An analysis of 2,884 Type Ia supernovae provides additional evidence that dark energy may change over time rather than remain ...

In an existing theory of gravity, the same present-day matter density can fit two very different histories of the universe.

Add Yahoo as a preferred source to see more of our stories on Google. Astronomers have to use indirect evidence, like the explosions of Type Ia supernovae, to investigate the impacts of dark energy.

Dark energy makes up roughly 70 percent of the universe, yet we know nothing about it. Around 25 percent of the universe is the equally mysterious dark matter, leaving just five percent for everything ...

Rolf Landauer showed that "information is physical" with every bit equivalent to a small amount of energy proportional to temperature. The Landauer equivalent energy of information carried, or ...

The universe has been expanding ever since the Big Bang almost 14 billion years ago, and astronomers believe a kind of invisible force called dark energy is making it accelerate faster. If the result ...

If we find that gravity starts acting weird at the scale of a micron, it could trigger a process of discovery that could ...

Accelerated expansion of the Universe could be an illusion of time Credit: Shad.off / depositphotos.com For decades, dark energy has been one of the most enigmatic concepts in physics, introduced to ...

Around 25 percent of the universe is the equally mysterious dark matter, leaving just five percent for everything that we can see and touch -- matter made up of atoms. Dark energy is the placeholder ...
