Mathematical discovery could shed light on quantum gravity

How can Einstein's theory of gravity be unified with quantum mechanics? It is a challenge that could give us deep insights into phenomena such as black holes and the birth of the universe. Now, a new article in Nature Communications, ...

Dark energy: Neutron stars will tell us if it's only an illusion

A huge amount of mysterious dark energy is necessary to explain cosmological phenomena, such as the accelerated expansion of the Universe, using Einstein's theory. But what if dark energy was just an illusion and general ...

Deep down temperature shifts give rise to eruptions

The astonishing force of the Tonga volcanic eruption shocked the world, but the fact that this underwater volcano actually erupted came as less of a surprise to geoscientists using satellite data to study changes in the temperature ...

How well does concrete work in space?

Concrete is not the first material one usually thinks of when exploring space. Nor is it the focus of much cutting-edge research. The most common building material has been used by humanity for thousands of years. But ...

Astronomers trace galaxy flows across 700 million light years

Everything in our universe moves, but the timescales needed to see motion are often vastly greater than human lifetimes. In a major new study, a team of astronomers from the University of Hawaiʻi Institute for Astronomy ...
