Physicist Richard Lieu first explored the idea that gravity could exist without mass—now he’s got a new cosmological model ...

A new analysis of astronomical data suggests unknown physics is at work assisting dark energy in acting almost as "antigravity," undoing the work of gravity, which clumps together matter to build vast ...

An extremely bold hypothesis proposes transient temporal singularities remove the need for dark matter and dark energy.

New observations of the cosmos show that the dark energy, a mysterious force that accelerates the expansion of the universe, ...

First discovered in the 1990s, dark energy has come to feel like a familiar face of the cosmos. Astronomers first imagined ...

Gravity pulls us to earth, a lesson you learn viscerally the first time you fall. Isaac Newton described gravity as a ...

The physics & astronomy professor joins an international team in detecting solar neutrinos, advancing search for elusive dark ...

Although some compelling evidence exists to support the idea that a repulsive force similar to dark energy exists, it has yet to be directly observed or measured. To circumvent this uncomfortable ...

New hints from one of the most extensive surveys of the cosmos to date suggest that mysterious dark energy may be evolving in ways that could shift how astronomers understand the universe.
