For the past generation, we've recognized that our Universe is a particularly dark place. Sure, it's filled with stars, galaxies, and a slew of light-emitting phenomena everywhere we look. But each ...

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 ...

Constant pressure charts illustrate the varying *height* of a specific constant pressure surface (e.g., 500 mb), contrasting with surface charts which depict varying *pressure* at a constant height ...

In every bit of nothing, there is something. If you zoom in on empty space and take out all the planets and stars and galaxies, you might expect a pure vacuum, but you’d be wrong. In­stead you would ...

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 ...

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 ...
