Long and winding road: The Juice space probe taking the long way to Jupiter and its moons – Copyright NASA/AFP/File NASA Scientists have unveiled a new theory that ...

Energy conditions are inequalities imposed on the stress–energy tensor that characterise physically reasonable matter in Einstein’s theory of gravitation. In classical general relativity, the null, ...

A newly merged black hole does not become quiet at once. It vibrates, sheds energy through gravitational waves and produces a ...

The Earth’s gravity, manifested as curvature in space and time, is expected to alter the rules of standard quantum theory. An experiment consisting of three quantum computers at different elevations ...

Ivette Fuentes is a professor of quantum mechanics who conducts experiments at the scales where quantum theory and general relativity interplay ...

Breakthroughs in science often begin with a simple question and years of tireless exploration. From the way tiny molecules slip through microscopic pores to the staggering behavior of matter near ...

The gauge bosons of the standard model of particle physics are responsible for three of the four known forces in the universe, conveyed through the exchange of virtual bosons. In electromagnetism, the ...

The question of how gravity interacts with the quantum world has long perplexed physicists, but a non-quantum theory of space-time could present an answer ...

A new theoretical study offers a possible explanation for how the Universe can grow more complex without violating the second ...

Although general relativity (GR) is an elegant theory of gravity, we don't often need to use it. For most gravitational ...
