While this may complicate the quest for a clear experimental signature of quantum gravity, it does not render such tests useless. According to the research team, both classical and quantum models of ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other ...

Such gravity variations are often caused by variations in the concentration of mass — more mass means more gravity. For example, water currents shift mass around in the ocean, which can lead to ...

As they whirl around in low-Earth orbit, satellite configurations are far more sensitive to changes in Earth's gravity field ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...

As the collapsed core of a massive star, a neutron star is a small but incredibly dense object, packing up to three times the ...

Astronomers have made an exciting breakthrough in the search for the universe’s most mysterious substance—dark matter. They ...

The Indian Ocean Geoid Low ranks as the largest negative "gravity hole" anomaly on Earth, which is why the “thumbprint” jumps ...
