The detection of dark matter, the elusive type of matter predicted to make up most of the universe's mass, is a long-standing ...

Astronomers have long been puzzled by two strange phenomena at the heart of our galaxy. First, the gas in the central ...

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

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

Dr. Richard Lieu, a physics professor at The University of Alabama in Huntsville (UAH), a part of The University of Alabama ...

A new idea about cosmic expansion has emerged that might remove the need for dark matter and dark energy altogether.

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

If dark matter is creating positrons in the CMZ, those particles will eventually slow down and eventually annihilate with electrons in the environment, producing gamma-rays at exactly 511keV energy.

Physicists have proposed a new model of space-time that may provide the 'first observational evidence supporting string ...
