with ...

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 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 ...

Our ideas about the Universe are based on a century-old simplification known as the cosmological principle. It suggests that when averaged on large scales, the Cosmos is homogeneous and matter is ...
